(WIP) OCPBUGS-57177

[isabella-janssen]

Note that this should not merge until after openshift/machine-config-operator#6443

This updates the PinnedImages tests for invalid PIS applications to ensure that the corresponding PinnedImageSetsDegraded MCN condition becomes True and that the node's associated MCP degrades.

Summary by CodeRabbit

• Bug Fixes
  • Improved validation of invalid pinned image configurations by confirming the targeted pool reports a degraded state.
  • Preserved existing skip behavior for applicable environments.

Pipeline controller notification
This repo is configured to use the pipeline controller. Second-stage tests will be triggered either automatically or after lgtm label is added, depending on the repository configuration. The pipeline controller will automatically detect which contexts are required and will utilize /test Prow commands to trigger the second stage.

For optional jobs, comment /test ? to see a list of all defined jobs. To trigger manually all jobs from second stage use /pipeline required command.

This repository is configured in: automatic mode

Walkthrough

The pinned-image tests retain the Hypershift skip behavior and now verify that invalid PinnedImageSets degrade the targeted MachineConfigPool after MachineConfigNode degradation.

Changes

PinnedImageSet validation

Layer / File(s)	Summary
Invalid PinnedImageSet degradation checks test/extended/machine_config/pinnedimages.go	The test documentation now states the MCP degradation requirement. The invalid-PinnedImageSet path waits for Degraded=True on the targeted MachineConfigPool after checking each MachineConfigNode. The Hypershift skip comment is updated.

Estimated code review effort: 1 (Trivial) | ~5 minutes

Merge Risk: 🟡 Moderate · up to 70183

The test now validates degraded MCP behavior, but its 30-second wait may fail prematurely on slower clusters even when the behavior is correct. The PR is not merge-ready until the timeout is increased or this bounded reliability risk is explicitly accepted.

Single Node Openshift (Sno) Test Compatibility	✅ Passed	The PR adds no Ginkgo tests or multi-node assumptions. The changed invalid-PIS check uses MCP/MCN APIs, and the custom-pool test already skips Single Node topology.

Ipv6 And Disconnected Network Test Compatibility	✅ Passed	The diff adds no Ginkgo tests, IPv4 assumptions, or external connections; it only waits for MCP Degraded=True through the existing cluster API helper. The existing quay.io image is unchanged.

Container-Privileges	✅ Passed	The PR changes only one Go test file. The diff adds condition polling and comments, with no container/Kubernetes manifest privilege settings.
No-Sensitive-Data-In-Logs	✅ Passed	The diff adds only static status messages and the MCP resource name; it adds no password, token, API key, PII, hostname, or customer-data logging.

🩺 Stability & Availability | 🟠 Major | ⚡ Quick win

Increase the MCP wait timeout.

WaitForMCPConditionStatus allows only 30 seconds for the MCP controller to set MachineConfigPoolDegraded=True after PinnedImageSetsDegraded=True. A slow cluster can fail this test before the condition propagates. The analogous check in test/extended/machine_config/machine_config_node.go waits up to 8 minutes. Use a cluster-scale timeout here as well.

Suggested adjustment

-				err = WaitForMCPConditionStatus(oc, pool.Name, mcfgv1.MachineConfigPoolDegraded, corev1.ConditionTrue, 30*time.Second, 5*time.Second)
+				err = WaitForMCPConditionStatus(oc, pool.Name, mcfgv1.MachineConfigPoolDegraded, corev1.ConditionTrue, 8*time.Minute, 3*time.Second)
