WalkthroughThis change adds a provisional design for replacing the deprecated OpenShift image registry with an in-cluster Quay/distribution-based registry. It defines workflows, authorization, storage, operator integration, lifecycle behavior, testing, and graduation criteria. ChangesQuay-powered registry replacement
Estimated code review effort: 1 (Trivial) | ~5 minutes Mergeability Score: 🟡 Moderate · up to This PR proposes replacing the image registry with a Quay-backed implementation, but it does not yet define compatibility and authorization behavior for mixed rollouts, rollback, quota rejection, listing, feature-gate states, and OCI referrers. These gaps could make image data unavailable, inconsistent, or incorrectly exposed during migration, so merge should wait for explicit contracts and targeted validation. 🚥 Pre-merge checks | ✅ 15✅ Passed checks (15 passed)

- Around line 14-15: Resolve the invalid Jira tracking reference associated with
PROJQUAY-12512 by updating the Jira issue to target version 5.0.0 or changing
the PR title/reference to a valid issue, and refresh the Jira metadata
afterward.
- Around line 130-135: Update the image-pruning workflow to state that the Quay
implementation preserves the existing ImagePruner contract, including the
dedicated service account, system:image-pruner RBAC, CronJob reconciliation, and
ManagementState-dependent --prune-registry behavior described by the established
pruning design.
- Around line 107-108: Update the quota-exceeded requirement in the image
registry replacement workflow to define how LimitRange accounts for blob bytes
and ResourceQuota accounts for ImageStream tag counts, including when quota is
reserved or checked. Specify behavior for concurrent pushes and cleanup of
uploaded blobs, manifests, and Image metadata when a push is rejected.
- Around line 11-12: Replace the placeholder values for creation-date and
last-updated in the proposal metadata with the actual dates in yyyy-mm-dd
format, ensuring both fields reflect the document’s history before finalizing
the proposal.
- Around line 125-126: Update the catalog listing behavior so results are
filtered by the caller’s namespace and repository permissions before any
ImageStream entries are returned; alternatively disable catalog listing if
authorization filtering cannot be enforced. Add a negative test proving
unauthorized cross-namespace ImageStreams are not exposed.
- Around line 139-145: Define a precedence matrix covering
QuayIntegratedRegistry, ManagementState values Managed, Removed, and Unmanaged,
and storage readiness, including bootstrap without shareable object storage.
Specify when the operator may transition from Removed to Managed after storage
configuration and how the feature gate behaves during enabled and rollback
states, while preserving the existing storage contract.
- Around line 37-41: Correct the specified spelling, grammar, capitalization,
and spacing errors throughout the document, including “decision,”
“namespace-scoped,” “Feature,” “API,” “unreferenced,” “OKE-specific,”
“introduce,” “Adherence,” “Disabling,” “a registry,” and the duplicated space in
“many existing.”
- Around line 83-84: Add explicit storage compatibility tests to the proposal
before claiming migration-free instant rollback: cover filesystem, S3, Azure,
GCS, Swift, partial uploads, OCI 1.1 referrers, and concurrent legacy/new pods.
Extend the existing upgrade/downgrade test plan to verify each scenario works
across rollback without migration.

Define feature-gate behavior for ManagementState and missing storage.
The existing storage contract allows platforms without shareable object storage to bootstrap in Removed and become Managed only after storage is configured, as described in enhancements/image-registry/remove-registry-baremetal.md, Lines [35]-[70]. Add a precedence matrix for the feature gate, Managed/Removed/Unmanaged, and storage readiness.

In `@enhancements/image-registry/quay-powered-image-registry-replacement.md`:
- Around line 124-125: Update the tag-listing workflow to perform a
resource-scoped authorization check on the target ImageStream before reading or
returning ImageStream.status.tags. Deny requests for unauthorized resources,
including cross-namespace ImageStreams, and add a test covering the denied
cross-namespace case.
- Around line 200-204: Define OCI 1.1 referrer ownership in the Image and
ImageStream workflow: link signature and other referrer manifests to their
subject, support referrer queries, and retain both subjects and referrers when
tags are deleted or unreferenced-image pruning runs. Add lifecycle and
integration tests covering push, lookup, deletion, and pruning behavior.
- Around line 208-211: Update the TokenReview and SubjectAccessReview
authorization flow to use request deadlines or cancellation, bounded retries,
and appropriate caching or rate limiting so slow or failing Kubernetes API calls
cannot block or overload registry requests. Define the failure behavior for
authorization API errors and add load-oriented tests covering timeouts,
cancellations, retry bounds, and sustained API failures while preserving
existing image-puller and image-builder role authorization.
- Around line 104-107: Define recovery for failures between the OCI
blob/manifest writes and the Kubernetes commit: use digest-based idempotency for
retries, reconcile storage content with the Image CR and ImageStream state, and
clean up orphaned content when the commit cannot complete. Specify behavior for
each failure point, including concurrent retries and eventual consistency.
- Around line 190-194: Define the registry ServiceAccount security boundary in
the design: specify separate operator and registry identities, least-privilege
RBAC for the registry’s TokenReview and SubjectAccessReview calls, the mounted
token audience, and explicit automount behavior.
- Around line 119-120: Define the remote source-selection policy before enabling
pull-through behavior, requiring an administrator-controlled registry allowlist
and rejecting unapproved sources. Specify enforcement for redirect and DNS
revalidation, egress restrictions, scoped credentials, and bounded fetch limits
to prevent access to internal services or cloud metadata.
