WalkthroughThe cleanup controller now removes the internal registry pull-secret annotation from a service account when the annotation references the image pull secret being deleted. ChangesInternal registry secret cleanup
Estimated code review effort: 1 (Trivial) | ~3 minutes Merge Risk: 🟡 Moderate · up to The cleanup change can leave ServiceAccounts in an incorrect cached state when an update fails, causing later reconciliation to skip removing the registry reference. This is a concrete correctness risk that should be addressed before merge. 🚥 Pre-merge checks | ✅ 15✅ Passed checks (15 passed)

Deep-copy the ServiceAccount before mutation.
serviceAccountLister.List returns read-only informer-cache objects. If Update fails, these mutations can leave the cache without the reference while the API object still contains it. A later reconcile can skip cleanup. Deep-copy before modifying Secrets, ImagePullSecrets, or Annotations, and add a conflict-path test.

I've drafted some changes to add DeepCopy() into the code for service accounts, but waiting for the reviewers to confirm if this is necessary or not.

@vwalek, DeepCopy() is necessary.
serviceAccountLister.List returns objects from the shared informer cache. The cleanup flow mutates Secrets, ImagePullSecrets, and now Annotations before ServiceAccounts(...).Update.
If Update fails, the informer cache can retain those mutations even though the API object was not updated. A later reconcile can then use incorrect cached state.
Create the copy before the first mutation and use it for the rest of that iteration:
serviceAccount = serviceAccount.DeepCopy()Please also add the conflict-path test. The test should verify that a failed update does not modify the cached ServiceAccount.

Summary
Fixes a reconcile loop in
ImagePullSecretCleanupControllerwhen the internal image registry is removed.The controller already removed dockercfg secret references from ServiceAccounts, but left the
openshift.io/internal-registry-pull-secret-refannotation behind. BecauseimagePullSecretForServiceAccount()reads that annotation, the controller kept reconciling the same ServiceAccounts and issuing repeated updates to the API server.This PR removes the annotation when it references the secret being cleaned up.
Fixes OCPBUGS-91973.
