Summary

  • Replace all occurrences of the openshift4 registry namespace with openshift5 across telco-hub, telco-core, and tekton build pipelines (16 files, 28 replacements).
  • Covers mirror registry configs (IDMS, ITMS, ACM), scheduling image references, Dockerfiles, kube-compare default values, ZTP site-generate image refs, and imageset-config.

Test plan

  • Verify no remaining openshift4 references in the repository (excluding submodules)
  • Validate mirror registry configurations resolve correctly with the new openshift5 path
  • Confirm tekton build pipelines reference the correct image names

Resolves: https://redhat.atlassian.net/browse/CNF-26586

📝 Walkthrough

Walkthrough

The change updates telco-core and telco-hub build labels, component images, and registry mirror configurations from OpenShift 4 references to OpenShift 5 references.

Changes

OpenShift 5 migration

Layer / File(s) Summary
OpenShift 5 image references
.tekton/*, telco-core/Dockerfile.telco-core, telco-core/configuration/*, telco-hub/Dockerfile.telco-hub, telco-hub/configuration/reference-crs/required/gitops/*, telco-hub/install/mirror-registry/*
Build labels and scheduler, ZTP site generator, and plugin image references now use OpenShift 5 repositories and versions.

telco-hub/configuration/example-overlays-config/*, telco-hub/configuration/reference-crs-kube-compare/*, telco-hub/configuration/reference-crs/required/acm/*, telco-hub/configuration/reference-crs/required/registry/*
ACM, IDMS, and ITMS configurations add or update OpenShift 5 registry sources and mirror paths.

Estimated code review effort: 2 (Simple) | ~10 minutes

Merge Risk: 🟡 Moderate · up to cd5b3

The registry namespace is changing to OpenShift 5, but related selectors, platform ranges, and operator catalogs still target OpenShift 4.22, which may cause incorrect image selection or mirror resolution. Owner confirmation or correction is needed before this is merge-ready.

…rror configs

For mirror/registry configurations (IDMS, ITMS, ACM registries.conf),
add openshift5 as a new entry while keeping the existing openshift4
entry. Direct image references remain updated to openshift5.

In other places we should limit to only openshift5 and remove the openshift4 entries. Here they may be required when ACM is managing an openshift4 cluster (tbd)

Should I add only the entry and not replace right? https://github.com/openshift-kni/telco-reference/pull/907/changes#diff-6e234dcd417e4995be309377f8b3d003281be4f2053ebfc7b234b56ee869f0a5R242

What about the rhel9 suffixes? Are those still going to be valid for all the containers?

What do you mean sorry?

Per review feedback, Hub RDS should only include mirrors for the
needed release. Remove openshift4 entries from IDMS, ITMS, and
kube-compare default_value configs, keeping only openshift5.
ACM registries.conf retains both entries as it may need openshift4
when managing older clusters (tbd).

name=openshift5/openshift-telco-core-rds**-rhel9**

Since OCP 5 will use RHCOS 10, will this change the suffix of the built containers? Or will that happen only after the containers are rebuilt on top of ubi10 sometime in the future?

Yes, this will happen only after containers are rebuilt on ubi10
