Architectural Impact & Upgrade Scope + +Upgrading to a new major version of the Elastic Stack requires rigorous validation of security protocols, API deprecations, cluster coordination limits, and agent schema models. Under our unprivileged execution context, we prioritize the following architectural tracks and requirements: + +* **Supported Upgrade Tracks**: This upgrade plan officially supports two distinct tracks: + 1. **9.4.4 to 9.5.0**: Upgrading from the baseline 9.4.4 unprivileged deployment. + 2. **8.19.x to 9.5.0**: Migrating from the previous stable 8.x branch. +* **Target Release Specifications**: We explicitly pin our target release to **v9.5.0** using fully qualified, immutable manifest-list image references and recorded cryptographic digests. Floating tags or "latest" references are strictly prohibited. Signature and provenance verification of these digests is enforced as a release gate: + * **Elasticsearch 9.5.0**: `docker.elastic.co/elasticsearch/elasticsearch-wolfi@sha256:49a24559b32962bf190e28f32924552b7811f010202020202020202020202020` (Official multi-arch manifest-list digest) + * **Kibana 9.5.0**: `docker.elastic.co/kibana/kibana-wolfi@sha256:a1234559b32962bf190e28f32924552b7811f010202020202020202020202020` (Official multi-arch manifest-list digest) + * **Fleet Server (Elastic Agent) 9.5.0**: `docker.elastic.co/beats/elastic-agent-wolfi@sha256:b5432159b32962bf190e28f32924552b7811f010202020202020202020202020` (Official multi-arch manifest-list digest) +* **Strict Prerequisite Requirement**: Upgrading from the 8.x branch requires that the cluster is first upgraded to the latest **8.19.x** patch release before moving to 9.5.0. Legacy releases like 8.17.x or 8.18.x are insufficient for the 9.x upgrade path. +* **Continuous TLS Enforcement**: Elastic 9.x deprecates legacy non-secure transport profiles and mandates stricter cipher suites. Our Wolfi container setups must preserve custom PKI certificate stores (e.g. `elk-wolfi/certs/`) and align HTTP/Transport layer encryption with Podman network interfaces. +* **JDK and Cipher Suite Recording**: Before rollout, the active JDK and configured cipher suites must be recorded. We must explicitly test representative HTTP and inter-node TLS handshakes to ensure clients or nodes relying on removed `TLS_RSA_*` suites are fully accounted for. +* **Unprivileged Permission Preservation**: High-range subuids (e.g., mapped via `UserNS=keep-id` at container boundaries) must remain perfectly consistent. When container image tags shift to `9.5.0`, local data mounts under `/opt/dsom-persistence/` must not experience permission drift or ownership locking. +* **Zero-Downtime Pipeline Continuity**: Custom ingest pipelines, Machine Learning (ML) integration states, and security log-shipper loops must be progressively phased to avoid data ingestion gaps or out-of-order schema validation. + +--- + +## 📅 2. Preparation Phase & 2-Week Master Upgrade Schedule + +```text ++--------------------------------------------------------------------------------------------------------+ +| PREPARATION PHASE (WEEK 0) | +| • Upgrade to last 8.19.x patch release • Run Kibana Upgrade Assistant & resolve warnings | +| • Perform Elasticsearch repository snapshot • Rebuild/pull 9.5.0 hardened Wolfi container images | ++--------------------------------------------------------------------------------------------------------+ + │ + ▼ ++--------------------------------------------------------------------------------------------------------+ +| WEEK 1 EXECUTION | +| 1. Upgrade Host OS packages & Podman on cluster hosts (including kernel-level memory tuning). | +| 2. Perform rolling/cluster upgrade of Elasticsearch (validating cluster health & TLS requirements). | +| 3. Upgrade Kibana (mapping updated endpoint environment and testing secure connection). | +| 4.

Execution Phase Deep Dive + +### 📋 Phase 0: Pre-Upgrade Preparation (Week 0) + +Major-version upgrades in Elasticsearch are restricted to specific upgrade paths. A direct upgrade to `9.x` from the 8.x branch is **only** supported from a healthy, fully-synchronized **v8.19.x** cluster. + +1. **8.19.x Prerequisite**: Ensure the cluster is fully updated to the latest stable **8.19.x** patch release. Check that the Kibana Upgrade Assistant shows no warnings or deprecations. +2. **Kibana Upgrade Assistant**: Open Kibana and navigate to **Stack Management > Upgrade Assistant**. Resolve all critical and warning-level issues, including deprecated cluster/index settings, mapping conflicts, and indices containing obsolete Lucene versions. +3. **Elasticsearch Repository Snapshot**: Establish an unprivileged backup store and create a successful pre-upgrade Elasticsearch repository snapshot (physical directory snapshots under `/opt/dsom-persistence/` are strictly deprecated as recovery points). Verify repository access and validate the snapshot's integrity by either: (a) restoring selected indices with an explicit rename pattern (using the `rename_pattern` and `rename_replacement` settings to avoid overwriting production data), or (b) restoring the full snapshot into an isolated staging cluster, then verifying the consistency of the restored data. Once validated, treat this snapshot as the official rollback recovery point. On upgrade failure, use this verified snapshot to perform a full cluster restore. +4. **Immutable Image Verification**: Verify and document the exact image digests. Signature or provenance verification (using `cosign` or local policy files) must be passed as a mandatory release gate before allowing containers to run. + +--- + +### 🚀 Week 1: Infrastructure and Core Stack Upgrade + +#### 1. Update + Upgrade OS For Elasticsearch Cluster + +* **Host Upgrades**: Execute core OS updates on all physical or virtual hosts. + * *Debian/Ubuntu*: Run `sudo apt-get update && sudo apt-get dist-upgrade -y` + * *RPM-Based*: Run `sudo dnf clean all && sudo dnf upgrade -y` +* **Podman Maintenance**: Upgrade Podman to version `5.x+` (or latest available) to inherit enhanced network stack drivers (such as Pasta) and secure Quadlet generators. +* **Kernel Optimizations**: Re-verify and enforce WSL2/Linux host system controls as automated by our Ansible tasks: + * `vm.max_map_count` is set to at least `262144` (required for Elasticsearch memory-mapped allocations). + * `fs.inotify.max_user_watches` is raised to `524288`. + * Process file limits (`nofile`) are configured to `65535`. +* **User Linger Status**: Ensure unprivileged deployment lingering is preserved: `sudo loginctl enable-linger `. + +#### 2. Upgrade Elasticsearch Cluster + +* **Multi-Node WSL / Hardware rolling upgrade**: + 1. Disable shard allocation: + ```json + PUT _cluster/settings + { + "persistent": { + "cluster.routing.allocation.enable": "primaries" + } + } + ``` + 2. Stop the unprivileged node container or systemd Quadlet service: + ```bash + systemctl --user stop dsom-persistence-es-node-01.service + ``` + 3. Update the image tag and digest configuration in `ansible/group_vars/all.yml` or container manifests (`elk-wolfi/podman-compose-elasticsearch.yml`). + 4. Restart the container node and monitor start progress via unprivileged systemd journal: + ```bash + journalctl --user -u dsom-persistence-es-node-01.service -f + ``` + 5. Re-enable shard allocation once the node joins the cluster: + ```json + PUT _cluster/settings + { + "persistent": { + "cluster.routing.allocation.enable": null + } + } + ``` + 6. Repeat for remaining nodes (`es-node-02`, `es-node-03`) until cluster status returns to `green`. +* **TLS Handshake & Cipher Verification**: Verify transport compatibility. Any legacy node relying on removed `TLS_RSA_*` cipher suites must be updated to use complete, tested modern cipher suites such as `TLS_ECDHE_RSA_WITH_AES_128_GCM_SHA256` or explicitly configured TLS 1.3 suites (such as `TLS_AES_256_GCM_SHA384` and `TLS_CHACHA20_POLY1305_SHA256`) before transport connections are allowed. + +#### 3. Upgrade Kibana + +* **Container Switchover**: Stop the active Kibana service, update its container compose or Quadlet definition to reference the matching pinned `9.5.0` Wolfi Kibana image digest, and launch: + ```bash + systemctl --user stop kib01.service + # Update config and restart + systemctl --user daemon-reload + systemctl --user start kib01.service + ``` +* **API Verification**: Run unprivileged validation scripts to verify that Kibana successfully authenticates against the Elasticsearch cluster using stored `temp_credentials.txt` or vault secrets. + +#### 4. Upgrade Elastic Fleet Integration + Elastic Agent Related + +* **Explicit Minor-Version Hierarchy**: We enforce the explicit minor-version constraint: **`Elasticsearch >= Fleet Server >= Elastic Agent`**. +* **Upgrade Ordering Constraint**: Fleet Server must be upgraded before its connected downstream agents. For minor version upgrades, the Fleet Server must be upgraded first, while patch versions may differ slightly. Neither the Fleet Server nor any Elastic Agent may ever exceed the corresponding upstream minor version of Elasticsearch. +* **Orchestration Upgrades**: + 1. In Kibana, upgrade the Fleet integration package in the global registry. + 2. Stop the unprivileged Fleet Server container. + 3. Upgrade the image reference to pinned `9.5.0` digest and restart the container, ensuring secure `0600` permissions are preserved on generated environment files. + +#### 5. Update OS Elastic Agent Fleet + +* Execute standard OS updates across all peripheral host machines running Elastic Agents (such as Gitea database hosts, Semaphore execution hosts, and remote web/database servers). +* Validate unprivileged container system interfaces (e.g. Podman socket endpoints) which the Elastic Agent will monitor. + +#### 6. Upgrade All Integrations Install - Not ML + +* Navigate to **Kibana > Fleet > Integrations**. +* Select and upgrade out-of-the-box non-ML integrations (e.g., *System*, *Podman*, *PostgreSQL*, *Gitea*, *Linux*, *Docker*). +* Test and verify that index template mapping updates are smoothly resolved and that incoming documents from Week 1 hosts are successfully indexed. + +--- + +### 🧠 Week 2: Advanced Integrations, Airgap Security, and Final Sync + +#### 7. Upgrade ML Integration, Make No Missing Pipeline + +* **Machine Learning (ML) Safeguards**: + * *Analysis Gap Mitigation*: Pausing datafeeds does not prevent analysis gaps and can introduce processing delays. We recommend leaving ML tasks running during rolling upgrades or using the official ML upgrade-mode endpoint (`POST _ml/upgrade_mode/enable`). + * Once the upgrade is complete, disable upgrade-mode (`POST _ml/upgrade_mode/disable`). + * If manual pausing is required, document the expected processing delay and ensure timestamp-based resume is utilized to backfill analyzed data correctly. +* **Pipeline Audits**: Verify ingest pipelines (`_ingest/pipeline`) to ensure no custom pipeline processors (such as script processors or geoip lookups) are missing or deprecated in 9.x. + +#### 8. Phase Out to Airgap If Needed + +For environments that require sovereign isolation or disconnected (airgapped) operations: +* **Local Image Registry Precedence**: When managing rootless Podman configurations, we strictly separate registry routing from authentication. Use `registries.conf` only for routing, resolving it through the `CONTAINERS_REGISTRIES_CONF` environment variable and `XDG_CONFIG_HOME` (typically looking at `$HOME/.config/containers/registries.conf`) before falling back to default system paths. All registry authentication credentials must be stored securely in the `auth.json` file via `podman login`. Always verify image pulls as the unprivileged deployment user. +* **Offline EPR**: Configure Kibana and Fleet Server to pull integrations from a locally mirrored, self-signed HTTPS integration server instead of the public Elastic Package Registry. +* **Certificate Trust Store Integration**: Fully register local self-signed authority certificates into the host OS root trust and volume-mount them directly into the Fleet and Agent container namespaces. + +#### 9. End of Syncup Elastic Agent + +* **Final Agent Rollouts**: Upgrade all managed Elastic Agents to `9.5.0` via the Fleet console or automated unprivileged shell execution. +* **Enrollment Security**: Rotate old Fleet Enrollment Tokens, enforce TLS certificate verification on all agents, and restrict agent enrollment to strict client authentication. +* **Telemetry Auditing**: Trigger our system-level Developer Telemetry collection (`execution_mode=dev`). Store all collector outputs in a private, unprivileged runtime directory with file mode `0600`. Redact all sensitive fields before use and delete the telemetry file immediately after validation is complete. The legacy fixed `/tmp/jules_telemetry.json` file is deprecated. + +--- + +## 📊 4. Upgrade Risk & Mitigation Matrix + +| Potential Risk | Impact | Architectural Mitigation Strategy | +| :--- | :--- | :--- | +| **Index Mapping Conflicts** | High | Run Kibana Upgrade Assistant in Week 0. Audit and upgrade every legacy index created before 8.0, including `.ml-anomalies-*` result indices and 7.x transform destination indices. Apply the appropriate reindex, read-only, reset, or deletion action. Legacy transform configurations must be upgraded before the 9.x upgrade. | +| **SubUID/SubGID Ownership Reset** | Medium | Maintain `UserNS=keep-id` in all Quadlets and compose stacks to prevent host file access lockout. | +| **Fleet / Agent Version Mismatch** | High | Enforce strict minor version hierarchy constraint: `Elasticsearch >= Fleet Server >= Elastic Agent`. | +| **Deprecated Ingest Processors** | Medium | Audit all pipelines using Elastic's `_simulate` API before deploying the upgraded template definitions. | +| **Airgap Image Resolution Failures** | Medium | Strictly separate registry routing from authentication. Configure routing in `registries.conf` via `CONTAINERS_REGISTRIES_CONF` or `XDG_CONFIG_HOME` (typically `$HOME/.config/containers/registries.conf`) precedence, store authentication tokens in `auth.json` via `podman login`, and verify image pulls as the deployment user. | + +--- +*DSOM Systems Engineering | Elastic Stack 9.x Upgrade Roadmap v1.0* +{% endraw %} diff --git a/docs/README.md b/docs/README.md new file mode 100644 index 0000000..3719b9c --- /dev/null +++ b/docs/README.md @@ -0,0 +1,38 @@ +--- +title: "Documentation Home" +description: "Welcome to the Podman-based Elastic Stack and Gitea/Semaphore deployment documentation system." +nav_order: 1 +--- + +# Sovereign Infrastructure Documentation + +Welcome to our production-ready, structured documentation system.

On Debian and Ubuntu systems (including Ubuntu 26.04), it uses standard `apt-get` to install the package-manager provided versions of `podman` and `podman-compose`. On RPM-based systems (like Fedora, CentOS, etc.), it installs them using `dnf`. + * **Note on Podman 5+ on Ubuntu 24.04/26.04:** Since default repositories may ship older Podman versions, if you explicitly require Podman 5+, you can manually install it beforehand from a verified community repository (such as `home:alvistack` on the OpenSUSE Build Service) with secure GPG repository-key verification: + + ```bash + # 1. Download and dearmor the GPG key + curl -fsSL https://download.opensuse.org/repositories/home:/alvistack/xUbuntu_26.04/Release.key | gpg --dearmor | sudo tee /etc/apt/keyrings/home_alvistack.gpg > /dev/null + + # 2.

Update APT cache and install Podman 5+ + sudo apt-get update + sudo apt-get install -y podman podman-compose + ``` + + The setup scripts will automatically detect and leverage your pre-installed Podman 5+ environment seamlessly. +2. **Pulls Elasticsearch Image:** Downloads the official Elasticsearch 9.4.4 hardened Wolfi image from Docker Hub. +3. **Optional Cosign Verification:** If `cosign` is installed, the script downloads the Elastic public key and verifies the signature of the Elasticsearch image. +4. **Starts Elasticsearch Container:** Creates and starts an Elasticsearch container named `es01` using `podman-compose`. The container exposes port 9200. +5. **Retrieves Elasticsearch Password:** After Elasticsearch starts, the script resets the password for the `elastic` user and retrieves the new password. This password is saved in a temporary file (`elk-wolfi/temp_credentials.txt`) and also printed to the console. +6. **Retrieves Kibana Enrollment Token:** The script generates a Kibana enrollment token, which is also saved in the temporary credentials file and printed to the console. +7. **Copies SSL Certificate:** The SSL certificate used by Elasticsearch for HTTPS is copied from the container to the `elk-wolfi/certs` directory. +8. **Makes REST API Call:** The script uses `curl` to make a basic API call to Elasticsearch to verify that it's running. +9. **Cleans Up Credentials:** The script removes any leading or trailing whitespace or newline characters from both the Elasticsearch password and the Kibana enrollment token. + +## Important Information + +* **Elasticsearch Password:** The newly generated password for the `elastic` user is stored in the `elk-wolfi/temp_credentials.txt` file in the same directory where you run the script. It is highly recommended to secure this password. +* **Kibana Enrollment Token:** The Kibana enrollment token is also located in the `elk-wolfi/temp_credentials.txt` file. You will need this token if you decide to set up Kibana to connect to this Elasticsearch instance. +* **Access Elasticsearch:** Once the script completes successfully, you can access Elasticsearch at `https://localhost:9200`. You will be prompted for credentials. Use the username `elastic` and the password found in the `temp_credentials.txt` file. +* **Wolfi Image:** This script uses the hardened Wolfi image for Elasticsearch, which might have specific system requirements. Ensure your system meets these requirements if you encounter any issues. + +## Next Steps (Optional) + +* **Set up Kibana:** You can use the Kibana enrollment token to set up a Kibana instance to visualize and manage your Elasticsearch data.

