WalkthroughThe authentication upgrade exception now depends on cluster topology. DualReplica clusters and OKD SCOS clusters use separate exception handling. New table-driven tests cover excepted and non-excepted authentication degradation reasons. ChangesAuthentication upgrade monitoring
Estimated code review effort: 2 (Simple) | ~10 minutes Merge Risk: 🟡 Moderate · up to The change broadens acceptance of authentication degradations during upgrades, but it currently may also accept matching failures outside the upgrade window, and lookup cancellation errors can alter exception behavior. These localized correctness risks should be fixed or explicitly accepted before merge. Suggested reviewers: 🚥 Pre-merge checks | ✅ 14 | ❌ 1❌ Failed checks (1 warning)
✅ Passed checks (14 passed)
Full details: Stable And Deterministic Test NamesExplanation The added tests use Go's Full details: Test Structure And QualityExplanation PASS. The changed test is a standard Go table-driven unit test, not Ginkgo code. Each subtest checks the same authentication Degraded-exception behavior for one reason/topology case. It creates only in-memory intervals, uses no cluster resources, waits, Eventually, or Consistently calls, so setup/cleanup and timeout requirements do not apply. The new assertions include meaningful reason-specific messages and follow the existing package pattern of testing.T, t.Run, and testify assertions. Full details: Microshift Test CompatibilityExplanation PASS: The pull request adds a standard Go unit test, Full details: Single Node Openshift (Sno) Test CompatibilityExplanation PASS: The topic diff adds a standard Go Full details: Topology-Aware Scheduling CompatibilityExplanation PASS: The pull request changes only ClusterVersion monitor logic and its tests. The added code reads ClusterVersion data and adjusts authentication-condition exception reporting. It does not add or modify deployment manifests, pod specs, replicas, anti-affinity, topology spread, node selectors, tolerations, or PDBs. No explicit topology-aware scheduling failure condition is introduced. Full details: Ote Binary Stdout ContractExplanation PASS: The PR changes only exception logic, a Kubernetes lookup helper, and a Go unit test. The introduced lines contain no fmt print calls, os.Stdout writes, klog calls, Ginkgo suite setup, or process-level initializers. The changed package has no main, init, TestMain, BeforeSuite, AfterSuite, SynchronizedBeforeSuite, or RunSpecs function. Existing logrus calls are unchanged and are not stdout writes by this PR. Full details: Ipv6 And Disconnected Network Test CompatibilityExplanation PASS: The pull request changes only Full details: No-Weak-CryptoExplanation PASS: The full PR diff changes only the ClusterVersion operator monitor and its tests. The additions use Kubernetes client lookups and string matching for cluster conditions. They add no MD5, SHA-1, DES, 3DES, RC4, Blowfish, or ECB usage, custom cryptography, or secret/token comparisons. Full details: Container-PrivilegesExplanation PASS: The pull request changes only two Go source/test files. The added code performs ClusterVersion API lookup and adds upgrade-condition test cases. No Kubernetes/container manifest or privilege setting is introduced. The added lines contain no privileged, hostPID, hostNetwork, hostIPC, SYS_ADMIN, allowPrivilegeEscalation, or securityContext configuration. Full details: No-Sensitive-Data-In-LogsExplanation No sensitive-data logging was introduced. The changed code adds a fixed exception message and a public OCPBUGS URL, and ✨ Finishing Touches 💡 2⚔️ Resolve merge conflicts 💡

Assert the expected successful JUnit case.
At Line 769, the accepted-reason branch passes when hasFailure and hasSuccess are both false. A missing result for testName can then pass this test without validating the exception. Assert hasSuccess for every accepted reason, and assert that hasFailure is false.

also we've tightened the restrictions here which might regress two node clusters. we could just have the original check in and remove isTwoNode

