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 separate control-plane and infrastructure topology transition status fields to InfrastructureStatus. It defines five typed transition states, including retry and completed states. The fields are gated by MutableTopology, default to NotTransitioned, and omit empty JSON values. Infrastructure and ControllerConfig CRD schemas now expose both fields with matching defaults, enums, and descriptions.

Suggested reviewers: vr4manta, mkowalski, sadasu

Priority: ➖ Normal

Merge Risk: 🔵 Low · up to ca12e

The new API remains functional, but its published status documentation is incomplete and contains visible errors. Correct the source comments and regenerate manifests for accurate operator guidance.

+	ControlPlaneTopologyTransitionStatus TopologyTransitionStatus `json:"controlPlaneTopologyTransitionStatus,omitempty"`

+	// InfrastrutureTopologyTransitionStatus reports the current state of a

Might we need to review this field considering the upcoming spec.infrastructureTopology field from Standalone Infrastructure Topology Transition?

More details on the dedicated deliverables' doc.

The linked doc describes status reporting via CCO condition messages, which is a pattern that this work deprecates and replaces with first class citizen fields under .status. So the work here is orthogonal to the work described in the doc.

…dle" describes an operating status, not a transition state and could lead to confusion

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

 	// "Transitioned" means the most recently requested transition completed

Fix typos in the infrastructureTopologyTransitionStatus field comment.

Line 167 misspells InfrastructureTopologyTransitionStatus as InfrastrutureTopologyTransitionStatus. Line 170 misspells definitions as definitinos. Line 168 needs the article "an" before "infrastructure topology transition".
