Merge Risk: 🔵 Low · up to The credential-rotation logic looks sound. Two small issues in the end-to-end tests could make them flaky or slow. A pull-test pod can run on a node whose credentials were not yet checked. A registry probe has no time limit, so it can hang during rollout. Both are quick test fixes and do not affect production behavior. Important Pre-merge checks failedPlease resolve all errors before merging. Addressing warnings is optional. ❌ Failed checks (1 error, 2 warnings)
✅ Passed checks (12 passed)
Full details: Test Structure And QualityExplanation The new rotation test adds timeout gaps and several context-free assertions. Resolution Use context-aware, bounded node command execution, or apply appropriate command-level timeouts to every polled node operation, including the registry curl and kubelet config check. Add meaningful messages to all new assertions, including secret retrieval/update, htpasswd generation, reconciliation, API reads, and empty-password validation. Make pull-test pod cleanup use a bounded context and report cleanup failures clearly.

Use a bounded context for Secrets.Update.
reconcileHtpasswd calls Secrets.Update with context.TODO(). The worker does not propagate its Run context, and the production client leaves rest.Config.Timeout at its zero value, which client-go defines as no timeout. A stalled API request can therefore keep the reconciliation worker blocked without a deadline.
Pass a bounded context into reconcileHtpasswd and use it for Secrets.Update.

Bound each node-executed curl request.
wait.PollUntilContextTimeout cannot stop this callback while ExecCmdOnNode waits in cmd.Output(). The helper creates the command without a context and retries only after it returns. This curl command has no connection or overall timeout, so a stalled registry request can block the poll beyond its two-minute deadline. Add finite --connect-timeout and --max-time values to the registry requests, or use a context-aware execution helper.

Let the outer timeout bound the image-pull wait.
The inner two-minute wait.PollUntilContextTimeout returns context deadline exceeded when the pull remains in progress. The callback returns that error instead of retrying the pod, so the outer ten-minute retry stops after two minutes. Pod recreation is reserved for ImagePullBackOff and ErrImagePull; the shorter deadline is not required for an in-progress pull.
Use the supplied outer context for the inner poll.

- return wait.PollUntilContextTimeout(ctx, 3*time.Second, 2*time.Minute, true, func(ctx context.Context) (bool, error) {

Implement credential rotation that accepts brief registry downtime. When an admin updates iriAuthSecret.Data["password"], the controller: 1. Detects the mismatch between password and htpasswd (via bcrypt compare) 2. Generates a new bcrypt hash and updates iriAuthSecret.Data["htpasswd"] 3. Re-renders the master MachineConfig with the new htpasswd 4. MCD rolls out the updated MC; brief downtime for IRI registry during rollout is accepted Key changes: - Add kubeClient field to IRI controller (needed to update auth secret) - Add reconcileHtpasswd to detect password/htpasswd mismatch and regenerate the bcrypt hash; moved to internalreleaseimage_registry_auth.go alongside the bcrypt helpers (generateHtpasswdEntry, HtpasswdMatchesPassword) - Add NoneStatusAction for /etc/iri-registry/auth/htpasswd in NodeDisruptionPolicy (distribution registry re-reads htpasswd on mtime change, no restart needed) - Add unit tests for reconcileHtpasswd - Add e2e test for the full rotation flow (TestIRIAuth_CredentialRotation); uses ExecCmdOnNode via MCD pod to reach api-int:22625 in CI Assisted-by: Claude Sonnet 4.6 <noreply@anthropic.com>
Move readIRIAuthToken from a standalone function into a method on iriRegistry (readAuthToken), and have newIRIRegistry call it internally rather than requiring the caller to resolve credentials beforehand. newIRIRegistry now returns (*iriRegistry, error) and accepts an optional authTokenOverride used in tests; in production the override is always empty and the token is read from the kubelet auth file at construction time. The manager sync path shrinks from 7 lines to 3. Assisted-by: Claude Sonnet 4.6 <noreply@anthropic.com>