... This
unblocks the OKD SCOS 5.0 promoted upgrade job which has been failing
consistently since ec.4 (OKD-424).
OKD is new to me in the e2e testing. And here is my two cents:
The current version API on Degraded does not mention which product(s) it targets. I assume it applies to OKD too.
In general, I prefer to keep the exception as narrow as possible to keep the test coverage wide.
A bug as an exception in the testing is not a fix. Instead, it is a temporary measure to give time to the owners before delivering the real fix to the bug: stop going Degraded=True and remove the exception.
If failures happen in the testing ONLY against OKD clusters, can we make the exception only for OKD and leave the existing stanza intact?
Something like
if isOKD && other-conditions {
retrurn "some exception"
}
Removing isTwoNode seems doing the opposite to my intension.
If OCP starts to have the issue on the non-two-node clusters in the future, we would not get the signal for that regression because the exception covers that up.
rather than just returning the issue link, offer a brief explanation and returning just the bug id?
That is the existing pattern for a long time (predates me working on the area).
More description/explanation could go as comments on the code, e.g.,
I feel a bit odd if we change the pattern only for one particular bug.
But I am fine with it if you think it is clearer when reading the job logs.
Could we at least get the full link back instead of bug ID for easy copy/paste?
Sadly, I had to do it so many times to load the bug page for various bugs, such as checking the status of the bug or the passing rate in Sippy for the case.

…or during upgrade The authentication operator transiently goes Degraded for ~8.5 seconds during upgrade rollout when oauth-apiserver and oauth-server pods are briefly unavailable. This is the same pattern already excepted for kube-apiserver (OCPBUGS-38661), kube-controller-manager (OCPBUGS-38662), and kube-scheduler (OCPBUGS-38663). Add a narrow exception scoped to UnavailablePod reasons only, so transient pod rollout states are classified as flakes rather than hard failures. This unblocks the OKD SCOS 5.0 promoted upgrade job which has been failing consistently since ec.4 (OKD-424).
… upgrade Verifies that the authentication operator's transient Degraded=True state during upgrade is correctly excepted for UnavailablePod reasons, while unrelated Degraded reasons remain hard failures.
- Use strings.Contains for reason matching instead of exact matches, preserving the original breadth and avoiding regressions on two-node clusters - Return a descriptive message with bug ID instead of a bare URL - Update tests to match the new strings.Contains behavior
…oNode guard Address review feedback from hongkailiu and Prashanth684: - Restore the original isTwoNode guard for DualReplica clusters - Add separate isOKD guard for OKD SCOS clusters only, keeping OCP HA uncovered so regressions are detected - Return full bug URL for easy copy-paste from job logs - Add isOKDCluster() helper following the existing isVSphere() pattern - Mark the OKD exception as temporary until the auth operator is fixed - Update tests to cover DualReplica and HA non-OKD paths separately

Pass the evaluator context to the OKD lookup. isOKDCluster performs a ClusterVersions().Get with context.Background() before the exception callback. This ignores evaluator cancellation. If rest.Config.Timeout is zero, the request has no client timeout. An error returns false and disables the OKD authentication exception. Pass ctx through and use it for the request.

Degraded=Trueexception for theauthenticationoperator during upgrade, scoped toUnavailablePodreasons onlykube-apiserver(OCPBUGS-38661),kube-controller-manager(OCPBUGS-38662), andkube-scheduler(OCPBUGS-38663)Details
During upgrade rollout, the authentication operator transiently goes
Degraded=Truefor ~8.5 seconds when oauth-apiserver and oauth-server pods are briefly unavailable. The condition reason isAPIServerDeployment_UnavailablePod::OAuthServerDeployment_UnavailablePod.The
except()function inoperators.goalready has Degraded exceptions for other control plane operators but was missing one forauthentication. Without this exception, the transient state is recorded as a hard failure rather than a flake, blocking the upgrade job.The exception is narrowly scoped to three
UnavailablePodreason combinations observed in upgrade logs — it will not mask real authentication degradations from other causes.Test plan
