- What I did

Fixed the devex helpers onclustertesting and mco-push as follows:

onclustertesting:

  • Dropped requirement for FeatureGate because OCL is now considered GA.
  • Fixed oc registry login command to include the internal registry hostname in the pull secret.

mco-push:

  • Added retry-on-conflict resolution for scaling operations.

- How to verify it

The devex helpers should work as expected. The internal registry fix for onclustertesting is used in the e2e-ocl-1of2 and e2e-ocl-2of2 test jobs, so they are able to validate this change.

- Description for the changelog
Fixes MCO devex helpers

Summary by CodeRabbit

  • Bug Fixes

    • Improved reliability when updating deployment replica counts and machine configuration pool pause states during concurrent changes.
    • Updated registry login handling to target the internal image registry explicitly.
    • Rollout, build, replacement, restart, and rollback operations now stop promptly when canceled or timed out.
  • Changes

    • Removed feature-gate validation and the feature-gate enabling option from on-cluster testing setup workflows.

Walkthrough

The change removes feature-gate handling from on-cluster testing, propagates command contexts through cluster operations, adds context-aware conflict retries, and targets registry login at the internal registry service.

Changes

On-cluster testing setup

Layer / File(s) Summary
Remove feature-gate setup flow
devex/cmd/onclustertesting/featuregate.go, devex/cmd/onclustertesting/opts.go, devex/cmd/onclustertesting/setup.go, devex/cmd/onclustertesting/ci.go
The feature-gate command, option, flag, validation calls, and CI setup gate check were removed.

Context-aware cluster operations

Layer / File(s) Summary
Propagate command contexts
devex/cmd/mco-builder/*, devex/cmd/mco-push/*
Cobra command contexts now flow through builder, push, revert, validation, registry, secret, image-stream, and rollout operations.
Make rollout retries context-aware
devex/internal/pkg/rollout/rollout.go
Rollout API calls use caller-provided contexts. ConfigMap, Deployment, DaemonSet, and replica-scale conflict retries stop after context cancellation or expiration.
Retry MachineConfigPool updates
devex/internal/pkg/utils/apiutils.go
MachineConfigPool pause-state updates refetch the resource and retry after update conflicts.

Internal registry authentication

Layer / File(s) Summary
Set registry login target
test/helpers/longlivedsecrets.go
oc registry login now receives image-registry.openshift-image-registry.svc:5000 through --registry.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: 🟠 High · up to 218af

An interrupted rollout can leave the Cluster Version Operator or Machine Config Operator scaled to zero, preventing expected cluster update and rollout activity until recovery. This high-impact merge-readiness risk should be fixed before merging; an unused helper may also fail lint checks.


Important

Pre-merge checks failed

Please resolve all errors before merging. Addressing warnings is optional.

❌ Failed checks (1 error, 1 warning)

Check name Status Explanation Resolution
No-Sensitive-Data-In-Logs ❌ Error The PR adds an internal registry hostname to oc registry login; on command failure, existing cmd.String() error formatting propagates it to require.NoError test output. Keep the registry argument, but redact or omit internal hostnames from command strings and propagated error messages before they reach test or application logs.
Docstring Coverage ⚠️ Warning Docstring coverage is 3.03% which is insufficient. The required threshold is 80.00%. Docstring coverage is scoped to functions touched by this diff. Analyzed 33 functions across 11 files. Write docstrings for the functions missing them to satisfy the coverage threshold.
✅ Passed checks (13 passed)
Check name Status Explanation
Description Check ✅ Passed Check skipped - CodeRabbit’s high-level summary is enabled.
Title check ✅ Passed The title accurately identifies DevEx helper changes, although it does not specify the context, feature-gate, registry, and retry updates.
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 changes no Ginkgo test titles or test files; AST and diff checks found no It, Describe, Context, or When calls in changed files.
Test Structure And Quality ✅ Passed The PR changes no Ginkgo It blocks or test setup; its only test-path change updates an oc helper command, so no stated test-quality failure is introduced.
Microshift Test Compatibility ✅ Passed The pull-request diff adds no Ginkgo tests or test declarations; it changes only helpers and rollout code, so the MicroShift test compatibility check is not applicable.
Single Node Openshift (Sno) Test Compatibility ✅ Passed The PR adds no Ginkgo e2e tests. Its only test-path change updates oc registry login in a helper and adds no It, Describe, Context, or When declarations.
Topology-Aware Scheduling Compatibility ✅ Passed The complete PR diff changes only devex and test helper Go files; it adds no manifests, operator/controller code, or topology-sensitive scheduling constraints.
Ote Binary Stdout Contract ✅ Passed The PR diff adds no process-level stdout writes or OTE suite-entrypoint changes; the test-helper change only adds an oc registry argument.
Ipv6 And Disconnected Network Test Compatibility ✅ Passed The PR diff adds no Ginkgo e2e tests or test files. Its only test-tree change targets the cluster-internal registry hostname, which the check exempts.
No-Weak-Crypto ✅ Passed The complete PR diff adds no MD5, SHA1, DES, RC4, Blowfish, ECB, custom crypto, or secret/token timing comparisons.
Container-Privileges ✅ Passed The PR changes only Go helpers and modifies no container/Kubernetes manifests; the patch adds no privileged, host namespace, SYS_ADMIN, root, or allowPrivilegeEscalation settings.

Remove or call createImagestream.

Static analysis reports that createImagestream is unused. If golangci-lint runs in CI, this error can fail the check. Delete the obsolete helper or connect the active setup path to it.

The setDeploymentReplicas and setMachineConfigPoolPauseState sometimes
conflict with cluster operations. This will retry these operations in
the event of a conflict.

Because on-cluster layering is now in GA, this hard featuregate
requirement is no longer needed.

When oc registry login is used with the internal image registry, the
internal image registry hostname must be used if the long-lived pull
secret is to be used from inside the cluster. Adding the --registry flag
and providing the internal hostname will ensure that the pull secret
uses the internal hostname instead of the default, which is the external
hostname.

Replace context.TODO() with a caller-provided context.Context throughout
the rollout call chain. All entry points now accept a context that is
forwarded to every API call inside the package. This also adds a
top-level context to the mco-builder and mco-push commands that is
threaded down to each of the rollout calls.

This also tracks which scale-down steps in ReplaceMCOImage have completed and
ensures that the scale-down steps will be reverted if the context is
cancelled or the deadline has been exceeded. (This was requested by CodeRabbit)