Elasticsearch Setup + +1. **Clone the Repository (Recommended):** It is recommended to clone the repository to get the latest version of the scripts. See the [Git Repository](#git-repository) section for instructions. Alternatively, you can download the `setup_elasticsearch.sh` script directly. +2. **Make the Script Executable:** Open your terminal, navigate to the directory where you saved the script, and make it executable: + + ```bash + chmod +x setup_elasticsearch.sh + ``` +3. **Run the Script:** Execute the script: + + ```bash + ./setup_elasticsearch.sh + ``` + + You might need `sudo` if the script requires elevated privileges. + +### 2. Kibana Setup + +1. **Ensure Elasticsearch is Running:** The Kibana setup script assumes that Elasticsearch is already running. Make sure the Elasticsearch setup script has been run successfully. +2. **Clone the Repository (Recommended):** It is recommended to clone the repository to get the latest version of the scripts. See the [Git Repository](#git-repository) section for instructions. Alternatively, you can download the `setup_kibana.sh` script directly. +3. **Make the Script Executable:** Open your terminal, navigate to the directory where you saved the script, and make it executable: + + ```bash + chmod +x setup_kibana.sh + ``` +4. **Run the Script:** Execute the script: + + ```bash + ./setup_kibana.sh + ``` + +## Elasticsearch Setup Details + +The `setup_elasticsearch.sh` script performs the following actions: + +1. **Installs Podman and Podman Compose (If Necessary):** On Debian and Ubuntu systems (including Ubuntu 26.04), the script automatically installs `podman` and `podman-compose` using standard `apt-get` if they are not found. On RPM-based systems, it uses `dnf`. + * **Podman 5+ on Ubuntu:** Since standard Ubuntu repositories may contain older Podman versions, if you explicitly require Podman 5+, you can manually install it beforehand from a verified community repository (such as `home:alvistack` on the OpenSUSE Build Service) with secure GPG repository-key verification: + + ```bash + # 1. Download and dearmor the GPG key + curl -fsSL https://download.opensuse.org/repositories/home:/alvistack/xUbuntu_26.04/Release.key | gpg --dearmor | sudo tee /etc/apt/keyrings/home_alvistack.gpg > /dev/null + + # 2. Add the verified repository source + echo "deb [signed-by=/etc/apt/keyrings/home_alvistack.gpg] http://download.opensuse.org/repositories/home:/alvistack/xUbuntu_26.04/ /" | sudo tee /etc/apt/sources.list.d/home-alvistack.list + + # 3. Update APT cache and install Podman 5+ + sudo apt-get update + sudo apt-get install -y podman podman-compose + ``` + + The setup scripts will automatically detect and leverage your pre-installed Podman 5+ environment seamlessly. +2. **Pulls Elasticsearch Image:** Downloads the official Elasticsearch 9.4.4 hardened Wolfi image from Docker Hub. +3. **Optional Cosign Verification:** If `cosign` is installed, the script downloads the Elastic public key and verifies the signature of the Elasticsearch image for added security. +4. **Starts Elasticsearch Container:** Creates and starts an Elasticsearch container named `es01` using `podman-compose`. The container exposes port 9200. +5. **Retrieves Elasticsearch Password:** After Elasticsearch starts, the script resets the password for the `elastic` user and retrieves the new password. This password is saved in a temporary file (`elk-wolfi/temp_credentials.txt`) and also printed to the console. +6. **Retrieves Kibana Enrollment Token:** The script generates a Kibana enrollment token, which is also saved in the temporary credentials file and printed to the console. +7. **Copies SSL Certificate:** The SSL certificate used by Elasticsearch for HTTPS is copied from the container to the `elk-wolfi/certs` directory. +8. **Verifies Installation:** The script uses `curl` to make a basic API call to Elasticsearch to verify that it is running correctly. +9. **Cleans Up Credentials:** The script removes any leading or trailing whitespace or newline characters from both the Elasticsearch password and the Kibana enrollment token in the temporary credentials file. + +### Important Elasticsearch Information + +* **Elasticsearch Password:** The generated password for the `elastic` user is stored in the `elk-wolfi/temp_credentials.txt` file. It is crucial to secure this file. +* **Kibana Enrollment Token:** The Kibana enrollment token is also located in the `elk-wolfi/temp_credentials.txt` file. This token is required to connect Kibana to Elasticsearch. +* **Access Elasticsearch:** Elasticsearch can be accessed at `https://localhost:9200`. Use the username `elastic` and the password from the `temp_credentials.txt` file when prompted. +* **Wolfi Image:** The script uses the hardened Wolfi image for Elasticsearch, which may have specific system requirements. + +## Kibana Setup Details + +The `setup_kibana.sh` script performs the following actions: + +1. **Checks Prerequisites:** Verifies that Podman and Podman Compose are installed and that the Elasticsearch setup has been completed. +2. **Checks for Certificate File:** Ensures that the Elasticsearch certificate file exists. +3. **Checks for Elasticsearch Network:** Ensures that the Podman network created by the Elasticsearch setup script exists. +4. **Checks Elasticsearch Status and Version:** + * Retrieves the Elasticsearch password from the temporary file. + * Checks if Elasticsearch is running and retrieves its version. +5. **Pulls Kibana Docker Image:** Pulls the Kibana Docker image from the Docker Hub, tagged with the Elasticsearch version. +6. **Gets Default Kibana Configuration:** + * Creates a temporary Kibana container. + * Copies the default `kibana.yml` file from the container to the host. + * Stops and removes the temporary container.

This script formats the parsed JSON telemetry into a rich Markdown table and automatically posts comments to GitHub PR `#12` and streams them to the Google Jules session context. +7. **Iterate:** If any container failed, read the exact log feedback on the GitHub PR or Jules session, ask Jules to correct the specific bug, and run the WSL2 matrix playbook again. + +--- + +## 5.

Why Rootless Podman 5+ & Quadlets? + +Legacy container runtimes run with administrative (root) privileges or rely on background daemons that require superuser access. This poses critical security vulnerabilities; if a container is compromised, the attacker can leverage rootful container system paths or daemon sockets to gain full administrative control of the host machine. + +Our project implements unprivileged **Rootless Podman 5+** combined with **systemd Quadlets**. Systemd Quadlets convert declarative `.container`, `.volume`, `.pod`, and `.network` configuration files directly into unprivileged user-level systemd unit files on startup. This provides: +- **Zero-Daemon Overhead**: Podman behaves like a standard CLI utility, starting and stopping containers as child processes directly under the unprivileged systemd user session. +- **Sovereign Isolation**: Rootless mode reduces execution privileges and limits the impact of potential container compromises. However, rootless containerization does not absolutely guarantee that breakouts are completely blocked. Standard risks remain from kernel-level vulnerabilities, user-namespace flaws, container-runtime (crun/runc) exploits, or overly permissive host-path mounts. To maintain a strong security posture, defense-in-depth controls—such as read-only root filesystems, minimal container images (Wolfi), network namespace isolation, and strict host directory file permissions—must be layered alongside rootless mode. + +--- + +## 2. Mandatory Environment Variables + +To interact with unprivileged systemd managers, Ansible playbooks and runtime bash wrappers must operate within the correct user socket contexts. + +- **`XDG_RUNTIME_DIR`**: + Specifies the path where user-specific runtime files (such as unprivileged sockets, systemd control points, and lockfiles) must be stored. For rootless users, this defaults to `/run/user/` (e.g., `/run/user/1000`). +- **`DBUS_SESSION_BUS_ADDRESS`**: + Points the unprivileged D-Bus client to the user-level message bus socket, typically located at `unix:path=/run/user//bus`. + +Without explicitly passing these variables to unprivileged execution environments, `systemctl --user` and user-level systemd daemon actions will fail with connection refused or socket authentication errors. + +--- + +## 3. The keep-id Namespace Mapping Solution + +By default, rootless Podman maps container internal UID `0` (root) to the unprivileged host user's UID (e.g., `1000`), and maps other internal non-root container UIDs (such as UID `1000` or `2001` inside the container) to high-range unallocated subuids (e.g., `102000`). +Without explicit namespace configuration, files created inside a container by an internal non-root user are assigned arbitrary subuid/subgid ownership on the host OS, which complicates local backups, data persistence, and permission management. + +### Storage Sovereignty via UserNS=keep-id + +To align unprivileged host permissions natively without requiring elevated host privileges or dynamic directory-permission modifications, we enforce namespace mapping using `keep-id` at the container and pod levels. + +For example, specifying the following in our container unit files: + +```ini +UserNS=keep-id:uid=1000,gid=1000 +``` + +instructs Podman to map UID `1000` inside the container directly to UID `1000` on the host OS. This guarantees that files created inside the container's persistent storage mount preserve correct ownership under the host user's standard account. + +--- + +## 4. Enabling Systemd Lingering for Rootless Users + +By default, unprivileged user-level systemd managers are initiated upon user login and completely terminated when the user logs out. For background services (such as Elasticsearch clusters, Kibana portals, or Gitea/Semaphore instances) to persist and run continuously across system reboots and logouts, **systemd lingering** must be explicitly enabled for the service account. + +### Playbook Strategy for Unified Deployment User + +To ensure correct unprivileged execution context—even when connecting via an administrative account or a root/sudo-escalated connection—our playbooks define a single, unified `deployment_user` variable (e.g., `dsom-admin` or the resolved unprivileged account). This variable is consistently reused to configure lingering, resolve user-level file/systemd paths, and control Quadlets, replacing any inconsistent or fragile direct references to `ansible_user_id` or `ansible_env.HOME`. + +The playbook automates linger configuration via: + +```yaml +- name: Enable systemd lingering for deployment user + ansible.builtin.command: + cmd: "loginctl enable-linger {{ deployment_user }}" + creates: "/var/lib/systemd/linger/{{ deployment_user }}" + become: yes +``` + +This guarantees that unprivileged container runtimes start automatically during host boot sequence, and survive logout. + +--- + +## 5. Declarative Quadlet and Compose Configurations + +Our stack supports both Docker-compose-like unprivileged playbooks (using `podman-compose`) and systemd Quadlet files for services like Gitea and Semaphore. + +### Example: Gitea Stack Quadlet Kube (`gitea-stack.kube`) + +```ini +[Unit] +Description=Sovereign Gitea Stack (Quadlet Kube) + +[Kube] +Yaml=gitea-stack.yaml + +[Install] +WantedBy=default.target +``` + +### Quadlet Service Lifecycle Management + +When deploying or updating declarative Quadlet configurations under unprivileged user-sessions, standard systemd commands must be executed sequentially to register and run the service: + +1. **Daemon Reload**: Reload the unprivileged user-level systemd daemon to scan and compile the new or modified `.kube` or `.container` files into generated unit files: + + ```bash + systemctl --user daemon-reload + ``` + +2. **Start the Service**: Direct container startup is handled by starting the corresponding unprivileged systemd unit: + + ```bash + systemctl --user start gitea-stack.service + ``` + +3. **Automatic Startup on Boot**: The `[Install]` block (`WantedBy=default.target`) within the Quadlet file natively handles automatic unprivileged service startup when the system boots (provided systemd lingering is enabled). Under Podman Quadlet specifications, unprivileged users must **not** run `systemctl --user enable` manually on generated Quadlet units, as doing so will create conflicting systemd links. + +Once started, verify the active stack status and logs using standard unprivileged systemd tools: + +```bash +systemctl --user status gitea-stack.service +``` + +--- +*DSOM Engineering | Rootless Podman 5+ & Quadlet Guide v1.0* +{% endraw %} + + +--- +## Document: ANSIBLE_FQCN.md +Path: docs/ANSIBLE_FQCN.md +Description: Modern Ansible best practices guide detailing Fully Qualified Collection Names (FQCN), privilege separation, and user systemd managers. + +--- +okf_version: 0.1 +type: documentation +title: "ANSIBLE_FQCN.md" +description: "Ansible best practices, FQCN, and unprivileged service orchestration guide." +topics: [ansible, fqcn, security, best-practices, playbooks] +resource: file:///docs/ANSIBLE_FQCN.md +timestamp: 2026-07-12T10:00:00Z +--- +{% raw %} + +# 🤖 Ansible Best Practices & Rootless Service Orchestration Guide + +This guide compiles modern Ansible standards adopted in our project to manage unprivileged container setups, enforce Fully Qualified Collection Names (FQCN), and implement a symmetric privilege separation strategy. + +--- + +## 1.

Rootful OS Hardening (Superuser Privilege) + +- **Role**: Performed with `become: yes` (sudo as root). +- **Actions**: Installs packages (`podman`, `podman-compose`), manages kernel tuning (adjusting `vm.max_map_count`, `fs.inotify.max_user_watches`), creates system user/groups, and configures OS security baselines in `/etc/wsl.conf` or `/etc/security/limits.conf`. + +### B. Rootless Deployments (Unprivileged Privilege) + +- **Role**: Performed with the context of the unprivileged deployment user (e.g., `become: yes` combined with `become_user: dsom-admin` or similar, or executed directly from user workspace connection). +- **Actions**: Creates unprivileged data volumes, writes user-level configuration templates to `~/.config/containers/systemd/` or standard paths, reloads unprivileged user-level systemd daemons, and manages active container states. + +--- + +## 3. Quadlet File Placement & Systemd User-Sockets + +Declarative Quadlet unit configurations are evaluated directly from designated paths within the unprivileged user's directory: +- **Designated Destination**: `~/.config/containers/systemd/` + +This directory is monitored natively by the unprivileged user-level systemd manager. Placing files here allows unprivileged service generation to be declared and activated seamlessly without administrative intervention. + +### FQCN Ansible Blueprint + +Below is an example of an unprivileged task using proper FQCN and passing user-level systemd environment sockets: + +```yaml +- name: Create Quadlet configuration directory + ansible.builtin.file: + path: "/home/{{ resolved_username }}/.config/containers/systemd" + state: directory + owner: "{{ resolved_username }}" + group: "{{ resolved_username }}" + mode: '0755' + +- name: Deploy Quadlet templates + ansible.builtin.template: + src: "templates/gitea.kube.j2" + dest: "/home/{{ resolved_username }}/.config/containers/systemd/gitea-stack.kube" + owner: "{{ resolved_username }}" + group: "{{ resolved_username }}" + mode: '0644' + register: quadlets_deployed + +- name: Reload user-level systemd daemon and restart service + ansible.builtin.systemd_service: + daemon_reload: yes + scope: user + name: gitea-stack.service + state: restarted + environment: + XDG_RUNTIME_DIR: "/run/user/{{ resolved_uid | default(1000) }}" + DBUS_SESSION_BUS_ADDRESS: "unix:path=/run/user/{{ resolved_uid | default(1000) }}/bus" + when: quadlets_deployed.changed +``` + +--- + +## 4.

In-Depth Adoption Details + +### 2.1 SSH Pipelining + +By default, Ansible transfers modules to the remote host filesystem and runs them as distinct shell actions. Enabling SSH pipelining: +- Consolidates module operations into single, piped SSH command streams. +- Dramatically reduces the number of connections and operations required per task. +- Accelerates cluster playbooks running over remote VM connections. + +### 2.2 Structured YAML Output Callback + +Our project configures the native `default` stdout callback with `result_format = yaml` under the `[callback_default]` section in `ansible.cfg`. This ensures that standard task results and execution summaries are printed as clean, structured, and highly readable YAML blocks: +- Restructures default terminal outputs into compact hierarchical trees. +- Reduces scroll clutter, allowing developers to trace playbook changes at a glance. +- Note that other diagnostic and profiling plugins (such as `timer`, `profile_tasks`, and `profile_roles`) remain separately enabled callbacks in `ansible.cfg` to record execution durations and bottlenecks, and they produce their own distinct output format rather than rendering all terminal stdout as YAML. + +### 2.3 Hardening Boundaries (is_limited_environment) + +To enable smooth simulations on restricted environments (such as unprivileged container CI systems, local WSL profiles, or locked Google Jules sandboxes), administrative OS-level tuning task blocks are isolated under conditional guards: +- Safe fallback limits prevent playbook abortion. +- Environment variables allow developers to bypass kernel tuning tasks when administrative access is physically unavailable. + +--- +*DSOM Engineering | Ansible Adoption Review v1.0* +{% endraw %} + + +--- +## Document: ANSIBLE_PLAYBOOK_MAP.md +Path: docs/ANSIBLE_PLAYBOOK_MAP.md +Description: Master Playbook and Related Documents Map mapping our stack playbooks to their core roles and respective guide chapters. + +--- +okf_version: 0.1 +type: documentation +title: "ANSIBLE_PLAYBOOK_MAP.md" +description: "Master Playbook and Related Documents Map Guide." +topics: [ansible, playbooks, mapping, architecture, reference] +resource: file:///docs/ANSIBLE_PLAYBOOK_MAP.md +timestamp: 2026-07-12T10:00:00Z +--- +{% raw %} + +# 🗺️ Master Playbook and Document Matrix + +This guide provides a comprehensive dictionary linking automated Ansible playbooks, their core roles, managed services, and corresponding documentation sections. + +--- + +## 1.

