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.

📝 Walkthrough

Walkthrough

Adds TopologyTransitionStatus to InfrastructureStatus as an optional field with a default of HighlyAvailable and enum validation for HighlyAvailable and SingleReplica. Defines four status constants. Updates Infrastructure and ControllerConfig CRD schemas with the corresponding topologyTransitionStatus property.

Suggested reviewers: vr4manta, mkowalski, sadasu

Priority: ⬇️ Low

Merge Risk: 🟡 Moderate · up to 5951b

The topology transition controller cannot reliably publish its declared states through the new API, so the value contract should be corrected before merge.

Use one value contract for TopologyTransitionStatus.

The Go field and generated CRD define topology-mode values, while the new type constants define transition states. This rejects controller updates for the declared transition states. Resolve the intended default and enum once, then regenerate the schemas.

  • config/v1/types_infrastructure.go#L141-L144: make the field markers match the selected TopologyTransitionStatus values.
  • payload-manifests/crds/0000_10_config-operator_01_infrastructures-Default.crd.yaml#L2550-L2557: regenerate this CRD with the same default and enum.

This consolidation uses the Go field definition, constants, and generated CRD schema.

🌐 Web query:

site:github.com/openshift/api "topologyTransitionStatus" "HighlyAvailable"

💡 Result:

In the context of Red Hat OpenShift, "HighlyAvailable" is a defined value for the ControlPlaneTopology field within the Infrastructure configuration API [1]. It represents the standard behavior for operators in a typical cluster deployment, where control plane components are configured to ensure high availability [1]. The ControlPlaneTopology field accepts several modes, including: - HighlyAvailable: The default mode for a normal cluster deployment [1]. - HighlyAvailableArbiter: A configuration consisting of two regular-sized control plane nodes and one smaller arbiter node, designed to maintain quorum in edge deployments [1][2]. - SingleReplica: Used for single-node deployments where high-availability configuration is not applied [1]. - External: Indicates that the control plane is hosted externally and is not visible within the cluster [1]. - DualReplica: Indicates that the control plane consists of two nodes with fencing-enabled operation [3]. These modes allow OpenShift operators to adapt their configuration based on the deployment's requirements and topology [1][2]. As of September 2026, these structures are part of the OpenShift configuration API (config/v1) [1][4].

Correct the TopologyTransitionStatus marker and regenerate the CRDs.

config/v1/types_infrastructure.go defines Available, Pending, Error, and Transitioned, but the field marker generates only HighlyAvailable and SingleReplica. The HighlyAvailable default is also invalid for this type. Use the four defined status values, set the default to Available, and regenerate all affected Infrastructure and ControllerConfig manifests.
