OCPBUGS-109671: monitortests: allow image-registry node-ca Progressing on DualReplica

[eggfoobar]

During TNF upgrades, MCO node reboots recreate the node-ca DaemonSet and CIMO briefly reports NodeCADaemonProgressing while the registry stays Available. Except that Progressing-while-MCO blip on two-node topologies.

monitortests: require NodeUpdate overlap for image-registry node-ca exception

Limit the DualReplica Progressing-while-MCO allowlist for NodeCADaemonProgressing to blips that overlap a node-lifecycle Update window (+1m grace), so unrelated registry Progressing is not excepted for the whole MCO Progressing period.

Summary by CodeRabbit

• Bug Fixes

  • Improved upgrade monitoring to correctly handle temporary node certificate authority progressing states during overlapping node updates.
  • Added a one-minute grace period after node updates to reduce false-positive upgrade alerts.

• Tests

  • Added coverage for recognized progressing reasons, overlapping update windows, grace-period boundaries, and events occurring outside update intervals.
  • Expanded validation of upgrade monitoring behavior during node update transitions.

Walkthrough

The monitor recognizes NodeCADaemonProgressing reasons and matches them against node update intervals with a one-minute grace period. Upgrade exception handling receives event intervals and permits matching two-node image-registry transitions during eligible intervals.

Changes

NodeCA progressing exception

Layer / File(s)	Summary
Interval matching and validation pkg/monitortests/clusterversionoperator/legacycvomonitortests/operators.go, pkg/monitortests/clusterversionoperator/legacycvomonitortests/operators_test.go	Helpers recognize valid NodeCADaemonProgressing reasons, collect phase-Update node intervals, and test overlap with the one-minute grace period. Tests cover boundaries and non-overlapping intervals.
Progressing exception integration pkg/monitortests/clusterversionoperator/legacycvomonitortests/operators.go	The exception callback receives the event interval. Image-registry progressing events are excepted only when they match a two-node update interval and its grace period.

Estimated code review effort: 2 (Simple) | ~10 minutes

Merge Risk: ⚪ Minimal · up to 0819c

This localized change narrows the image-registry node-ca exception to node-update overlap during MCO activity; no actionable merge-blocking risk remains beyond normal checks and review.

Check name	Status	Explanation
Description Check	✅ Passed	Check skipped - CodeRabbit’s high-level summary is enabled.
Title check	✅ Passed	The title clearly describes the main change: allowing image-registry NodeCADaemonProgressing during DualReplica node updates.
Docstring Coverage	✅ Passed	No functions found in the changed files to evaluate docstring coverage. Skipping docstring coverage check.
Linked Issues check	✅ Passed	Check skipped because no linked issues were found for this pull request.
Out of Scope Changes check	✅ Passed	Check skipped because no linked issues were found for this pull request.
Stable And Deterministic Test Names	✅ Passed	The PR adds static test names and table-driven subtest labels such as “bare reason” and “during node update”; no Ginkgo titles or dynamic run-dependent values were introduced.
Test Structure And Quality	✅ Passed	The added tests use standard Go testing with table-driven subtests, not Ginkgo It blocks; the Ginkgo-specific check is therefore inapplicable.
Microshift Test Compatibility	✅ Passed	The diff adds only standard Go unit tests using testing.T and assert; it adds no Ginkgo e2e tests or MicroShift-incompatible test execution.
Single Node Openshift (Sno) Test Compatibility	✅ Passed	The diff adds only ordinary Go testing.T unit tests and no new Ginkgo e2e tests, so the SNO compatibility check does not apply.
Topology-Aware Scheduling Compatibility	✅ Passed	The diff changes only cluster-version monitor logic and unit tests; it adds no pod specs, manifests, affinity, spread constraints, selectors, tolerations, replica settings, or PDBs.
Ote Binary Stdout Contract	✅ Passed	The diff adds interval filtering, reason matching, and unit tests only; structural searches found no fmt.Print*, log.Print, klog, or suite-level stdout writes.
Ipv6 And Disconnected Network Test Compatibility	✅ Passed	The PR adds ordinary Go unit tests and interval helpers only; no Ginkgo e2e tests, IPv4 literals, IP parsing, network URLs, or external connectivity were introduced.
No-Weak-Crypto	✅ Passed	The diff only adds node-update interval logic and tests. Changed files import no crypto packages and add no MD5, SHA1, DES, RC4, 3DES, Blowfish, ECB, custom crypto, or secret comparisons.
Container-Privileges	✅ Passed	The diff changes only two Go monitor-test files; no manifest-like files or privileged, host*, SYS_ADMIN, root, or allowPrivilegeEscalation settings appear in added lines.
No-Sensitive-Data-In-Logs	✅ Passed	The diff adds only fixed diagnostic text, reason matching, and interval filtering; it introduces no passwords, tokens, API keys, PII, customer data, or new logging sink.