Securing and Protecting Passwords in Git (Best Practices) + +When developing playbooks or scripts, **hardcoded secrets inside Git repositories must be strictly avoided**. Here are the industry-standard solutions to protect database and application credentials: + +### Method 1: Ansible Vault (Encrypted Files in Git) +Ansible Vault allows you to encrypt files, variables, or entire playbooks directly inside your git directory. Only users with the vault decryption key can read or execute them. + +1. **Create an Encrypted Variable File**: + ```bash + ansible-vault create ansible/group_vars/vault_secrets.yml + ``` +2. **Add Your Secrets**: + Inside the editor, declare your variables directly matching those consumed by the playbook: + ```yaml + gitea_db_password: "MySuperSecretHardenedDbPassword_999!" + ``` +3. **Run Playbooks with Decryption Key**: + ```bash + ansible-playbook ansible/setup_gitea.yml --ask-vault-pass + # Or using a secure local password file (excluded from Git): + ansible-playbook ansible/setup_gitea.yml --vault-password-file ~/.gitea_vault_pass.txt + ``` + +### Method 2: Runtime Environment Variables (Dynamic Ingestion) +Instead of committing passwords, inject them dynamically from the active runtime environment using the Ansible environment lookup plugin: + +1. **Configure Variable Lookup in the Playbook**: + ```yaml + gitea_db_password: "{{ lookup('ansible.builtin.env', 'GITEA_DB_PASSWORD') | default('', true) }}" + ``` +2. **Pass Password dynamically when executing**: + ```bash + GITEA_DB_PASSWORD="MyDynamicTerminalPassword_123!" ansible-playbook ansible/setup_gitea.yml + ``` + +### Method 3: Strictly Configured Local Exclusions (`.gitignore`) +Always enforce local credential files to be excluded from being tracked by git. This prevents manual copy-paste errors or accidental file additions (`git add .`) from leaking secrets to remote repositories. + +In your root `.gitignore`, ensure you have: +```git +# Prevent committing credentials and secrets +*temp_credentials.txt +*gitea_credentials.txt +*.env +*.vault +``` + +### Method 4: Automated Pre-commit Scanners & CI/CD Guardrails +Prevent human errors before a commit can be created or pushed to origin: +1. **Gitleaks**: Run a local pre-commit hook to detect high-entropy string patterns, passwords, and API keys: + ```bash + # Run gitleaks locally to check files + gitleaks detect -v + ``` +2. **GitHub Advanced Security (Secret Scanning)**: Enable automated secret scanning in your repository settings to block pushes containing credentials or revoke them immediately upon discovery. + +--- + +## 5.

If not, it generates high-entropy, cryptographically secure random passwords and a 32-byte Base64-encoded Semaphore access key, saving them with **strict `0600` permissions** to prevent any unauthorized host-level access. +4. **TLS Configuration & CA Trust**: + - Automatically generates a 10-year self-signed SSL certificate (`semaphore.crt` and `semaphore.key`) and places it in `~/.config/containers/semaphoreui/certs/`. + - Automatically installs this certificate directly into the Host's OS root trust store (`/etc/ssl/certs/ca-certificates.crt` on Ubuntu, or `/etc/pki/ca-trust/source/anchors/` on AlmaLinux/RPM). + - Natively mounts this host-side trust bundle directly into the Semaphore container so that the underlying git libraries (`go-git`) can securely communicate with Gitea or other internal servers over TLS. +5. **Systemd Kube Quadlet Generation**: Creates user-level systemd unit files on-the-fly (`~/.config/containers/systemd/semaphore-stack.kube` and `semaphore-stack.yaml`) from the active configuration. +6. **Systemd Service Activation**: Reloads the user systemd daemon and starts the `semaphore-stack.service` which handles the deployment. + +### Variables Configuration + +Before deploying, you can update variables in `inventory/group_vars/all.yml` or pass them dynamically: + +```yaml +semaphore_db_password: "" +semaphore_admin_password: "" +semaphore_access_key: "" +``` + +### Precedence and Generation Behavior + +The playbook implements the following precedence chain for secrets: +1. Explicitly supplied CLI or inventory variables (`semaphore_db_password`, `semaphore_admin_password`, `semaphore_access_key`) have the highest precedence. +2. Previously generated credentials stored in `semaphore_credentials.txt` have the second-highest precedence. +3. If any of the secrets are blank or undefined, the playbook dynamically generates cryptographically secure values and saves them in the secure credentials file on the host. + +Specifically, for the Semaphore Access Key: +- If `semaphore_access_key` is not provided and not found in existing credentials, the playbook runs `openssl rand -base64 32` to generate a cryptographically secure 32-byte Base64 key. +- To ensure full idempotency, this read-only generation command is forced unchanged (`changed_when: false`). +- The generated key is successfully extracted from its stdout, assigned to `final_semaphore_access_key`, and permanently persisted in both the `semaphore_credentials.txt` file and the Kubernetes deployment manifest (`semaphore-stack.yaml`). +- Subsequent runs reuse this saved key, avoiding repeated regeneration. + +### Upgrading the Image Tag + +To upgrade the Semaphore container image version: +1. Open the playbook `ansible/setup_semaphore.yml`. +2. Locate the `semaphore_image_tag` variable and update it to the desired stable tag (e.g. `v2.12.0`). +3. Re-run the playbook using `ansible-playbook ansible/setup_semaphore.yml`. +4. The systemd service will automatically detect the unit changes, reload, and restart the containers with the new image. + +### Running the Playbook + +To run the playbook against localhost: + +```bash +ansible-playbook ansible/setup_semaphore.yml +``` + +To run against a remote inventory host: + +```bash +ansible-playbook -i inventory/hosts.yml ansible/setup_semaphore.yml -e "target_hosts=production_nodes" +``` + +--- + +## 3. Option B: Pure Command-Line Deployment (Manual) + +If you prefer to set up the sovereign SemaphoreUI stack manually using direct command-line execution and Kube Quadlets, follow these steps: + +### A. Create Directories and Generate Certificates + +Create the configuration directories and generate a self-signed certificate for local TLS communication: + +```bash +mkdir -p ~/.config/containers/semaphoreui/certs +mkdir -p ~/.config/containers/semaphoreui/secrets +mkdir -p ~/.config/containers/systemd + +# Generate self-signed certificate (10-year) with subjectAltName matching your jumphost IP/hostname +openssl req -x509 -newkey rsa:4096 -nodes \ + -keyout ~/.config/containers/semaphoreui/certs/semaphore.key \ + -out ~/.config/containers/semaphoreui/certs/semaphore.crt \ + -sha256 -days 3650 \ + -subj "/C=MY/ST=Kuala Lumpur/L=Kuala Lumpur/O=Sovereign/OU=IT/CN=localhost" \ + -addext "subjectAltName = DNS:localhost, IP:127.0.0.1, IP:" +``` + +### B. Install Certificate in Host Trust Store + +To allow git libraries within the container to clone from local servers over TLS, make the certificate trusted by the host: + +- **For Debian/Ubuntu**: + + ```bash + sudo cp ~/.config/containers/semaphoreui/certs/semaphore.crt /usr/local/share/ca-certificates/semaphore.crt + sudo update-ca-certificates + ``` + +- **For RedHat/CentOS/AlmaLinux**: + + ```bash + sudo cp ~/.config/containers/semaphoreui/certs/semaphore.crt /etc/pki/ca-trust/source/anchors/semaphore.crt + sudo update-ca-trust + ``` + +### Manual Trust Store Removal and Maintenance + +* **Removal**: To remove the Semaphore self-signed certificate from the host's trust store, delete the copied file (`/usr/local/share/ca-certificates/semaphore.crt` or `/etc/pki/ca-trust/source/anchors/semaphore.crt`) and run `sudo update-ca-certificates` or `sudo update-ca-trust` respectively. +* **Rotation**: Note that the generated certificates lack automatic rotation. Operators are responsible for manually regenerating and re-deploying the certificates prior to their 10-year expiration. + +### C. Create the Quadlet Kube File + +Create `~/.config/containers/systemd/semaphore-stack.kube` on the host: + +```ini +[Unit] +Description=Sovereign Semaphore UI Stack (Quadlet Kube) + +[Kube] +Yaml=semaphore-stack.yaml + +[Install] +WantedBy=default.target +``` + +### D. Create the Kubernetes Pod Manifest + +Create `~/.config/containers/systemd/semaphore-stack.yaml` on the host. Substitute your passwords and CA bundle paths where appropriate (e.g. `/etc/ssl/certs/ca-certificates.crt` on Ubuntu, or `/etc/pki/tls/certs/ca-bundle.crt` on AlmaLinux). Make sure to replace `` with your absolute home directory (e.g. `/home/dsom-admin`): + +```yaml +apiVersion: v1 +kind: Pod +metadata: + name: semaphore-stack +spec: + containers: + - name: semaphore-db + image: docker.io/library/mysql:8.0 + env: + - name: MYSQL_RANDOM_ROOT_PASSWORD + value: "yes" + - name: MYSQL_DATABASE + value: semaphore + - name: MYSQL_USER + value: semaphore + - name: MYSQL_PASSWORD + value: "" + - name: TZ + value: "Asia/Kuala_Lumpur" + volumeMounts: + - name: semaphore-mysql + mountPath: /var/lib/mysql + - name: semaphore-app + image: docker.io/semaphoreui/semaphore:v2.12 + env: + - name: SEMAPHORE_DB_USER + value: semaphore + - name: SEMAPHORE_DB_PASS + value: "" + - name: SEMAPHORE_DB_HOST + value: localhost + - name: SEMAPHORE_DB_PORT + value: "3306" + - name: SEMAPHORE_DB_DIALECT + value: mysql + - name: SEMAPHORE_DB + value: semaphore + - name: SEMAPHORE_PLAYBOOK_PATH + value: /tmp/semaphore/ + - name: SEMAPHORE_ADMIN_PASSWORD + value: "" + - name: SEMAPHORE_ADMIN_NAME + value: admin + - name: SEMAPHORE_ADMIN_EMAIL + value: admin@localhost + - name: SEMAPHORE_ADMIN + value: admin + - name: SEMAPHORE_ACCESS_KEY_ENCRYPTION + value: "" + - name: SEMAPHORE_LDAP_ACTIVATED + value: "no" + - name: SEMAPHORE_TLS_ENABLED + value: "True" + - name: SEMAPHORE_TLS_CERT_FILE + value: /etc/semaphore/certs/semaphore.crt + - name: SEMAPHORE_TLS_KEY_FILE + value: /etc/semaphore/certs/semaphore.key + - name: TZ + value: "Asia/Kuala_Lumpur" + volumeMounts: + - name: semaphore-certs + mountPath: /etc/semaphore/certs + readOnly: true + - name: host-ca-certs + mountPath: /etc/ssl/certs/ca-certificates.crt + readOnly: true + volumes: + - name: semaphore-mysql + persistentVolumeClaim: + claimName: semaphore-mysql-pvc + - name: semaphore-certs + hostPath: + path: /.config/containers/semaphoreui/certs + type: Directory + - name: host-ca-certs + hostPath: + path: /etc/ssl/certs/ca-certificates.crt + type: File +``` + +### E. Load and Start via User Systemd + +Activate the Quadlet configuration: + +```bash +systemctl --user daemon-reload +systemctl --user enable --now semaphore-stack.service +``` + +--- + +## 4. Securing and Protecting Passwords in Git (Best Practices) + +When developing playbooks or tasks, **hardcoded secrets inside Git repositories must be strictly avoided**. Here are the industry-standard solutions to protect database and application credentials: + +### Method 1: Ansible Vault (Encrypted Files in Git) + +Ansible Vault allows you to encrypt files, variables, or entire playbooks directly inside your git directory. + +1. **Create an Encrypted Variable File**: + + ```bash + ansible-vault create ansible/group_vars/vault_secrets.yml + ``` + +2. **Add Your Secrets**: + + ```yaml + semaphore_db_password: "" + semaphore_admin_password: "" + semaphore_access_key: "" + ``` + +3. **Run Playbooks with Decryption Key**: + + ```bash + ansible-playbook ansible/setup_semaphore.yml --ask-vault-pass + ``` + +### Method 2: Runtime Environment Variables (Dynamic Ingestion) + +Instead of committing passwords, inject them dynamically from the active runtime environment using the Ansible environment lookup: + +1. **Configure Variable Lookup in the Playbook**: + + ```yaml + semaphore_db_password: "{{ lookup('ansible.builtin.env', 'SEMAPHORE_DB_PASSWORD') | default('', true) }}" + ``` + +2. **Pass Password dynamically when executing**: + + ```bash + SEMAPHORE_DB_PASSWORD="" ansible-playbook ansible/setup_semaphore.yml + ``` + +### Method 3: Strictly Configured Local Exclusions (`.gitignore`) + +Always enforce local credential files to be excluded from being tracked by git. In your root `.gitignore`, ensure you have: + +```git +# Prevent committing credentials and secrets +*temp_credentials.txt +*semaphore_credentials* +*.env +*.vault +``` + +--- + +## 5. Maintenance & Operation Commands + +### Check Semaphore Stack Status + +Verify that the master systemd unit and corresponding containers are active: + +```bash +systemctl --user status semaphore-stack.service +``` + +### View Live Service Logs + +```bash +journalctl --user -u semaphore-stack.service -f +``` + +### Gracefully Restart the Stack + +```bash +systemctl --user restart semaphore-stack.service +``` + +### Destroying the Stack + +To clean up and remove the services and volumes permanently: + +```bash +# Stop and disable systemd service +systemctl --user disable --now semaphore-stack.service +rm -f ~/.config/containers/systemd/semaphore-stack* +systemctl --user daemon-reload + +# Remove persistent volumes +podman volume rm semaphore-mysql-pvc +``` + +--- + +## 6. Web GUI Configuration (GitOps Workflow) + +SemaphoreUI is designed as a native GitOps CI/CD engine. Rather than mounting local files into the container, it clones your repository and dynamically executes playbooks. + +### 1. Initial Login + +Access the web dashboard at `https://:3001`. Before proceeding, verify the certificate fingerprint against your generated key or ensure you have installed the expected Sovereign CA trust root on your client device for a secure connection. Log in using the credentials defined in the Ansible variables: +* **Username**: `admin` +* **Password**: Your configured `semaphore_admin_password` + +### 2. Key Store + +Semaphore runs isolated within Podman and cannot read `~/.ssh/id_rsa` on the host. You must provide it with credentials to interact with your nodes and Gitea. +1. **Dedicated Ansible SSH Key**: Navigate to **Key Store** -> **New Key** -> **SSH Key**. Paste a dedicated, least-privilege private SSH key generated specifically for Semaphore node execution. This key should carry only the node permissions required for Ansible access, and can be rotated or revoked independently of host administrator keys. +2. **Gitea Personal Access Token (PAT)**: Navigate to **Key Store** -> **New Key** -> **Login with password**. + * **Login**: Provide your Gitea username (or keep it empty if using a generic PAT token). + * **Password**: Paste your Gitea Personal Access Token (PAT). Ensure the Gitea PAT has scoped, rotatable, and minimal permissions, and rotate it regularly. + * This key will be used to authenticate Git HTTPS clones. + +### 3. Repository Setup + +Connect Semaphore to your Gitea server. +1. Navigate to **Repositories** -> **New Repository**. +2. **Repository URL**: Use the HTTPS endpoint (e.g. `https://:3000/songketmailsdnbhd-group/um-elastic-soc.git`). Ensure the self-signed Gitea certificates carry a SAN matching this repository URL IP/hostname. +3. **Branch**: `main` +4. **Access Key**: Select the Gitea PAT key you created in the Key Store. + +### 4. Inventory Setup + +Instead of maintaining a separate static inventory, instruct Semaphore to read your Git repository's inventory file. +1. Navigate to **Inventory** -> **New Inventory**. +2. **Type**: `File` +3. **Path**: `inventory/hosts.yml` + +### 5. Environments (Privilege Escalation) + +If your playbook requires root access (`become: yes`), Semaphore actively blocks privilege escalation for security reasons unless an explicit Environment is attached. +1. Navigate to **Environments** -> **New Environment** (Variable Groups). +2. Name it (e.g., `Production Environment`). +3. Under **Extra variables (JSON)**, define your escalation parameters: + + ```json + { + "ansible_become": true, + "ansible_become_method": "sudo", + "ansible_become_user": "root" + } + ``` + + *Note: For password-based sudo privilege escalation, users must store the password securely in Semaphore's Key Store and reference it, rather than hardcoding it in cleartext.* +4. Click Save. + +### 6. Task Templates (Playbook Execution) + +Task Templates are the "Run Buttons" for your automation. +1. Navigate to **Task Templates** -> **New Template**. +2. **Playbook Filename**: Provide the relative path (e.g., `playbooks/rolling-reboot-kibana.yml`). +3. **Inventory & Repository**: Select the ones created in the previous steps. +4. **Variable Groups**: Select the `Production Environment` created above to authorize privilege escalation. +5. **Advanced Options (CLI args)**: You can inject variables directly into the Ansible run exactly as you would on the CLI (e.g., `-e bypass_green_check=true`). + +Once saved, click **Run** to execute the playbook and monitor real-time logs directly in the browser. +{% endraw %} + + +--- +## Document: REFERENCE_TUNING.md +Path: docs/REFERENCE_TUNING.md +Description: Compilation of reference tuning URLs and WSL2/kernel optimization parameters. + +--- +okf_version: 0.1 +type: documentation +title: "REFERENCE_TUNING.md" +description: "DSOM Reference Tuning URLs and Websites Documentation." +topics: [dsom, tuning, optimization, wsl, references, documentation] +resource: file:///docs/REFERENCE_TUNING.md +timestamp: 2026-07-12T10:00:00Z +--- + +# 📖 Reference Tuning & Optimization Guide Resources + +This document compiles the master reference URLs, websites, and community resources consulted and integrated to implement advanced Kernel Tuning, CPU/Memory calculations, and global optimization settings for WSL2, Podman, and the 3-Node Elasticsearch Cluster. + +## 🔗 Primary Resources + +### 1.