Add verifyCanPullFromIRI helper that creates a pod with imagePullPolicy:Always using the IRI release image (pulled from the local IRI registry, not quay.io) and verifies the kubelet can authenticate and pull it. This exercises the full kubelet credential lookup path (/var/lib/kubelet/config.json) rather than just raw HTTP auth via curl exec. Add getIRIReleasePullSpec helper that queries /v2/openshift/release-images/tags/list on the IRI registry and constructs the local pullspec (api-int.<baseDomain>:22625/openshift/release-images:<version-tag>). Add pre-rotation and post-rotation pull checks to TestIRIAuth_CredentialRotation. The existing curlIRIRegistry checks are retained for old-credential rejection verification. Assisted-by: Claude Sonnet 4.6 <noreply@anthropic.com>
…edentials rejected
The old-credential 401 check after rotation was running immediately after
observing a single api-int 200 from curlIRIRegistry. Since api-int is a VIP
that load-balances across masters, this only proved one backend had the new
htpasswd; the 401 probe could land on an unrotated master and return 200.
Wait for WaitForPoolCompleteAny("master") before the old-credential assertion
to ensure all masters have applied the new htpasswd before we check rejection.
Assisted-by: Claude Sonnet 4.6 <noreply@anthropic.com>
Three fixes for reliability of the post-rotation verifyCanPullFromIRI check: 1. Retry getIRIReleasePullSpec until tags are available. After credential restores the IRI registry can take a moment to stabilize; querying tags immediately can return an empty list causing a spurious test failure. 2. Wait for /var/lib/kubelet/config.json to contain the new IRI credentials before creating the pull-test pod. Credential rotation triggers two sequential MC rollouts (02-master for htpasswd, 00-master for pull secret); WaitForPoolCompleteAny returns after the first, so without this wait the pod is created before the pull secret is updated. 3. Retry the pull-test pod if it hits ImagePullBackOff. CRI-O can cache authentication failures briefly; deleting and recreating the pod forces a fresh authentication attempt with the updated credentials.

After FeatureGateNoRegistryClusterInstall has been promoted to default, fix the outdated comment.

Add the curl timeouts to curlIRIRegistry.
Lines 41-42 define curlConnectTimeout and curlMaxTime, but only getIRIReleasePullSpec uses them. curlIRIRegistry still runs curl without a connect limit or a total time limit. waitForIRICredentialsAccepted calls curlIRIRegistry inside wait.PollUntilContextTimeout, and the old-credential probe at Line 651 also calls it. ExecCmdOnNode does not observe the poll context, so a stalled registry during a rollout can block past the poll deadline.
Proposed fix
- args := []string{"curl", "-s", "--cacert", iriRootCAPath, "-o", "/dev/null", "-w", "%{http_code}"}
+ args := []string{"curl", "-s",
+ "--connect-timeout", curlConnectTimeout, "--max-time", curlMaxTime,
+ "--cacert", iriRootCAPath, "-o", "/dev/null", "-w", "%{http_code}"}As per path instructions: "context.Context for cancellation and timeouts".

Pin the pull-test pod to the node whose kubelet auth you verified.
waitForKubeletIRIAuth checks /var/lib/kubelet/config.json only on node. The pod from newPod has no NodeName, so the scheduler can place it on another master or on a worker. That node's 00-* pull-secret rollout can still be pending. If the pod runs there, it hits ErrImagePull with the old credentials. The loop then recreates pods until the pull succeeds or the 10-minute timeout expires. The post-rotation check at Line 669 then depends on scheduling and rollout timing instead of the verified node state.
Pass the node to the helper and set Spec.NodeName. A pod with NodeName set skips the scheduler, so NoSchedule taints on masters do not block it.

The This is due to #6109, which has the note: So I think we need to merge AGENT-1393, then revert the changes that were in #6109 |
- What I did
This replicates the implementation in #5810. This newer version of the implementation does not perform featuregate checks since this feature has been promoted to default.
Implement credential rotation that accepts brief registry downtime.
When an admin updates iriAuthSecret.Data["password"], the controller:
Detects the mismatch between password and htpasswd (via bcrypt compare)
Generates a new bcrypt hash and updates iriAuthSecret.Data["htpasswd"]
Re-renders the master MachineConfig with the new htpasswd
Updates the global pull secret with the new credentials
MCD rolls out the updated MC; brief downtime for IRI registry during
rollout is accepted
Key changes:
Add NoneStatusAction for /etc/iri-registry/auth/htpasswd in NodeDisruptionPolicy
(Distribution registry re-reads htpasswd on mtime change, no restart needed)
Add unit tests for helpers and reconcileAuthSecret
Add e2e tests: unauthenticated 401, authenticated 200, and full rotation flow
(tests use ExecCmdOnNode via MCD pod to reach api-int:22625 in CI)
- How to verify it
Update the password to trigger the rotation to start:
oc -n openshift-machine-config-operator patch secret internal-release-image-registry-auth
--type merge -p '{"data":{"password":"'$(echo -n "new-password" | base64)'"}}'
Verify the /etc/iri-registry/auth/htpasswd has been updated.
Verify iri-registry works new credentials after rollout is complete.
Verify global pull-secret contains the new credentials after rollout is complete.
- Description for the changelog
Support credential rotation in IRI registry.
