WalkthroughThe authentication upgrade exception now matches any ChangesAuthentication upgrade monitoring
Estimated code review effort: 2 (Simple) | ~10 minutes Merge Risk: 🟡 Moderate · up to The change may suppress genuine authentication degradation outside an upgrade window when specific pod-unavailable reasons occur, potentially allowing an unhealthy cluster state to pass monitoring. The exception should be restricted to upgrades and covered by an out-of-window regression test before merge. Suggested reviewers: 🚥 Pre-merge checks | ✅ 14 | ❌ 1❌ Failed checks (1 warning)

- Around line 332-337: Restrict the OCPBUGS-111997 exception branch in the
relevant operator condition handling to cases where withinUpgradeWindowBuffer is
true, so matching authentication degradation outside the upgrade window is not
accepted. Add a regression test covering an out-of-window matching event and
preserve the existing upgrade-window behavior.
- Around line 332-337: Update the OCPBUGS-111997 condition handling in the
relevant operator-reason mapping to recognize producer-supported composite
authentication reasons by matching the supported
APIServerDeployment_UnavailablePod and OAuthServerDeployment_UnavailablePod
components, including composites with additional reasons and either supported
ordering, instead of relying only on exact reason equality. Add table-driven
tests covering composite, extended, and producer-supported ordering cases.

…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.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win
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.
Proposed fix

- if hasFailure {
- assert.True(t, hasSuccess, "expected both failure and success JUnit (flake) for reason %s", tt.reason)

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

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