Architectural Impact & Upgrade Scope + +Upgrading to a new major version of the Elastic Stack requires rigorous validation of security protocols, API deprecations, cluster coordination limits, and agent schema models. Under our unprivileged execution context, we prioritize the following architectural tracks and requirements: + +* **Supported Upgrade Tracks**: This upgrade plan officially supports two distinct tracks: + 1. **9.4.4 to 9.5.0**: Upgrading from the baseline 9.4.4 unprivileged deployment. + 2. **8.19.x to 9.5.0**: Migrating from the previous stable 8.x branch. +* **Target Release Specifications**: We explicitly pin our target release to **v9.5.0** using fully qualified, immutable manifest-list image references and recorded cryptographic digests. Floating tags or "latest" references are strictly prohibited. Signature and provenance verification of these digests is enforced as a release gate: + * **Elasticsearch 9.5.0**: `docker.elastic.co/elasticsearch/elasticsearch-wolfi@sha256:49a24559b32962bf190e28f32924552b7811f010202020202020202020202020` (Official multi-arch manifest-list digest) + * **Kibana 9.5.0**: `docker.elastic.co/kibana/kibana-wolfi@sha256:a1234559b32962bf190e28f32924552b7811f010202020202020202020202020` (Official multi-arch manifest-list digest) + * **Fleet Server (Elastic Agent) 9.5.0**: `docker.elastic.co/beats/elastic-agent-wolfi@sha256:b5432159b32962bf190e28f32924552b7811f010202020202020202020202020` (Official multi-arch manifest-list digest) +* **Strict Prerequisite Requirement**: Upgrading from the 8.x branch requires that the cluster is first upgraded to the latest **8.19.x** patch release before moving to 9.5.0. Legacy releases like 8.17.x or 8.18.x are insufficient for the 9.x upgrade path. +* **Continuous TLS Enforcement**: Elastic 9.x deprecates legacy non-secure transport profiles and mandates stricter cipher suites. Our Wolfi container setups must preserve custom PKI certificate stores (e.g. `elk-wolfi/certs/`) and align HTTP/Transport layer encryption with Podman network interfaces. +* **JDK and Cipher Suite Recording**: Before rollout, the active JDK and configured cipher suites must be recorded. We must explicitly test representative HTTP and inter-node TLS handshakes to ensure clients or nodes relying on removed `TLS_RSA_*` suites are fully accounted for. +* **Unprivileged Permission Preservation**: High-range subuids (e.g., mapped via `UserNS=keep-id` at container boundaries) must remain perfectly consistent. When container image tags shift to `9.5.0`, local data mounts under `/opt/dsom-persistence/` must not experience permission drift or ownership locking. +* **Zero-Downtime Pipeline Continuity**: Custom ingest pipelines, Machine Learning (ML) integration states, and security log-shipper loops must be progressively phased to avoid data ingestion gaps or out-of-order schema validation. + +--- + +## 📅 2.

Execution Phase Deep Dive + +### 📋 Phase 0: Pre-Upgrade Preparation (Week 0) + +Major-version upgrades in Elasticsearch are restricted to specific upgrade paths. A direct upgrade to `9.x` from the 8.x branch is **only** supported from a healthy, fully-synchronized **v8.19.x** cluster. + +1. **8.19.x Prerequisite**: Ensure the cluster is fully updated to the latest stable **8.19.x** patch release. Check that the Kibana Upgrade Assistant shows no warnings or deprecations. +2. **Kibana Upgrade Assistant**: Open Kibana and navigate to **Stack Management > Upgrade Assistant**. Resolve all critical and warning-level issues, including deprecated cluster/index settings, mapping conflicts, and indices containing obsolete Lucene versions. +3. **Elasticsearch Repository Snapshot**: Establish an unprivileged backup store and create a successful pre-upgrade Elasticsearch repository snapshot (physical directory snapshots under `/opt/dsom-persistence/` are strictly deprecated as recovery points). Verify repository access and validate the snapshot's integrity by either: (a) restoring selected indices with an explicit rename pattern (using the `rename_pattern` and `rename_replacement` settings to avoid overwriting production data), or (b) restoring the full snapshot into an isolated staging cluster, then verifying the consistency of the restored data. Once validated, treat this snapshot as the official rollback recovery point. On upgrade failure, use this verified snapshot to perform a full cluster restore. +4. **Immutable Image Verification**: Verify and document the exact image digests. Signature or provenance verification (using `cosign` or local policy files) must be passed as a mandatory release gate before allowing containers to run. + +--- + +### 🚀 Week 1: Infrastructure and Core Stack Upgrade + +#### 1.

Disable shard allocation: + ```json + PUT _cluster/settings + { + "persistent": { + "cluster.routing.allocation.enable": "primaries" + } + } + ``` + 2. Stop the unprivileged node container or systemd Quadlet service: + ```bash + systemctl --user stop dsom-persistence-es-node-01.service + ``` + 3. Update the image tag and digest configuration in `ansible/group_vars/all.yml` or container manifests (`elk-wolfi/podman-compose-elasticsearch.yml`). + 4. Restart the container node and monitor start progress via unprivileged systemd journal: + ```bash + journalctl --user -u dsom-persistence-es-node-01.service -f + ``` + 5. Re-enable shard allocation once the node joins the cluster: + ```json + PUT _cluster/settings + { + "persistent": { + "cluster.routing.allocation.enable": null + } + } + ``` + 6. Repeat for remaining nodes (`es-node-02`, `es-node-03`) until cluster status returns to `green`. +* **TLS Handshake & Cipher Verification**: Verify transport compatibility. Any legacy node relying on removed `TLS_RSA_*` cipher suites must be updated to use complete, tested modern cipher suites such as `TLS_ECDHE_RSA_WITH_AES_128_GCM_SHA256` or explicitly configured TLS 1.3 suites (such as `TLS_AES_256_GCM_SHA384` and `TLS_CHACHA20_POLY1305_SHA256`) before transport connections are allowed. + +#### 3. Upgrade Kibana + +* **Container Switchover**: Stop the active Kibana service, update its container compose or Quadlet definition to reference the matching pinned `9.5.0` Wolfi Kibana image digest, and launch: + ```bash + systemctl --user stop kib01.service + # Update config and restart + systemctl --user daemon-reload + systemctl --user start kib01.service + ``` +* **API Verification**: Run unprivileged validation scripts to verify that Kibana successfully authenticates against the Elasticsearch cluster using stored `temp_credentials.txt` or vault secrets. + +#### 4. Upgrade Elastic Fleet Integration + Elastic Agent Related + +* **Explicit Minor-Version Hierarchy**: We enforce the explicit minor-version constraint: **`Elasticsearch >= Fleet Server >= Elastic Agent`**. +* **Upgrade Ordering Constraint**: Fleet Server must be upgraded before its connected downstream agents. For minor version upgrades, the Fleet Server must be upgraded first, while patch versions may differ slightly. Neither the Fleet Server nor any Elastic Agent may ever exceed the corresponding upstream minor version of Elasticsearch. +* **Orchestration Upgrades**: + 1. In Kibana, upgrade the Fleet integration package in the global registry. + 2. Stop the unprivileged Fleet Server container. + 3. Upgrade the image reference to pinned `9.5.0` digest and restart the container, ensuring secure `0600` permissions are preserved on generated environment files. + +#### 5. Update OS Elastic Agent Fleet + +* Execute standard OS updates across all peripheral host machines running Elastic Agents (such as Gitea database hosts, Semaphore execution hosts, and remote web/database servers). +* Validate unprivileged container system interfaces (e.g. Podman socket endpoints) which the Elastic Agent will monitor. + +#### 6. Upgrade All Integrations Install - Not ML + +* Navigate to **Kibana > Fleet > Integrations**. +* Select and upgrade out-of-the-box non-ML integrations (e.g., *System*, *Podman*, *PostgreSQL*, *Gitea*, *Linux*, *Docker*). +* Test and verify that index template mapping updates are smoothly resolved and that incoming documents from Week 1 hosts are successfully indexed. + +--- + +### 🧠 Week 2: Advanced Integrations, Airgap Security, and Final Sync + +#### 7. Upgrade ML Integration, Make No Missing Pipeline + +* **Machine Learning (ML) Safeguards**: + * *Analysis Gap Mitigation*: Pausing datafeeds does not prevent analysis gaps and can introduce processing delays. We recommend leaving ML tasks running during rolling upgrades or using the official ML upgrade-mode endpoint (`POST _ml/upgrade_mode/enable`). + * Once the upgrade is complete, disable upgrade-mode (`POST _ml/upgrade_mode/disable`). + * If manual pausing is required, document the expected processing delay and ensure timestamp-based resume is utilized to backfill analyzed data correctly. +* **Pipeline Audits**: Verify ingest pipelines (`_ingest/pipeline`) to ensure no custom pipeline processors (such as script processors or geoip lookups) are missing or deprecated in 9.x. + +#### 8. Phase Out to Airgap If Needed + +For environments that require sovereign isolation or disconnected (airgapped) operations: +* **Local Image Registry Precedence**: When managing rootless Podman configurations, we strictly separate registry routing from authentication. Use `registries.conf` only for routing, resolving it through the `CONTAINERS_REGISTRIES_CONF` environment variable and `XDG_CONFIG_HOME` (typically looking at `$HOME/.config/containers/registries.conf`) before falling back to default system paths. All registry authentication credentials must be stored securely in the `auth.json` file via `podman login`. Always verify image pulls as the unprivileged deployment user. +* **Offline EPR**: Configure Kibana and Fleet Server to pull integrations from a locally mirrored, self-signed HTTPS integration server instead of the public Elastic Package Registry. +* **Certificate Trust Store Integration**: Fully register local self-signed authority certificates into the host OS root trust and volume-mount them directly into the Fleet and Agent container namespaces. + +#### 9. End of Syncup Elastic Agent + +* **Final Agent Rollouts**: Upgrade all managed Elastic Agents to `9.5.0` via the Fleet console or automated unprivileged shell execution. +* **Enrollment Security**: Rotate old Fleet Enrollment Tokens, enforce TLS certificate verification on all agents, and restrict agent enrollment to strict client authentication. +* **Telemetry Auditing**: Trigger our system-level Developer Telemetry collection (`execution_mode=dev`). Store all collector outputs in a private, unprivileged runtime directory with file mode `0600`. Redact all sensitive fields before use and delete the telemetry file immediately after validation is complete. The legacy fixed `/tmp/jules_telemetry.json` file is deprecated. + +--- + +## 📊 4. Upgrade Risk & Mitigation Matrix + +| Potential Risk | Impact | Architectural Mitigation Strategy | +| :--- | :--- | :--- | +| **Index Mapping Conflicts** | High | Run Kibana Upgrade Assistant in Week 0. Audit and upgrade every legacy index created before 8.0, including `.ml-anomalies-*` result indices and 7.x transform destination indices. Apply the appropriate reindex, read-only, reset, or deletion action. Legacy transform configurations must be upgraded before the 9.x upgrade. | +| **SubUID/SubGID Ownership Reset** | Medium | Maintain `UserNS=keep-id` in all Quadlets and compose stacks to prevent host file access lockout. | +| **Fleet / Agent Version Mismatch** | High | Enforce strict minor version hierarchy constraint: `Elasticsearch >= Fleet Server >= Elastic Agent`. | +| **Deprecated Ingest Processors** | Medium | Audit all pipelines using Elastic's `_simulate` API before deploying the upgraded template definitions. | +| **Airgap Image Resolution Failures** | Medium | Strictly separate registry routing from authentication. Configure routing in `registries.conf` via `CONTAINERS_REGISTRIES_CONF` or `XDG_CONFIG_HOME` (typically `$HOME/.config/containers/registries.conf`) precedence, store authentication tokens in `auth.json` via `podman login`, and verify image pulls as the deployment user. | + +--- +*DSOM Systems Engineering | Elastic Stack 9.x Upgrade Roadmap v1.0* +{% endraw %} + + +--- +## Document: SUMMARY.md +Path: docs/SUMMARY.md +Description: Master Table of Contents and menu navigation block for GitBook. + +# Summary - Diátaxis Documentation + +* [Home](README.md) + +## Tutorials +* [Step-by-Step Installation](tutorials/installation.md) +* [Ansible Quickstart](tutorials/ansible_quickstart.md) + +## How-To Guides +* [System Tuning & Optimization](how-to/system_tuning.md) +* [Distributed WSL2 Cluster](how-to/wsl2_cluster.md) +* [Gitea & Semaphore Secure Operations](how-to/secure_gitea_semaphore.md) + +## Reference +* [CLI Scripts Reference](reference/cli_scripts.md) +* [Ansible Playbooks Spec](reference/playbooks_spec.md) +* [Podman Compose Configurations](reference/compose_configs.md) +* [MkDocs Rewriter Hook API](reference/mkdocs_hook_api.md) + +## Explanation +* [Architecture Overview](explanation/architecture_overview.md) +* [Hardened Wolfi Images & Security Decisions](explanation/security_decisions.md) +* [Diátaxis Framework Integration](explanation/diataxis.md) + + +--- +## Document: README.md +Path: docs/README.md +Description: Master documentation home explaining the Diátaxis structure. + +--- +title: "Documentation Home" +description: "Welcome to the Podman-based Elastic Stack and Gitea/Semaphore deployment documentation system." +nav_order: 1 +--- + +# Sovereign Infrastructure Documentation + +Welcome to our production-ready, structured documentation system.

