What does this PR do?

Updates ART tools to support MicroShift bootc shipments containing both RHEL 9 and RHEL 10 builds.

Why is this needed?

MicroShift bootc produces separate RHEL 9 and RHEL 10 images. Each version requires its own snapshot and RHEL-specific ReleasePlans.

Additionally, RPA validation was deriving legacy unsuffixed names such as:

  • ocp-art-advisory-stage-5-0
  • ocp-art-advisory-prod-5-0

Those RPAs were replaced by RHEL-specific RPAs.

Changes

  • Add shared helpers for:
    • Grouping NVRs by RHEL version.
    • Resolving RHEL-specific ReleasePlans.
  • Update build-microshift-bootc to:
    • Create separate snapshots for RHEL 9 and RHEL 10.
    • Generate separate shipment files in one shipment MR.
    • Reuse the branch of an existing open shipment MR.
    • Remove the legacy combined shipment file.
  • Update shipment MR parsing to preserve RHEL-qualified shipment kinds.
  • Update RPA validation to use the ReleasePlans declared in the shipment configuration.
  • Preserve legacy derived RPA-name behavior for callers without configured ReleasePlans.
  • Add regression coverage for multi-RHEL shipment generation and RPA validation.

Summary by CodeRabbit

  • New Features

    • Process shipment configurations separately for each RHEL version.
    • Generate version-specific shipment files, snapshots, ReleasePlans, and release names, allowing multiple versions to coexist without collisions.
    • Group builds by RHEL version and reuse existing shipment merge request branches.
    • Support RHEL-specific release-plan mappings with fallback to shared configuration values.
    • Validate releases using configured stage and production ReleasePlans.
  • Bug Fixes

    • Preserve distinct RHEL-qualified shipment configuration names.
    • Remove legacy combined shipment files when version-specific configurations are generated.

In response to this:

What does this PR do?

Updates the build-microshift-bootc pipeline to generate separate shipment configurations for each RHEL version supported by MicroShift bootc.

Why is this needed?

MicroShift bootc produces both RHEL 9 and RHEL 10 builds. These builds require separate snapshots and ReleasePlans, while still being managed in a single shipment MR.

Changes

  • Reuse the shared RHEL-version grouping and ReleasePlan lookup logic from binary_release_konflux.
  • Generate separate el9 and el10 snapshots.
  • Generate separate shipment files:
    • microshift-bootc-el9
    • microshift-bootc-el10
  • Reuse the branch from an existing open shipment MR when configured.
  • Remove the legacy combined shipment file when migrating an existing MR.
  • Preserve RHEL-qualified shipment kinds when parsing shipment MRs.
  • Add unit tests covering grouping, ReleasePlan resolution, branch reuse, and multi-file shipment updates.

Walkthrough

The change preserves RHEL-qualified shipment kinds and adds shared helpers for RHEL grouping and ReleasePlan lookup. MicroShift shipment preparation now creates separate snapshots, configurations, and shipment files for each RHEL version.

Changes

RHEL-specific shipment support

Shipment kind and shared helper contracts

Shipment detection preserves -elN variants. Shared helpers group NVRs and resolve RHEL-specific or base ReleasePlans.

Shipment updates write all RHEL-specific files together. Binary release processing uses shared grouping and ReleasePlan helpers.
ReleasePlan-aware validation
elliott/elliottlib/cli/konflux_release_cli.py, pyartcd/pyartcd/pipelines/prepare_release_konflux.py, elliott/tests/test_konflux_release_cli.py
RPA validation uses configured stage and production ReleasePlans when available. RHEL-qualified shipment filenames produce qualified release object names.

Priority: ➖ Normal

Estimated code review effort: 4 (Complex) | ~45 minutes

Merge Risk: ⚪ Minimal · up to 131cc

MicroShift RHEL 9 and RHEL 10 shipments now use distinct release object names and configured ReleasePlans, avoiding multi-RHEL naming collisions. The change is ready to merge.

Assert the snapshot contents per RHEL group.

The test verifies the number of snapshot calls but not which NVRs went into each snapshot. A grouping error that put the el10 NVR into the el9 snapshot would still pass. Assert the arguments of each _create_snapshot call.

♻️ Proposed additional assertion

Add microshift-bootc-rhel9 and microshift-bootc-rhel10 to OCP_RPA_KINDS.

The guard rejects these kinds before it reads configured release_plans. Add tests for both qualified kinds.
