OCPEDGE-2958: Add topologyTransitionStatus field to Infrastructure status by copejon · Pull Request #3026 · openshift/api

copejon · 2026-09-09T03:59:54Z

Summary

Adds a new status.topologyTransitionStatus field to the Infrastructure API to track the current state of control-plane topology transitions (e.g. SingleReplica <-> HighlyAvailable), for use by the TopologyTransitionController in cluster-config-operator.

Adds TopologyTransitionStatus type with Available, Pending, Error, and Transitioned values.
Adds InfrastructureStatus.TopologyTransitionStatus, defaulting to HighlyAvailable.
Regenerates CRD manifests, deepcopy, and OpenAPI.

Pipeline controller notification
This repo is configured to use the pipeline controller. Second-stage tests will be triggered either automatically or after lgtm label is added, depending on the repository configuration. The pipeline controller will automatically detect which contexts are required and will utilize /test Prow commands to trigger the second stage.

For optional jobs, comment /test ? to see a list of all defined jobs. To trigger manually all jobs from second stage use /pipeline required command.

This repository is configured in: LGTM mode

📝 Walkthrough

Walkthrough

The API adds an optional topology transition status field to InfrastructureStatus. The status includes a human-readable message and one of five typed status values. The Infrastructure and ControllerConfig CRD schemas expose the corresponding status object and enum.

Suggested reviewers: vr4manta, mkowalski

Merge Risk: ⚪ Minimal · up to 5b60d

The new status field is consistently exposed in the inspected API schemas. No issue identified here prevents merging after normal checks.

Document the RetryWithBackoff state in the field comment.

The enum for controlPlaneTopologyTransitionStatus allows RetryWithBackoff. The field doc comment does not explain it. kubectl explain infrastructure.status.controlPlaneTopologyTransitionStatus shows only this field-level comment. It does not show the separate TopologyTransitionStatus type comment, which does document RetryWithBackoff. Add a bullet for RetryWithBackoff here, consistent with the other four states.

 	// "Error" means a requested transition could not be admitted, either
 	// because the requested topology change is not a supported transition or
 	// because a precondition was not met. The specific reason is reported as
 	// an Event on this Infrastructure object rather than in this field.
 	//
+	// "RetryWithBackoff" means the controller encountered a synchronization or
+	// API error while reconciling the transition and is retrying with
+	// backoff. This is distinct from "Error", which means the transition
+	// was not admitted at all.
+	//
 	// "Transitioned" means the most recently requested transition completed
 	// successfully; spec.controlPlaneTopology matches status.controlPlaneTopology.

Chat

There are 3 ways to chat with CodeRabbit:

Review comments: Directly reply to a review comment made by CodeRabbit. Example:
- I pushed a fix in commit <commit_id>, please review it.
- Open a follow-up GitHub issue for this discussion.
Files and specific lines of code (under the "Files changed" tab): Tag @coderabbitai in a new review comment at the desired location with your query.
PR comments: Tag @coderabbitai in a new PR comment to ask questions about the PR branch. For the best results, please provide a very specific query, as very limited context is provided in this mode. Examples:
- @coderabbitai gather interesting stats about this repository and render them as a table. Additionally, render a pie chart showing the language distribution in the codebase.
- @coderabbitai read the files in the src/scheduler package and generate a class diagram using mermaid and a README in the markdown format.