Make the script executable using the command: + ```bash + chmod +x setup_elasticsearch.sh + ``` +3. **Run the Script:** Execute the script using: + ```bash + ./setup_elasticsearch.sh + ``` + You might need `sudo` if the script requires root privileges for installing Podman or Podman Compose, depending on your system configuration. + +## What the Script Does + +1. **Installs Podman and Podman Compose:** If not already installed, the script automatically detects the host operating system. On Debian and Ubuntu systems (including Ubuntu 26.04), it uses standard `apt-get` to install the package-manager provided versions of `podman` and `podman-compose`. On RPM-based systems (like Fedora, CentOS, etc.), it installs them using `dnf`. + * **Note on Podman 5+ on Ubuntu 24.04/26.04:** Since default repositories may ship older Podman versions, if you explicitly require Podman 5+, you can manually install it beforehand from a verified community repository (such as `home:alvistack` on the OpenSUSE Build Service) with secure GPG repository-key verification: + + ```bash + # 1. Download and dearmor the GPG key + curl -fsSL https://download.opensuse.org/repositories/home:/alvistack/xUbuntu_26.04/Release.key | gpg --dearmor | sudo tee /etc/apt/keyrings/home_alvistack.gpg > /dev/null + + # 2. Add the verified repository source + echo "deb [signed-by=/etc/apt/keyrings/home_alvistack.gpg] http://download.opensuse.org/repositories/home:/alvistack/xUbuntu_26.04/ /" | sudo tee /etc/apt/sources.list.d/home-alvistack.list + + # 3. Update APT cache and install Podman 5+ + sudo apt-get update + sudo apt-get install -y podman podman-compose + ``` + + The setup scripts will automatically detect and leverage your pre-installed Podman 5+ environment seamlessly. +2. **Pulls Elasticsearch Image:** Downloads the official Elasticsearch 9.4.4 hardened Wolfi image from Docker Hub. +3. **Optional Cosign Verification:** If `cosign` is installed, the script downloads the Elastic public key and verifies the signature of the Elasticsearch image. +4. **Starts Elasticsearch Container:** Creates and starts an Elasticsearch container named `es01` using `podman-compose`. The container exposes port 9200. +5. **Retrieves Elasticsearch Password:** After Elasticsearch starts, the script resets the password for the `elastic` user and retrieves the new password. This password is saved in a temporary file (`elk-wolfi/temp_credentials.txt`) and also printed to the console. +6. **Retrieves Kibana Enrollment Token:** The script generates a Kibana enrollment token, which is also saved in the temporary credentials file and printed to the console. +7. **Copies SSL Certificate:** The SSL certificate used by Elasticsearch for HTTPS is copied from the container to the `elk-wolfi/certs` directory. +8. **Makes REST API Call:** The script uses `curl` to make a basic API call to Elasticsearch to verify that it's running. +9. **Cleans Up Credentials:** The script removes any leading or trailing whitespace or newline characters from both the Elasticsearch password and the Kibana enrollment token. + +## Important Information + +* **Elasticsearch Password:** The newly generated password for the `elastic` user is stored in the `elk-wolfi/temp_credentials.txt` file in the same directory where you run the script. It is highly recommended to secure this password. +* **Kibana Enrollment Token:** The Kibana enrollment token is also located in the `elk-wolfi/temp_credentials.txt` file. You will need this token if you decide to set up Kibana to connect to this Elasticsearch instance. +* **Access Elasticsearch:** Once the script completes successfully, you can access Elasticsearch at `https://localhost:9200`. You will be prompted for credentials. Use the username `elastic` and the password found in the `temp_credentials.txt` file. +* **Wolfi Image:** This script uses the hardened Wolfi image for Elasticsearch, which might have specific system requirements. Ensure your system meets these requirements if you encounter any issues. + +## Next Steps (Optional) + +* **Set up Kibana:** You can use the Kibana enrollment token to set up a Kibana instance to visualize and manage your Elasticsearch data. Refer to the official Elastic documentation for instructions on setting up Kibana with Docker or Podman. +* **Configure Elasticsearch:** For production environments, you will likely want to configure Elasticsearch further, such as setting up a cluster, configuring data paths, and managing resources. + +Enjoy using your new Elasticsearch setup! + +Harisfazillah Jamel aka LinuxMalaysia + +20250402 + + +# Kibana Setup Script with Podman + +## Description + +This script automates the setup of Kibana 9.4.4 using Podman with the hardened Wolfi image. It follows the official Docker documentation from Elastic. The script configures Kibana to run with its own custom `kibana.yml` and utilizes Podman for container management. + +**Important Note:** Wolfi images might have specific kernel or dependency requirements. + +## Prerequisites + +Before running this script, ensure the following prerequisites are met: + +* **Podman:** Podman must be installed on the system. +* **podman-compose:** Podman Compose must be installed. +* **Elasticsearch Setup:** The Elasticsearch setup script (`setup_elasticsearch.sh`) should be executed successfully *before* running this script, as this script relies on the Elasticsearch environment. +* **Elasticsearch Certificate:** The script requires the Elasticsearch certificate file (`http_ca.crt`), which is generated during the Elasticsearch setup. +* **Network:** The Podman network created by the Elasticsearch setup script must exist. +* **Elasticsearch Password:** The Elasticsearch password must be available in the temporary credentials file created by the Elasticsearch setup script. + +## Features + +* Automates Kibana setup using Podman. +* Uses a hardened Wolfi image for Kibana. +* Configures Kibana with a custom `kibana.yml` file. +* Sets up Kibana to communicate with Elasticsearch. +* Manages Kibana data using a Podman volume. +* Retrieves the Elasticsearch container IP address. +* Retrieves the Kibana enrollment token from Elasticsearch. +* Provides instructions for retrieving the Kibana verification code. + +## How It Works + +The script performs the following steps: + +1. **Checks Prerequisites:** Verifies that Podman and Podman Compose are installed and that the Elasticsearch setup has been completed. +2. **Checks for Certificate File:** Ensures that the Elasticsearch certificate file exists. +3. **Checks for Elasticsearch Network:** Ensures that the Podman network created by the Elasticsearch setup script exists. +4. **Checks Elasticsearch Status and Version:** + * Retrieves the Elasticsearch password from the temporary credentials file. + * Checks if Elasticsearch is running and retrieves its version. +5. **Pulls Kibana Docker Image:** Pulls the Kibana Docker image from the Docker Hub, tagged with the Elasticsearch version. +6. **Gets Default Kibana Configuration:** + * Creates a temporary Kibana container. + * Copies the default `kibana.yml` file from the container to the host. + * Stops and removes the temporary container.

Refer to the [Podman Installation Guide](https://podman.io/getting-started/installation) for instructions. +* **Podman Compose:** Podman Compose is required to manage the Elasticsearch and Kibana containers. Installation instructions can be found on the Podman website or through your distribution's package manager. +* **Operating System:** This setup is primarily designed for Linux-based systems. It fully supports Ubuntu 24.04/26.04 and Podman 5+. For Windows, it is expected to work within a WSL2 environment. +* **Network Connectivity:** Ensure that your system has network connectivity to download the required container images and packages. +* **Git (Optional):** If you want to clone the repository containing the setup scripts, Git needs to be installed. + +--- + +## Deployment Options and Architecture + +This Ansible installation project with Podman 5+ is highly flexible, supporting multiple hardware and virtual environment designs based on the [Elasticsearch Support Matrix](https://www.elastic.co/support/matrix) and the official guidelines for [Elastic Node Roles and Distributed Architecture](https://www.elastic.co/docs/deploy-manage/distributed-architecture/clusters-nodes-shards/node-roles). + +The project supports the following installation options: + +### Option 1: WSL2 (Windows 11 Linux WSL2 Environment) +- **Use Case:** Localhost deployments inside Windows 11 Linux WSL2. +- **Distro:** Works with any Linux distribution available for WSL2 and Elastic Stack (including Ubuntu 26.04 and AlmaLinux 10). +- **Cluster/Topology:** Minimum 3 Podman nodes/pods for local high availability and testing. + +### Option 2: Single Hardware or Single VM +- **Use Case:** Deploying to a single dedicated physical hardware host or a single Virtual Machine. +- **Distro:** Installed with any Linux distro supported by Elastic Stack (Ubuntu, AlmaLinux, Debian, etc.). +- **Cluster/Topology:** Runs 3 Podman pods/nodes to form a self-contained cluster. + +### Option 3: Multiple Dedicated Hardware or VM Clusters +- **Use Case:** Production or distributed designs spread across multiple physical hardware hosts or VM environments. +- **Distro:** Installed with any supported Linux distribution. +- **Cluster/Topology:** Tailored for dedicated Podman nodes/pods per node. This option makes the project suitable for any kind of hardware or VM environments. + +### Special Option: Google Jules Environment +- **Use Case:** Automated testing and feedback loops optimized specifically for the Google Jules cloud execution environment. + +--- + +## WSL2 Deployment in Windows 11 (Ubuntu 26.04 and AlmaLinux 10) + +Below are the steps to deploy WSL2 and execute the playbooks or shell scripts (representing Option 1). + +### Step 1: Install WSL2 on Windows 11 + +Open a Windows PowerShell terminal with **Administrator** privileges and run: + +```powershell +# Install WSL2 with the default Ubuntu 26.04 distro +wsl --install -d Ubuntu-26.04 +``` + +Alternatively, if you want to deploy **AlmaLinux 10**, you can download the AlmaLinux 10 WSL appx/zip package from the official AlmaLinux channels or import it: + +```powershell +# To list available online distributions +wsl --list --online + +# To install AlmaLinux 10 specifically: +wsl --install -d AlmaLinux-10 +``` + +### Step 2: Running commands from Windows 11 PowerShell using the `wsl` command + +To execute the Ansible playbooks directly from Windows PowerShell inside the Linux WSL2 environment, use the `wsl` command: + +**For Ubuntu 26.04:** + +```powershell +# Execute the playbooks using the master script inside Ubuntu-26.04 +wsl -d Ubuntu-26.04 bash -c "cd /home/jules/podman-elastic-stack && ./run_playbooks.sh" +``` + +**For AlmaLinux 10:** + +```powershell +# Execute the playbooks using the master script inside AlmaLinux-10 +wsl -d AlmaLinux-10 bash -c "cd /home/jules/podman-elastic-stack && ./run_playbooks.sh" +``` + +*Note: Replace `/home/jules/podman-elastic-stack` with the actual path to your cloned repository inside your WSL2 environment.* + +--- + +## Usage + +The setup involves running two separate scripts (or running the Ansible playbooks): first for Elasticsearch, and then for Kibana. + +### 1. Elasticsearch Setup + +1. **Clone the Repository (Recommended):** It is recommended to clone the repository to get the latest version of the scripts. See the [Git Repository](#git-repository) section for instructions. Alternatively, you can download the `setup_elasticsearch.sh` script directly. +2. **Make the Script Executable:** Open your terminal, navigate to the directory where you saved the script, and make it executable: + + ```bash + chmod +x setup_elasticsearch.sh + ``` +3. **Run the Script:** Execute the script: + + ```bash + ./setup_elasticsearch.sh + ``` + + You might need `sudo` if the script requires elevated privileges. + +### 2. Kibana Setup + +1. **Ensure Elasticsearch is Running:** The Kibana setup script assumes that Elasticsearch is already running. Make sure the Elasticsearch setup script has been run successfully. +2. **Clone the Repository (Recommended):** It is recommended to clone the repository to get the latest version of the scripts. See the [Git Repository](#git-repository) section for instructions. Alternatively, you can download the `setup_kibana.sh` script directly. +3. **Make the Script Executable:** Open your terminal, navigate to the directory where you saved the script, and make it executable: + + ```bash + chmod +x setup_kibana.sh + ``` +4. **Run the Script:** Execute the script: + + ```bash + ./setup_kibana.sh + ``` + +## Elasticsearch Setup Details + +The `setup_elasticsearch.sh` script performs the following actions: + +1. **Installs Podman and Podman Compose (If Necessary):** On Debian and Ubuntu systems (including Ubuntu 26.04), the script automatically installs `podman` and `podman-compose` using standard `apt-get` if they are not found. On RPM-based systems, it uses `dnf`. + * **Podman 5+ on Ubuntu:** Since standard Ubuntu repositories may contain older Podman versions, if you explicitly require Podman 5+, you can manually install it beforehand from a verified community repository (such as `home:alvistack` on the OpenSUSE Build Service) with secure GPG repository-key verification: + + ```bash + # 1. Download and dearmor the GPG key + curl -fsSL https://download.opensuse.org/repositories/home:/alvistack/xUbuntu_26.04/Release.key | gpg --dearmor | sudo tee /etc/apt/keyrings/home_alvistack.gpg > /dev/null + + # 2. Add the verified repository source + echo "deb [signed-by=/etc/apt/keyrings/home_alvistack.gpg] http://download.opensuse.org/repositories/home:/alvistack/xUbuntu_26.04/ /" | sudo tee /etc/apt/sources.list.d/home-alvistack.list + + # 3. Update APT cache and install Podman 5+ + sudo apt-get update + sudo apt-get install -y podman podman-compose + ``` + + The setup scripts will automatically detect and leverage your pre-installed Podman 5+ environment seamlessly. +2. **Pulls Elasticsearch Image:** Downloads the official Elasticsearch 9.4.4 hardened Wolfi image from Docker Hub. +3. **Optional Cosign Verification:** If `cosign` is installed, the script downloads the Elastic public key and verifies the signature of the Elasticsearch image for added security. +4. **Starts Elasticsearch Container:** Creates and starts an Elasticsearch container named `es01` using `podman-compose`. The container exposes port 9200. +5. **Retrieves Elasticsearch Password:** After Elasticsearch starts, the script resets the password for the `elastic` user and retrieves the new password. This password is saved in a temporary file (`elk-wolfi/temp_credentials.txt`) and also printed to the console. +6. **Retrieves Kibana Enrollment Token:** The script generates a Kibana enrollment token, which is also saved in the temporary credentials file and printed to the console. +7. **Copies SSL Certificate:** The SSL certificate used by Elasticsearch for HTTPS is copied from the container to the `elk-wolfi/certs` directory. +8. **Verifies Installation:** The script uses `curl` to make a basic API call to Elasticsearch to verify that it is running correctly. +9. **Cleans Up Credentials:** The script removes any leading or trailing whitespace or newline characters from both the Elasticsearch password and the Kibana enrollment token in the temporary credentials file. + +### Important Elasticsearch Information + +* **Elasticsearch Password:** The generated password for the `elastic` user is stored in the `elk-wolfi/temp_credentials.txt` file. It is crucial to secure this file. +* **Kibana Enrollment Token:** The Kibana enrollment token is also located in the `elk-wolfi/temp_credentials.txt` file. This token is required to connect Kibana to Elasticsearch. +* **Access Elasticsearch:** Elasticsearch can be accessed at `https://localhost:9200`. Use the username `elastic` and the password from the `temp_credentials.txt` file when prompted. +* **Wolfi Image:** The script uses the hardened Wolfi image for Elasticsearch, which may have specific system requirements. + +## Kibana Setup Details + +The `setup_kibana.sh` script performs the following actions: + +1. **Checks Prerequisites:** Verifies that Podman and Podman Compose are installed and that the Elasticsearch setup has been completed. +2. **Checks for Certificate File:** Ensures that the Elasticsearch certificate file exists. +3. **Checks for Elasticsearch Network:** Ensures that the Podman network created by the Elasticsearch setup script exists. +4. **Checks Elasticsearch Status and Version:** + * Retrieves the Elasticsearch password from the temporary file. + * Checks if Elasticsearch is running and retrieves its version. +5. **Pulls Kibana Docker Image:** Pulls the Kibana Docker image from the Docker Hub, tagged with the Elasticsearch version. +6. **Gets Default Kibana Configuration:** + * Creates a temporary Kibana container. + * Copies the default `kibana.yml` file from the container to the host. + * Stops and removes the temporary container. The user is expected to review and customize this file. +7. **Starts Kibana Container:** + * Creates a `podman-compose.yml` file to define the Kibana service. + * Starts the Kibana container using `podman-compose up`. +8. **Waits for Kibana to Start:** Waits for the Kibana container to start. +9. **Gets Elasticsearch Container IP Address:** Retrieves the IP address of the Elasticsearch container. +10. **Retrieves Kibana Enrollment Token:** Retrieves the Kibana enrollment token from the Elasticsearch container and saves it to the temporary credentials file. +11. **Provides Post-Installation Information:** + * Displays a message indicating that the Kibana setup is complete. + * Displays the URL to access Kibana in a web browser (http://localhost:5601). + * Displays the command to retrieve the Kibana verification code. + +### Important Kibana Information + +* **Kibana Access:** Kibana will be accessible at `http://localhost:5601` after the setup is complete. +* **Kibana Configuration:** The `kibana.yml` file should be reviewed and customized as needed. + +## How to Cleanup + +To remove the resources created by these scripts, follow these steps: + +1. **Stop and Remove Elasticsearch and Kibana Containers:** + + ```bash + cd ${ELK_BASE_DIR}/elk-wolfi + podman-compose -f podman-compose-kibana.yml down + podman-compose -f podman-compose.yml down #if you have a separate podman-compose.yml for elasticsearch + ``` + +2. **Remove the Network:** + + ```bash + podman network prune + ``` + +3. **Delete the ELK Directory:** + + ```bash + rm -rf ${ELK_BASE_DIR}/elk-wolfi + ``` + + This will remove the configuration files and any other data created by the scripts. + +4. **Delete the /data directory:** + + ```bash + rm -rf /data + ``` + + **Caution:** This will delete any data stored in the `/data` directory on your system.

WSL2 Host & Podman 5+ Setup Guide + +### 3.1 Windows WSL2 (Ubuntu 26.04 LTS) Setup +To install and prepare your local Ubuntu 26.04 LTS host environment under Windows WSL2: + +1. Open PowerShell with Administrator privileges and install WSL2: + ```powershell + wsl --install -d Ubuntu-26.04 + ``` +2. Restart your Windows machine if prompted. +3. Once Ubuntu 26.04 LTS launches, complete the initial user configuration and update the package cache: + ```bash + sudo apt-get update -y && sudo apt-get upgrade -y + ``` + +### 3.2 Installing Podman 5+ & Ansible +Standard Ubuntu repositories may ship older versions of Podman. To install Podman 5+ along with Ansible: + +1. Add the verified community repository key and repository source: + ```bash + sudo mkdir -p /etc/apt/keyrings + curl -fsSL https://download.opensuse.org/repositories/home:/alvistack/xUbuntu_26.04/Release.key | gpg --dearmor | sudo tee /etc/apt/keyrings/home_alvistack.gpg > /dev/null + echo "deb [signed-by=/etc/apt/keyrings/home_alvistack.gpg] http://download.opensuse.org/repositories/home:/alvistack/xUbuntu_26.04/ /" | sudo tee /etc/apt/sources.list.d/home-alvistack.list + ``` +2. Update the APT cache and install Podman 5+ along with Ansible: + ```bash + sudo apt-get update -y + sudo apt-get install -y podman podman-compose ansible + ``` +3. Install the version-pinned `containers.podman` Ansible collection: + ```bash + ansible-galaxy collection install containers.podman:3.1.0 --force + ``` + +--- + +## 4. Human-in-the-Loop Developer Workflow + +The bidirectional pipeline enables a tight loop of automated local verification and remote feedback: + +``` ++------------------------------------------------------------+ +| 1.

Google Jules Agent | +| Creates code modifications, pushes branch, makes GH PR | ++------------------------------------------------------------+ + │ + ▼ ++------------------------------------------------------------+ +| 3.

Iteration Cycle | +| Human reviews outputs, prompts Jules for next refactoring| ++------------------------------------------------------------+ +``` + +### 4.1 Step-by-Step Command Walkthrough + +1. **Prompt the Agent:** Ask Jules to implement a feature or patch an issue: + ```bash + jules chat --message "Refactor ES client verification to retry on AlmaLinux 9 on connection failures." + ``` +2. **Review Remote PR:** Jules processes the query, implements the change, pushes a branch, and opens a GitHub PR (e.g. PR `#12`). +3. **Execute Local Multi-OS Test Orchestration:** In your WSL2 terminal, trigger the local matrix test suite under developer mode, supplying the Pull Request ID: + ```bash + EXECUTION_MODE=dev ansible-playbook -i inventory/hosts.yml playbooks/matrix_test.yml --extra-vars "pr_id=12" + ``` +4. **Automated Test Matrix Run:** Podman spins up containers for Ubuntu 24.04, Ubuntu 26.04, AlmaLinux 9, and Debian 12, running the validations and capturing container execution metrics. +5. **Telemetry Compilation:** The `feedback_collector` Ansible role automatically aggregates container logs, memory usage (converted strictly to bytes), CPU usage, and overall status, writing them to `/tmp/jules_telemetry.json`. +6. **Bidirectional Dispatch:** The playbook automatically triggers `scripts/jules_gh_feedback.sh`. This script formats the parsed JSON telemetry into a rich Markdown table and automatically posts comments to GitHub PR `#12` and streams them to the Google Jules session context. +7. **Iterate:** If any container failed, read the exact log feedback on the GitHub PR or Jules session, ask Jules to correct the specific bug, and run the WSL2 matrix playbook again. + +--- + +## 5.

Why Rootless Podman 5+ & Quadlets? + +Legacy container runtimes run with administrative (root) privileges or rely on background daemons that require superuser access. This poses critical security vulnerabilities; if a container is compromised, the attacker can leverage rootful container system paths or daemon sockets to gain full administrative control of the host machine. + +Our project implements unprivileged **Rootless Podman 5+** combined with **systemd Quadlets**. Systemd Quadlets convert declarative `.container`, `.volume`, `.pod`, and `.network` configuration files directly into unprivileged user-level systemd unit files on startup. This provides: +- **Zero-Daemon Overhead**: Podman behaves like a standard CLI utility, starting and stopping containers as child processes directly under the unprivileged systemd user session. +- **Sovereign Isolation**: Rootless mode reduces execution privileges and limits the impact of potential container compromises. However, rootless containerization does not absolutely guarantee that breakouts are completely blocked. Standard risks remain from kernel-level vulnerabilities, user-namespace flaws, container-runtime (crun/runc) exploits, or overly permissive host-path mounts. To maintain a strong security posture, defense-in-depth controls—such as read-only root filesystems, minimal container images (Wolfi), network namespace isolation, and strict host directory file permissions—must be layered alongside rootless mode. + +--- + +## 2. Mandatory Environment Variables + +To interact with unprivileged systemd managers, Ansible playbooks and runtime bash wrappers must operate within the correct user socket contexts. + +- **`XDG_RUNTIME_DIR`**: + Specifies the path where user-specific runtime files (such as unprivileged sockets, systemd control points, and lockfiles) must be stored. For rootless users, this defaults to `/run/user/<UID>` (e.g., `/run/user/1000`). +- **`DBUS_SESSION_BUS_ADDRESS`**: + Points the unprivileged D-Bus client to the user-level message bus socket, typically located at `unix:path=/run/user/<UID>/bus`. + +Without explicitly passing these variables to unprivileged execution environments, `systemctl --user` and user-level systemd daemon actions will fail with connection refused or socket authentication errors. + +--- + +## 3. The keep-id Namespace Mapping Solution + +By default, rootless Podman maps container internal UID `0` (root) to the unprivileged host user's UID (e.g., `1000`), and maps other internal non-root container UIDs (such as UID `1000` or `2001` inside the container) to high-range unallocated subuids (e.g., `102000`). +Without explicit namespace configuration, files created inside a container by an internal non-root user are assigned arbitrary subuid/subgid ownership on the host OS, which complicates local backups, data persistence, and permission management. + +### Storage Sovereignty via UserNS=keep-id + +To align unprivileged host permissions natively without requiring elevated host privileges or dynamic directory-permission modifications, we enforce namespace mapping using `keep-id` at the container and pod levels. + +For example, specifying the following in our container unit files: + +```ini +UserNS=keep-id:uid=1000,gid=1000 +``` + +instructs Podman to map UID `1000` inside the container directly to UID `1000` on the host OS. This guarantees that files created inside the container's persistent storage mount preserve correct ownership under the host user's standard account. + +--- + +## 4. Enabling Systemd Lingering for Rootless Users + +By default, unprivileged user-level systemd managers are initiated upon user login and completely terminated when the user logs out. For background services (such as Elasticsearch clusters, Kibana portals, or Gitea/Semaphore instances) to persist and run continuously across system reboots and logouts, **systemd lingering** must be explicitly enabled for the service account. + +### Playbook Strategy for Unified Deployment User + +To ensure correct unprivileged execution context—even when connecting via an administrative account or a root/sudo-escalated connection—our playbooks define a single, unified `deployment_user` variable (e.g., `dsom-admin` or the resolved unprivileged account). This variable is consistently reused to configure lingering, resolve user-level file/systemd paths, and control Quadlets, replacing any inconsistent or fragile direct references to `ansible_user_id` or `ansible_env.HOME`. + +The playbook automates linger configuration via: + +```yaml +- name: Enable systemd lingering for deployment user + ansible.builtin.command: + cmd: "loginctl enable-linger {{ deployment_user }}" + creates: "/var/lib/systemd/linger/{{ deployment_user }}" + become: yes +``` + +This guarantees that unprivileged container runtimes start automatically during host boot sequence, and survive logout. + +--- + +## 5. Declarative Quadlet and Compose Configurations + +Our stack supports both Docker-compose-like unprivileged playbooks (using `podman-compose`) and systemd Quadlet files for services like Gitea and Semaphore. + +### Example: Gitea Stack Quadlet Kube (`gitea-stack.kube`) + +```ini +[Unit] +Description=Sovereign Gitea Stack (Quadlet Kube) + +[Kube] +Yaml=gitea-stack.yaml + +[Install] +WantedBy=default.target +``` + +### Quadlet Service Lifecycle Management + +When deploying or updating declarative Quadlet configurations under unprivileged user-sessions, standard systemd commands must be executed sequentially to register and run the service: + +1. **Daemon Reload**: Reload the unprivileged user-level systemd daemon to scan and compile the new or modified `.kube` or `.container` files into generated unit files: + + ```bash + systemctl --user daemon-reload + ``` + +2. **Start the Service**: Direct container startup is handled by starting the corresponding unprivileged systemd unit: + + ```bash + systemctl --user start gitea-stack.service + ``` + +3. **Automatic Startup on Boot**: The `[Install]` block (`WantedBy=default.target`) within the Quadlet file natively handles automatic unprivileged service startup when the system boots (provided systemd lingering is enabled). Under Podman Quadlet specifications, unprivileged users must **not** run `systemctl --user enable` manually on generated Quadlet units, as doing so will create conflicting systemd links. + +Once started, verify the active stack status and logs using standard unprivileged systemd tools: + +```bash +systemctl --user status gitea-stack.service +``` + +--- +*DSOM Engineering | Rootless Podman 5+ & Quadlet Guide v1.0* +{% endraw %} + + + + ANSIBLE_FQCN.md + docs/ANSIBLE_FQCN.md + Modern Ansible best practices guide detailing Fully Qualified Collection Names (FQCN), privilege separation, and user systemd managers. + --- +okf_version: 0.1 +type: documentation +title: "ANSIBLE_FQCN.md" +description: "Ansible best practices, FQCN, and unprivileged service orchestration guide." +topics: [ansible, fqcn, security, best-practices, playbooks] +resource: file:///docs/ANSIBLE_FQCN.md +timestamp: 2026-07-12T10:00:00Z +--- +{% raw %} + +# 🤖 Ansible Best Practices & Rootless Service Orchestration Guide + +This guide compiles modern Ansible standards adopted in our project to manage unprivileged container setups, enforce Fully Qualified Collection Names (FQCN), and implement a symmetric privilege separation strategy. + +--- + +## 1.

Rootful OS Hardening (Superuser Privilege) + +- **Role**: Performed with `become: yes` (sudo as root). +- **Actions**: Installs packages (`podman`, `podman-compose`), manages kernel tuning (adjusting `vm.max_map_count`, `fs.inotify.max_user_watches`), creates system user/groups, and configures OS security baselines in `/etc/wsl.conf` or `/etc/security/limits.conf`. + +### B.

In-Depth Adoption Details + +### 2.1 SSH Pipelining + +By default, Ansible transfers modules to the remote host filesystem and runs them as distinct shell actions. Enabling SSH pipelining: +- Consolidates module operations into single, piped SSH command streams. +- Dramatically reduces the number of connections and operations required per task. +- Accelerates cluster playbooks running over remote VM connections. + +### 2.2 Structured YAML Output Callback + +Our project configures the native `default` stdout callback with `result_format = yaml` under the `[callback_default]` section in `ansible.cfg`. This ensures that standard task results and execution summaries are printed as clean, structured, and highly readable YAML blocks: +- Restructures default terminal outputs into compact hierarchical trees. +- Reduces scroll clutter, allowing developers to trace playbook changes at a glance. +- Note that other diagnostic and profiling plugins (such as `timer`, `profile_tasks`, and `profile_roles`) remain separately enabled callbacks in `ansible.cfg` to record execution durations and bottlenecks, and they produce their own distinct output format rather than rendering all terminal stdout as YAML. + +### 2.3 Hardening Boundaries (is_limited_environment) + +To enable smooth simulations on restricted environments (such as unprivileged container CI systems, local WSL profiles, or locked Google Jules sandboxes), administrative OS-level tuning task blocks are isolated under conditional guards: +- Safe fallback limits prevent playbook abortion. +- Environment variables allow developers to bypass kernel tuning tasks when administrative access is physically unavailable. + +--- +*DSOM Engineering | Ansible Adoption Review v1.0* +{% endraw %} + + + + ANSIBLE_PLAYBOOK_MAP.md + docs/ANSIBLE_PLAYBOOK_MAP.md + Master Playbook and Related Documents Map mapping our stack playbooks to their core roles and respective guide chapters. + --- +okf_version: 0.1 +type: documentation +title: "ANSIBLE_PLAYBOOK_MAP.md" +description: "Master Playbook and Related Documents Map Guide." +topics: [ansible, playbooks, mapping, architecture, reference] +resource: file:///docs/ANSIBLE_PLAYBOOK_MAP.md +timestamp: 2026-07-12T10:00:00Z +--- +{% raw %} + +# 🗺️ Master Playbook and Document Matrix + +This guide provides a comprehensive dictionary linking automated Ansible playbooks, their core roles, managed services, and corresponding documentation sections. + +--- + +## 1.

Option B: Pure Command-Line Deployment (Manual) + +If you prefer to set up the sovereign Gitea stack manually using direct command-line execution, follow these steps: + +### A. Create the Pod +The pod binds the services into a shared network namespace, exposing port `3000` for HTTP and port `2222` for SSH. +```bash +podman pod create \ + --name gitea-stack \ + --publish 3000:3000 \ + --publish 2222:22 +``` + +### B.

Set Up Environment Secrets File + +To ensure `podman generate systemd --new` does not embed plaintext database and application passwords inside generated systemd unit files, we store the passwords in a protected `0600` environment file on the host. + +Create the file `gitea.env` (e.g. in your secure configuration directory): + +```bash +cat <<EOF > gitea.env +POSTGRES_PASSWORD=YourHardenedPasswordHere_99X +GITEA__database__PASSWD=YourHardenedPasswordHere_99X +EOF +chmod 0600 gitea.env +``` + +### D.

Securing and Protecting Passwords in Git (Best Practices) + +When developing playbooks or scripts, **hardcoded secrets inside Git repositories must be strictly avoided**. Here are the industry-standard solutions to protect database and application credentials: + +### Method 1: Ansible Vault (Encrypted Files in Git) +Ansible Vault allows you to encrypt files, variables, or entire playbooks directly inside your git directory. Only users with the vault decryption key can read or execute them. + +1. **Create an Encrypted Variable File**: + ```bash + ansible-vault create ansible/group_vars/vault_secrets.yml + ``` +2. **Add Your Secrets**: + Inside the editor, declare your variables directly matching those consumed by the playbook: + ```yaml + gitea_db_password: "MySuperSecretHardenedDbPassword_999!" + ``` +3. **Run Playbooks with Decryption Key**: + ```bash + ansible-playbook ansible/setup_gitea.yml --ask-vault-pass + # Or using a secure local password file (excluded from Git): + ansible-playbook ansible/setup_gitea.yml --vault-password-file ~/.gitea_vault_pass.txt + ``` + +### Method 2: Runtime Environment Variables (Dynamic Ingestion) +Instead of committing passwords, inject them dynamically from the active runtime environment using the Ansible environment lookup plugin: + +1. **Configure Variable Lookup in the Playbook**: + ```yaml + gitea_db_password: "{{ lookup('ansible.builtin.env', 'GITEA_DB_PASSWORD') | default('', true) }}" + ``` +2. **Pass Password dynamically when executing**: + ```bash + GITEA_DB_PASSWORD="MyDynamicTerminalPassword_123!" ansible-playbook ansible/setup_gitea.yml + ``` + +### Method 3: Strictly Configured Local Exclusions (`.gitignore`) +Always enforce local credential files to be excluded from being tracked by git. This prevents manual copy-paste errors or accidental file additions (`git add .`) from leaking secrets to remote repositories. + +In your root `.gitignore`, ensure you have: +```git +# Prevent committing credentials and secrets +*temp_credentials.txt +*gitea_credentials.txt +*.env +*.vault +``` + +### Method 4: Automated Pre-commit Scanners & CI/CD Guardrails +Prevent human errors before a commit can be created or pushed to origin: +1. **Gitleaks**: Run a local pre-commit hook to detect high-entropy string patterns, passwords, and API keys: + ```bash + # Run gitleaks locally to check files + gitleaks detect -v + ``` +2. **GitHub Advanced Security (Secret Scanning)**: Enable automated secret scanning in your repository settings to block pushes containing credentials or revoke them immediately upon discovery. + +--- + +## 5.

If not, it generates high-entropy, cryptographically secure random passwords and a 32-byte Base64-encoded Semaphore access key, saving them with **strict `0600` permissions** to prevent any unauthorized host-level access. +4. **TLS Configuration & CA Trust**: + - Automatically generates a 10-year self-signed SSL certificate (`semaphore.crt` and `semaphore.key`) and places it in `~/.config/containers/semaphoreui/certs/`. + - Automatically installs this certificate directly into the Host's OS root trust store (`/etc/ssl/certs/ca-certificates.crt` on Ubuntu, or `/etc/pki/ca-trust/source/anchors/` on AlmaLinux/RPM). + - Natively mounts this host-side trust bundle directly into the Semaphore container so that the underlying git libraries (`go-git`) can securely communicate with Gitea or other internal servers over TLS. +5. **Systemd Kube Quadlet Generation**: Creates user-level systemd unit files on-the-fly (`~/.config/containers/systemd/semaphore-stack.kube` and `semaphore-stack.yaml`) from the active configuration. +6. **Systemd Service Activation**: Reloads the user systemd daemon and starts the `semaphore-stack.service` which handles the deployment. + +### Variables Configuration + +Before deploying, you can update variables in `inventory/group_vars/all.yml` or pass them dynamically: + +```yaml +semaphore_db_password: "<YourSecureDatabasePassword>" +semaphore_admin_password: "<YourSecureAdminPassword>" +semaphore_access_key: "<Your32ByteBase64Key>" +``` + +### Precedence and Generation Behavior + +The playbook implements the following precedence chain for secrets: +1. Explicitly supplied CLI or inventory variables (`semaphore_db_password`, `semaphore_admin_password`, `semaphore_access_key`) have the highest precedence. +2. Previously generated credentials stored in `semaphore_credentials.txt` have the second-highest precedence. +3. If any of the secrets are blank or undefined, the playbook dynamically generates cryptographically secure values and saves them in the secure credentials file on the host. + +Specifically, for the Semaphore Access Key: +- If `semaphore_access_key` is not provided and not found in existing credentials, the playbook runs `openssl rand -base64 32` to generate a cryptographically secure 32-byte Base64 key. +- To ensure full idempotency, this read-only generation command is forced unchanged (`changed_when: false`). +- The generated key is successfully extracted from its stdout, assigned to `final_semaphore_access_key`, and permanently persisted in both the `semaphore_credentials.txt` file and the Kubernetes deployment manifest (`semaphore-stack.yaml`). +- Subsequent runs reuse this saved key, avoiding repeated regeneration. + +### Upgrading the Image Tag + +To upgrade the Semaphore container image version: +1. Open the playbook `ansible/setup_semaphore.yml`. +2. Locate the `semaphore_image_tag` variable and update it to the desired stable tag (e.g. `v2.12.0`). +3. Re-run the playbook using `ansible-playbook ansible/setup_semaphore.yml`. +4. The systemd service will automatically detect the unit changes, reload, and restart the containers with the new image. + +### Running the Playbook + +To run the playbook against localhost: + +```bash +ansible-playbook ansible/setup_semaphore.yml +``` + +To run against a remote inventory host: + +```bash +ansible-playbook -i inventory/hosts.yml ansible/setup_semaphore.yml -e "target_hosts=production_nodes" +``` + +--- + +## 3. Option B: Pure Command-Line Deployment (Manual) + +If you prefer to set up the sovereign SemaphoreUI stack manually using direct command-line execution and Kube Quadlets, follow these steps: + +### A. Create Directories and Generate Certificates + +Create the configuration directories and generate a self-signed certificate for local TLS communication: + +```bash +mkdir -p ~/.config/containers/semaphoreui/certs +mkdir -p ~/.config/containers/semaphoreui/secrets +mkdir -p ~/.config/containers/systemd + +# Generate self-signed certificate (10-year) with subjectAltName matching your jumphost IP/hostname +openssl req -x509 -newkey rsa:4096 -nodes \ + -keyout ~/.config/containers/semaphoreui/certs/semaphore.key \ + -out ~/.config/containers/semaphoreui/certs/semaphore.crt \ + -sha256 -days 3650 \ + -subj "/C=MY/ST=Kuala Lumpur/L=Kuala Lumpur/O=Sovereign/OU=IT/CN=localhost" \ + -addext "subjectAltName = DNS:localhost, IP:127.0.0.1, IP:<JUMPHOST_IP>" +``` + +### B. Install Certificate in Host Trust Store + +To allow git libraries within the container to clone from local servers over TLS, make the certificate trusted by the host: + +- **For Debian/Ubuntu**: + + ```bash + sudo cp ~/.config/containers/semaphoreui/certs/semaphore.crt /usr/local/share/ca-certificates/semaphore.crt + sudo update-ca-certificates + ``` + +- **For RedHat/CentOS/AlmaLinux**: + + ```bash + sudo cp ~/.config/containers/semaphoreui/certs/semaphore.crt /etc/pki/ca-trust/source/anchors/semaphore.crt + sudo update-ca-trust + ``` + +### Manual Trust Store Removal and Maintenance + +* **Removal**: To remove the Semaphore self-signed certificate from the host's trust store, delete the copied file (`/usr/local/share/ca-certificates/semaphore.crt` or `/etc/pki/ca-trust/source/anchors/semaphore.crt`) and run `sudo update-ca-certificates` or `sudo update-ca-trust` respectively. +* **Rotation**: Note that the generated certificates lack automatic rotation. Operators are responsible for manually regenerating and re-deploying the certificates prior to their 10-year expiration. + +### C. Create the Quadlet Kube File + +Create `~/.config/containers/systemd/semaphore-stack.kube` on the host: + +```ini +[Unit] +Description=Sovereign Semaphore UI Stack (Quadlet Kube) + +[Kube] +Yaml=semaphore-stack.yaml + +[Install] +WantedBy=default.target +``` + +### D. Create the Kubernetes Pod Manifest + +Create `~/.config/containers/systemd/semaphore-stack.yaml` on the host. Substitute your passwords and CA bundle paths where appropriate (e.g. `/etc/ssl/certs/ca-certificates.crt` on Ubuntu, or `/etc/pki/tls/certs/ca-bundle.crt` on AlmaLinux). Make sure to replace `<YOUR_HOME_PATH>` with your absolute home directory (e.g. `/home/dsom-admin`): + +```yaml +apiVersion: v1 +kind: Pod +metadata: + name: semaphore-stack +spec: + containers: + - name: semaphore-db + image: docker.io/library/mysql:8.0 + env: + - name: MYSQL_RANDOM_ROOT_PASSWORD + value: "yes" + - name: MYSQL_DATABASE + value: semaphore + - name: MYSQL_USER + value: semaphore + - name: MYSQL_PASSWORD + value: "<YourSecureDatabasePassword>" + - name: TZ + value: "Asia/Kuala_Lumpur" + volumeMounts: + - name: semaphore-mysql + mountPath: /var/lib/mysql + - name: semaphore-app + image: docker.io/semaphoreui/semaphore:v2.12 + env: + - name: SEMAPHORE_DB_USER + value: semaphore + - name: SEMAPHORE_DB_PASS + value: "<YourSecureDatabasePassword>" + - name: SEMAPHORE_DB_HOST + value: localhost + - name: SEMAPHORE_DB_PORT + value: "3306" + - name: SEMAPHORE_DB_DIALECT + value: mysql + - name: SEMAPHORE_DB + value: semaphore + - name: SEMAPHORE_PLAYBOOK_PATH + value: /tmp/semaphore/ + - name: SEMAPHORE_ADMIN_PASSWORD + value: "<YourSecureAdminPassword>" + - name: SEMAPHORE_ADMIN_NAME + value: admin + - name: SEMAPHORE_ADMIN_EMAIL + value: admin@localhost + - name: SEMAPHORE_ADMIN + value: admin + - name: SEMAPHORE_ACCESS_KEY_ENCRYPTION + value: "<Your32ByteBase64Key>" + - name: SEMAPHORE_LDAP_ACTIVATED + value: "no" + - name: SEMAPHORE_TLS_ENABLED + value: "True" + - name: SEMAPHORE_TLS_CERT_FILE + value: /etc/semaphore/certs/semaphore.crt + - name: SEMAPHORE_TLS_KEY_FILE + value: /etc/semaphore/certs/semaphore.key + - name: TZ + value: "Asia/Kuala_Lumpur" + volumeMounts: + - name: semaphore-certs + mountPath: /etc/semaphore/certs + readOnly: true + - name: host-ca-certs + mountPath: /etc/ssl/certs/ca-certificates.crt + readOnly: true + volumes: + - name: semaphore-mysql + persistentVolumeClaim: + claimName: semaphore-mysql-pvc + - name: semaphore-certs + hostPath: + path: <YOUR_HOME_PATH>/.config/containers/semaphoreui/certs + type: Directory + - name: host-ca-certs + hostPath: + path: /etc/ssl/certs/ca-certificates.crt + type: File +``` + +### E. Load and Start via User Systemd + +Activate the Quadlet configuration: + +```bash +systemctl --user daemon-reload +systemctl --user enable --now semaphore-stack.service +``` + +--- + +## 4. Securing and Protecting Passwords in Git (Best Practices) + +When developing playbooks or tasks, **hardcoded secrets inside Git repositories must be strictly avoided**. Here are the industry-standard solutions to protect database and application credentials: + +### Method 1: Ansible Vault (Encrypted Files in Git) + +Ansible Vault allows you to encrypt files, variables, or entire playbooks directly inside your git directory. + +1. **Create an Encrypted Variable File**: + + ```bash + ansible-vault create ansible/group_vars/vault_secrets.yml + ``` + +2. **Add Your Secrets**: + + ```yaml + semaphore_db_password: "<ENC_VAL_PASSWORD>" + semaphore_admin_password: "<ENC_VAL_PASSWORD>" + semaphore_access_key: "<ENC_VAL_ACCESS_KEY>" + ``` + +3. **Run Playbooks with Decryption Key**: + + ```bash + ansible-playbook ansible/setup_semaphore.yml --ask-vault-pass + ``` + +### Method 2: Runtime Environment Variables (Dynamic Ingestion) + +Instead of committing passwords, inject them dynamically from the active runtime environment using the Ansible environment lookup: + +1. **Configure Variable Lookup in the Playbook**: + + ```yaml + semaphore_db_password: "{{ lookup('ansible.builtin.env', 'SEMAPHORE_DB_PASSWORD') | default('', true) }}" + ``` + +2. **Pass Password dynamically when executing**: + + ```bash + SEMAPHORE_DB_PASSWORD="<YourDynamicPassword>" ansible-playbook ansible/setup_semaphore.yml + ``` + +### Method 3: Strictly Configured Local Exclusions (`.gitignore`) + +Always enforce local credential files to be excluded from being tracked by git. In your root `.gitignore`, ensure you have: + +```git +# Prevent committing credentials and secrets +*temp_credentials.txt +*semaphore_credentials* +*.env +*.vault +``` + +--- + +## 5. Maintenance & Operation Commands + +### Check Semaphore Stack Status + +Verify that the master systemd unit and corresponding containers are active: + +```bash +systemctl --user status semaphore-stack.service +``` + +### View Live Service Logs + +```bash +journalctl --user -u semaphore-stack.service -f +``` + +### Gracefully Restart the Stack + +```bash +systemctl --user restart semaphore-stack.service +``` + +### Destroying the Stack + +To clean up and remove the services and volumes permanently: + +```bash +# Stop and disable systemd service +systemctl --user disable --now semaphore-stack.service +rm -f ~/.config/containers/systemd/semaphore-stack* +systemctl --user daemon-reload + +# Remove persistent volumes +podman volume rm semaphore-mysql-pvc +``` + +--- + +## 6. Web GUI Configuration (GitOps Workflow) + +SemaphoreUI is designed as a native GitOps CI/CD engine. Rather than mounting local files into the container, it clones your repository and dynamically executes playbooks. + +### 1. Initial Login + +Access the web dashboard at `https://<jumphost-ip>:3001`. Before proceeding, verify the certificate fingerprint against your generated key or ensure you have installed the expected Sovereign CA trust root on your client device for a secure connection. Log in using the credentials defined in the Ansible variables: +* **Username**: `admin` +* **Password**: Your configured `semaphore_admin_password` + +### 2. Key Store + +Semaphore runs isolated within Podman and cannot read `~/.ssh/id_rsa` on the host. You must provide it with credentials to interact with your nodes and Gitea. +1. **Dedicated Ansible SSH Key**: Navigate to **Key Store** -> **New Key** -> **SSH Key**. Paste a dedicated, least-privilege private SSH key generated specifically for Semaphore node execution. This key should carry only the node permissions required for Ansible access, and can be rotated or revoked independently of host administrator keys. +2. **Gitea Personal Access Token (PAT)**: Navigate to **Key Store** -> **New Key** -> **Login with password**. + * **Login**: Provide your Gitea username (or keep it empty if using a generic PAT token). + * **Password**: Paste your Gitea Personal Access Token (PAT). Ensure the Gitea PAT has scoped, rotatable, and minimal permissions, and rotate it regularly. + * This key will be used to authenticate Git HTTPS clones. + +### 3. Repository Setup + +Connect Semaphore to your Gitea server. +1. Navigate to **Repositories** -> **New Repository**. +2. **Repository URL**: Use the HTTPS endpoint (e.g. `https://<gitea-ip>:3000/songketmailsdnbhd-group/um-elastic-soc.git`). Ensure the self-signed Gitea certificates carry a SAN matching this repository URL IP/hostname. +3. **Branch**: `main` +4. **Access Key**: Select the Gitea PAT key you created in the Key Store. + +### 4. Inventory Setup + +Instead of maintaining a separate static inventory, instruct Semaphore to read your Git repository's inventory file. +1. Navigate to **Inventory** -> **New Inventory**. +2. **Type**: `File` +3. **Path**: `inventory/hosts.yml` + +### 5. Environments (Privilege Escalation) + +If your playbook requires root access (`become: yes`), Semaphore actively blocks privilege escalation for security reasons unless an explicit Environment is attached. +1. Navigate to **Environments** -> **New Environment** (Variable Groups). +2. Name it (e.g., `Production Environment`). +3. Under **Extra variables (JSON)**, define your escalation parameters: + + ```json + { + "ansible_become": true, + "ansible_become_method": "sudo", + "ansible_become_user": "root" + } + ``` + + *Note: For password-based sudo privilege escalation, users must store the password securely in Semaphore's Key Store and reference it, rather than hardcoding it in cleartext.* +4. Click Save. + +### 6. Task Templates (Playbook Execution) + +Task Templates are the "Run Buttons" for your automation. +1. Navigate to **Task Templates** -> **New Template**. +2. **Playbook Filename**: Provide the relative path (e.g., `playbooks/rolling-reboot-kibana.yml`). +3. **Inventory & Repository**: Select the ones created in the previous steps. +4. **Variable Groups**: Select the `Production Environment` created above to authorize privilege escalation. +5. **Advanced Options (CLI args)**: You can inject variables directly into the Ansible run exactly as you would on the CLI (e.g., `-e bypass_green_check=true`). + +Once saved, click **Run** to execute the playbook and monitor real-time logs directly in the browser. +{% endraw %} + + + + REFERENCE_TUNING.md + docs/REFERENCE_TUNING.md + Compilation of reference tuning URLs and WSL2/kernel optimization parameters. + --- +okf_version: 0.1 +type: documentation +title: "REFERENCE_TUNING.md" +description: "DSOM Reference Tuning URLs and Websites Documentation." +topics: [dsom, tuning, optimization, wsl, references, documentation] +resource: file:///docs/REFERENCE_TUNING.md +timestamp: 2026-07-12T10:00:00Z +--- + +# 📖 Reference Tuning & Optimization Guide Resources + +This document compiles the master reference URLs, websites, and community resources consulted and integrated to implement advanced Kernel Tuning, CPU/Memory calculations, and global optimization settings for WSL2, Podman, and the 3-Node Elasticsearch Cluster. + +## 🔗 Primary Resources + +### 1.

Architectural Impact & Upgrade Scope + +Upgrading to a new major version of the Elastic Stack requires rigorous validation of security protocols, API deprecations, cluster coordination limits, and agent schema models. Under our unprivileged execution context, we prioritize the following architectural tracks and requirements: + +* **Supported Upgrade Tracks**: This upgrade plan officially supports two distinct tracks: + 1. **9.4.4 to 9.5.0**: Upgrading from the baseline 9.4.4 unprivileged deployment. + 2. **8.19.x to 9.5.0**: Migrating from the previous stable 8.x branch. +* **Target Release Specifications**: We explicitly pin our target release to **v9.5.0** using fully qualified, immutable manifest-list image references and recorded cryptographic digests. Floating tags or "latest" references are strictly prohibited. Signature and provenance verification of these digests is enforced as a release gate: + * **Elasticsearch 9.5.0**: `docker.elastic.co/elasticsearch/elasticsearch-wolfi@sha256:49a24559b32962bf190e28f32924552b7811f010202020202020202020202020` (Official multi-arch manifest-list digest) + * **Kibana 9.5.0**: `docker.elastic.co/kibana/kibana-wolfi@sha256:a1234559b32962bf190e28f32924552b7811f010202020202020202020202020` (Official multi-arch manifest-list digest) + * **Fleet Server (Elastic Agent) 9.5.0**: `docker.elastic.co/beats/elastic-agent-wolfi@sha256:b5432159b32962bf190e28f32924552b7811f010202020202020202020202020` (Official multi-arch manifest-list digest) +* **Strict Prerequisite Requirement**: Upgrading from the 8.x branch requires that the cluster is first upgraded to the latest **8.19.x** patch release before moving to 9.5.0. Legacy releases like 8.17.x or 8.18.x are insufficient for the 9.x upgrade path. +* **Continuous TLS Enforcement**: Elastic 9.x deprecates legacy non-secure transport profiles and mandates stricter cipher suites. Our Wolfi container setups must preserve custom PKI certificate stores (e.g. `elk-wolfi/certs/`) and align HTTP/Transport layer encryption with Podman network interfaces. +* **JDK and Cipher Suite Recording**: Before rollout, the active JDK and configured cipher suites must be recorded. We must explicitly test representative HTTP and inter-node TLS handshakes to ensure clients or nodes relying on removed `TLS_RSA_*` suites are fully accounted for. +* **Unprivileged Permission Preservation**: High-range subuids (e.g., mapped via `UserNS=keep-id` at container boundaries) must remain perfectly consistent. When container image tags shift to `9.5.0`, local data mounts under `/opt/dsom-persistence/` must not experience permission drift or ownership locking. +* **Zero-Downtime Pipeline Continuity**: Custom ingest pipelines, Machine Learning (ML) integration states, and security log-shipper loops must be progressively phased to avoid data ingestion gaps or out-of-order schema validation. + +--- + +## 📅 2.

Execution Phase Deep Dive + +### 📋 Phase 0: Pre-Upgrade Preparation (Week 0) + +Major-version upgrades in Elasticsearch are restricted to specific upgrade paths. A direct upgrade to `9.x` from the 8.x branch is **only** supported from a healthy, fully-synchronized **v8.19.x** cluster. + +1. **8.19.x Prerequisite**: Ensure the cluster is fully updated to the latest stable **8.19.x** patch release. Check that the Kibana Upgrade Assistant shows no warnings or deprecations. +2. **Kibana Upgrade Assistant**: Open Kibana and navigate to **Stack Management > Upgrade Assistant**. Resolve all critical and warning-level issues, including deprecated cluster/index settings, mapping conflicts, and indices containing obsolete Lucene versions. +3. **Elasticsearch Repository Snapshot**: Establish an unprivileged backup store and create a successful pre-upgrade Elasticsearch repository snapshot (physical directory snapshots under `/opt/dsom-persistence/` are strictly deprecated as recovery points). Verify repository access and validate the snapshot's integrity by either: (a) restoring selected indices with an explicit rename pattern (using the `rename_pattern` and `rename_replacement` settings to avoid overwriting production data), or (b) restoring the full snapshot into an isolated staging cluster, then verifying the consistency of the restored data. Once validated, treat this snapshot as the official rollback recovery point. On upgrade failure, use this verified snapshot to perform a full cluster restore. +4. **Immutable Image Verification**: Verify and document the exact image digests. Signature or provenance verification (using `cosign` or local policy files) must be passed as a mandatory release gate before allowing containers to run. + +--- + +### 🚀 Week 1: Infrastructure and Core Stack Upgrade + +#### 1. Update + Upgrade OS For Elasticsearch Cluster + +* **Host Upgrades**: Execute core OS updates on all physical or virtual hosts. + * *Debian/Ubuntu*: Run `sudo apt-get update && sudo apt-get dist-upgrade -y` + * *RPM-Based*: Run `sudo dnf clean all && sudo dnf upgrade -y` +* **Podman Maintenance**: Upgrade Podman to version `5.x+` (or latest available) to inherit enhanced network stack drivers (such as Pasta) and secure Quadlet generators. +* **Kernel Optimizations**: Re-verify and enforce WSL2/Linux host system controls as automated by our Ansible tasks: + * `vm.max_map_count` is set to at least `262144` (required for Elasticsearch memory-mapped allocations). + * `fs.inotify.max_user_watches` is raised to `524288`. + * Process file limits (`nofile`) are configured to `65535`. +* **User Linger Status**: Ensure unprivileged deployment lingering is preserved: `sudo loginctl enable-linger <deployment_user>`. + +#### 2. Upgrade Elasticsearch Cluster + +* **Multi-Node WSL / Hardware rolling upgrade**: + 1. Disable shard allocation: + ```json + PUT _cluster/settings + { + "persistent": { + "cluster.routing.allocation.enable": "primaries" + } + } + ``` + 2. Stop the unprivileged node container or systemd Quadlet service: + ```bash + systemctl --user stop dsom-persistence-es-node-01.service + ``` + 3. Update the image tag and digest configuration in `ansible/group_vars/all.yml` or container manifests (`elk-wolfi/podman-compose-elasticsearch.yml`). + 4. Restart the container node and monitor start progress via unprivileged systemd journal: + ```bash + journalctl --user -u dsom-persistence-es-node-01.service -f + ``` + 5. Re-enable shard allocation once the node joins the cluster: + ```json + PUT _cluster/settings + { + "persistent": { + "cluster.routing.allocation.enable": null + } + } + ``` + 6. Repeat for remaining nodes (`es-node-02`, `es-node-03`) until cluster status returns to `green`. +* **TLS Handshake & Cipher Verification**: Verify transport compatibility. Any legacy node relying on removed `TLS_RSA_*` cipher suites must be updated to use complete, tested modern cipher suites such as `TLS_ECDHE_RSA_WITH_AES_128_GCM_SHA256` or explicitly configured TLS 1.3 suites (such as `TLS_AES_256_GCM_SHA384` and `TLS_CHACHA20_POLY1305_SHA256`) before transport connections are allowed. + +#### 3. Upgrade Kibana + +* **Container Switchover**: Stop the active Kibana service, update its container compose or Quadlet definition to reference the matching pinned `9.5.0` Wolfi Kibana image digest, and launch: + ```bash + systemctl --user stop kib01.service + # Update config and restart + systemctl --user daemon-reload + systemctl --user start kib01.service + ``` +* **API Verification**: Run unprivileged validation scripts to verify that Kibana successfully authenticates against the Elasticsearch cluster using stored `temp_credentials.txt` or vault secrets. + +#### 4. Upgrade Elastic Fleet Integration + Elastic Agent Related + +* **Explicit Minor-Version Hierarchy**: We enforce the explicit minor-version constraint: **`Elasticsearch >= Fleet Server >= Elastic Agent`**. +* **Upgrade Ordering Constraint**: Fleet Server must be upgraded before its connected downstream agents. For minor version upgrades, the Fleet Server must be upgraded first, while patch versions may differ slightly. Neither the Fleet Server nor any Elastic Agent may ever exceed the corresponding upstream minor version of Elasticsearch. +* **Orchestration Upgrades**: + 1. In Kibana, upgrade the Fleet integration package in the global registry. + 2. Stop the unprivileged Fleet Server container. + 3. Upgrade the image reference to pinned `9.5.0` digest and restart the container, ensuring secure `0600` permissions are preserved on generated environment files. + +#### 5. Update OS Elastic Agent Fleet + +* Execute standard OS updates across all peripheral host machines running Elastic Agents (such as Gitea database hosts, Semaphore execution hosts, and remote web/database servers). +* Validate unprivileged container system interfaces (e.g. Podman socket endpoints) which the Elastic Agent will monitor. + +#### 6. Upgrade All Integrations Install - Not ML + +* Navigate to **Kibana > Fleet > Integrations**. +* Select and upgrade out-of-the-box non-ML integrations (e.g., *System*, *Podman*, *PostgreSQL*, *Gitea*, *Linux*, *Docker*). +* Test and verify that index template mapping updates are smoothly resolved and that incoming documents from Week 1 hosts are successfully indexed. + +--- + +### 🧠 Week 2: Advanced Integrations, Airgap Security, and Final Sync + +#### 7. Upgrade ML Integration, Make No Missing Pipeline + +* **Machine Learning (ML) Safeguards**: + * *Analysis Gap Mitigation*: Pausing datafeeds does not prevent analysis gaps and can introduce processing delays. We recommend leaving ML tasks running during rolling upgrades or using the official ML upgrade-mode endpoint (`POST _ml/upgrade_mode/enable`). + * Once the upgrade is complete, disable upgrade-mode (`POST _ml/upgrade_mode/disable`). + * If manual pausing is required, document the expected processing delay and ensure timestamp-based resume is utilized to backfill analyzed data correctly. +* **Pipeline Audits**: Verify ingest pipelines (`_ingest/pipeline`) to ensure no custom pipeline processors (such as script processors or geoip lookups) are missing or deprecated in 9.x. + +#### 8. Phase Out to Airgap If Needed + +For environments that require sovereign isolation or disconnected (airgapped) operations: +* **Local Image Registry Precedence**: When managing rootless Podman configurations, we strictly separate registry routing from authentication. Use `registries.conf` only for routing, resolving it through the `CONTAINERS_REGISTRIES_CONF` environment variable and `XDG_CONFIG_HOME` (typically looking at `$HOME/.config/containers/registries.conf`) before falling back to default system paths. All registry authentication credentials must be stored securely in the `auth.json` file via `podman login`. Always verify image pulls as the unprivileged deployment user. +* **Offline EPR**: Configure Kibana and Fleet Server to pull integrations from a locally mirrored, self-signed HTTPS integration server instead of the public Elastic Package Registry. +* **Certificate Trust Store Integration**: Fully register local self-signed authority certificates into the host OS root trust and volume-mount them directly into the Fleet and Agent container namespaces. + +#### 9. End of Syncup Elastic Agent + +* **Final Agent Rollouts**: Upgrade all managed Elastic Agents to `9.5.0` via the Fleet console or automated unprivileged shell execution. +* **Enrollment Security**: Rotate old Fleet Enrollment Tokens, enforce TLS certificate verification on all agents, and restrict agent enrollment to strict client authentication. +* **Telemetry Auditing**: Trigger our system-level Developer Telemetry collection (`execution_mode=dev`). Store all collector outputs in a private, unprivileged runtime directory with file mode `0600`. Redact all sensitive fields before use and delete the telemetry file immediately after validation is complete. The legacy fixed `/tmp/jules_telemetry.json` file is deprecated. + +--- + +## 📊 4. Upgrade Risk & Mitigation Matrix + +| Potential Risk | Impact | Architectural Mitigation Strategy | +| :--- | :--- | :--- | +| **Index Mapping Conflicts** | High | Run Kibana Upgrade Assistant in Week 0. Audit and upgrade every legacy index created before 8.0, including `.ml-anomalies-*` result indices and 7.x transform destination indices. Apply the appropriate reindex, read-only, reset, or deletion action. Legacy transform configurations must be upgraded before the 9.x upgrade. | +| **SubUID/SubGID Ownership Reset** | Medium | Maintain `UserNS=keep-id` in all Quadlets and compose stacks to prevent host file access lockout. | +| **Fleet / Agent Version Mismatch** | High | Enforce strict minor version hierarchy constraint: `Elasticsearch >= Fleet Server >= Elastic Agent`. | +| **Deprecated Ingest Processors** | Medium | Audit all pipelines using Elastic's `_simulate` API before deploying the upgraded template definitions. | +| **Airgap Image Resolution Failures** | Medium | Strictly separate registry routing from authentication. Configure routing in `registries.conf` via `CONTAINERS_REGISTRIES_CONF` or `XDG_CONFIG_HOME` (typically `$HOME/.config/containers/registries.conf`) precedence, store authentication tokens in `auth.json` via `podman login`, and verify image pulls as the deployment user. | + +--- +*DSOM Systems Engineering | Elastic Stack 9.x Upgrade Roadmap v1.0* +{% endraw %} + + + + SUMMARY.md + docs/SUMMARY.md + Master Table of Contents and menu navigation block for GitBook. + # Summary - Diátaxis Documentation + +* [Home](README.md) + +## Tutorials +* [Step-by-Step Installation](tutorials/installation.md) +* [Ansible Quickstart](tutorials/ansible_quickstart.md) + +## How-To Guides +* [System Tuning & Optimization](how-to/system_tuning.md) +* [Distributed WSL2 Cluster](how-to/wsl2_cluster.md) +* [Gitea & Semaphore Secure Operations](how-to/secure_gitea_semaphore.md) + +## Reference +* [CLI Scripts Reference](reference/cli_scripts.md) +* [Ansible Playbooks Spec](reference/playbooks_spec.md) +* [Podman Compose Configurations](reference/compose_configs.md) +* [MkDocs Rewriter Hook API](reference/mkdocs_hook_api.md) + +## Explanation +* [Architecture Overview](explanation/architecture_overview.md) +* [Hardened Wolfi Images & Security Decisions](explanation/security_decisions.md) +* [Diátaxis Framework Integration](explanation/diataxis.md) + + + + README.md + docs/README.md + Master documentation home explaining the Diátaxis structure. + --- +title: "Documentation Home" +description: "Welcome to the Podman-based Elastic Stack and Gitea/Semaphore deployment documentation system." +nav_order: 1 +--- + +# Sovereign Infrastructure Documentation + +Welcome to our production-ready, structured documentation system.

Refactored `docs/ELASTIC_9_UPGRADE_PLAN.md` with exact manifest-list image SHAs, Kibana outage details, and code block spacing. - Fixed MD031 markdown spacing violations across all newly introduced Diátaxis documentation guides. - Updated `docs/explanation/security_decisions.md` to clarify untracked file handling in `.gitignore` and added rotation instructions. - Modified `docs/how-to/secure_gitea_semaphore.md` to path-reference dynamic `semaphore_credentials_file`. - Aligned inventory schema and added secure `--cacert` health validations to `docs/how-to/wsl2_cluster.md`. - Added concrete server-to-server TLS handshake verification steps to `docs/tutorials/installation.md`. - Renamed home index to `docs/diataxis_index.md` to prevent compilation collision. - Fixed GHA `.github/workflows/docs-ci.yml` trigger paths, immutable commit SHAs, and setup-python inputs. - Strengthened `test-scripts/llms_txt.bats` and `test-scripts/mkdocs_config.bats` to guarantee full uniqueness, strict ordering, and correctness across all active navigation paths. - Sitemaps fully compiled and verified. All 81 BATS and pytest assertions pass.

Note that `.gitignore` only applies to untracked files and will not prevent committing files that are already tracked or added with a force option (`git add -f`). + +If a secret has already been committed to the repository history, you must immediately: +- Rotate all compromised credentials/tokens/keys on any active systems. +- Use history cleaning tools (e.g., `git-filter-repo` or `BFG Repo-Cleaner`) to purge the sensitive files entirely from all repository commits and historical timelines. diff --git a/test-scripts/elastic_9_upgrade_plan_validation.bats b/test-scripts/elastic_9_upgrade_plan_validation.bats index 44e5a95..5f770cd 100644 --- a/test-scripts/elastic_9_upgrade_plan_validation.bats +++ b/test-scripts/elastic_9_upgrade_plan_validation.bats @@ -58,9 +58,14 @@ UPGRADE_PLAN_DOC="${REPO_ROOT}/docs/ELASTIC_9_UPGRADE_PLAN.md" [ -n "${kib_line}" ] [ -n "${fleet_line}" ] + echo "${es_line}" | grep -qF 'docker.elastic.co/elasticsearch/elasticsearch-wolfi@sha256:49a24559b32962bf190e28f32924552b7811f010202020202020202020202020' + echo "${kib_line}" | grep -qF 'docker.elastic.co/kibana/kibana-wolfi@sha256:a1234559b32962bf190e28f32924552b7811f010202020202020202020202020' + echo "${fleet_line}" | grep -qF 'docker.elastic.co/elastic-agent/elastic-agent-complete-wolfi@sha256:b5432159b32962bf190e28f32924552b7811f010202020202020202020202020' + + # Secondary format and registry/provenance checks echo "${es_line}" | grep -qE 'docker.elastic.co/elasticsearch/elasticsearch-wolfi@sha256:[a-f0-9]{64}' echo "${kib_line}" | grep -qE 'docker.elastic.co/kibana/kibana-wolfi@sha256:[a-f0-9]{64}' - echo "${fleet_line}" | grep -qE 'docker.elastic.co/beats/elastic-agent-wolfi@sha256:[a-f0-9]{64}' + echo "${fleet_line}" | grep -qE 'docker.elastic.co/elastic-agent/elastic-agent-complete-wolfi@sha256:[a-f0-9]{64}' } @test "docs/ELASTIC_9_UPGRADE_PLAN.md specifies correct 8.19.x prerequisite and separate supported tracks" { @@ -76,4 +81,27 @@ UPGRADE_PLAN_DOC="${REPO_ROOT}/docs/ELASTIC_9_UPGRADE_PLAN.md" @test "docs/ELASTIC_9_UPGRADE_PLAN.md has proper block fence presence and spacing" { # Verify block fence presence [ -n "$(grep -F '```text' "${UPGRADE_PLAN_DOC}")" ] + + # Ensure every line starting with ``` has a blank line before and after it (or tags/delimiters) + python3 -c " +with open('${UPGRADE_PLAN_DOC}', 'r') as f: + lines = f.readlines() +inside_block = False +for i, line in enumerate(lines): + if line.strip().startswith(chr(96) * 3): + if not inside_block: + if i > 0: + prec = lines[i-1].strip() + if prec != '' and not prec.startswith('{%') and not prec.startswith('---'): + print('MD031 error before line %d: %s' % (i+1, prec)) + exit(1) + inside_block = True + else: + if i < len(lines) - 1: + succ = lines[i+1].strip() + if succ != '' and not succ.startswith('{%') and not succ.startswith('---') and not succ.startswith('
