What type of PR is this?

/kind bug

What does this PR do / why we need it:

This PR fixes a bug in the reconciliation of the GitOps Promoter's APIService. Before this fix, if an Argo CD CR was created with the promoter enabled and then another Argo CD CR was created where it was disabled, the APIService would be deleted. This was because there was no ownership check of the APIService and there can only be one of it in the cluster.

This PR fixes it by adding in a check to see if the Argo CD CR creates the service that is linked to the APIService. If for some reason that field is not set it does not delete for safety.

Test acceptance criteria:

  • Unit Test
  • E2E Test

How to test changes / Special notes to the reviewer:

  1. Create an Argo CD CR where the Promoter is enabled
  2. Ensure that APIService is created
  3. Create an Argo CD CR where the Promoter is disabled
  4. Make sure the APIService was not deleted

📝 Summary

Summary by CodeRabbit

  • Bug Fixes

    • Prevented one Argo CD instance from deleting an API service belonging to another instance.
    • Preserved API services when their referenced service is missing or does not match the expected namespace and name.
    • Improved cleanup error details for promoter API services.
  • Tests

    • Added coverage confirming API services remain intact when multiple Argo CD instances exist in different namespaces.
    • Added validation for cleanup behavior when instances have different promoter settings.
    • Verified API service updates when configuration changes.

Walkthrough

The APIService reconciler now checks ownership before operations and cleanup. Deletion receives the component name and ArgoCD resource. Tests cover multiple CRs in different namespaces and preserve the owned APIService.

Changes

Promoter APIService ownership protection

Layer / File(s) Summary
APIService ownership guard
argocd-operator/controllers/gitopspromoter/apiservice.go, argocd-operator/controllers/gitopspromoter/apiservice_test.go
APIService operations now require a non-nil referenced service with the expected namespace and generated promoter service name. DeleteAPIServices accepts the component name and ArgoCD resource and deletes only owned APIService objects. The update test now changes only the service port.
Cleanup wiring and multi-CR validation
argocd-operator/controllers/argocd/util.go, argocd-operator/controllers/gitopspromoter/apiservice_test.go
deleteClusterResources passes the API server component name and ArgoCD resource to DeleteAPIServices. The multi-CR test verifies that a disabled CR in another namespace does not delete an existing APIService. The setResourceWatches hunk has no functional effect.

Priority: ➖ Normal

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

Change: Bug fix

Merge Risk: 🔵 Low · up to a9636

The ownership change’s update test currently verifies a skipped reconciliation rather than an owned APIService update. Correcting the fixture will preserve coverage for future update regressions.

🟠 Major · Compare the full expected Service reference before deleting the APIService.

argocd-operator/controllers/gitopspromoter/apiservice.go:59-73
🩺 Stability & Availability | 🟠 Major | ⚡ Quick win

Compare the full expected Service reference before deleting the APIService. The fixed-name APIService stores a Service name derived from the CR name. A different disabled CR in the same namespace can pass the namespace-only guard and delete the APIService used by an enabled CR. Require matching Service name and namespace, and add a same-namespace multi-CR regression test. The owning CR will still delete the APIService because its generated Service reference matches.

🟡 Minor · Make the APIService fixture owned by the current CR. · apiservice_test.go:366-393

argocd-operator/controllers/gitopspromoter/apiservice_test.go:366-393
📐 Maintainability & Code Quality | 🟡 Minor | ⚡ Quick win

Make the APIService fixture owned by the current CR. The fixture uses not-a-real-namespace, so the ownership predicate fails before ReconcilePromoterAPIServerAPIService reaches the Service or CABundle update branch. Set Spec.Service.Namespace to cr.Namespace and Spec.Service.Name to generatePromoterResourceName(testCompName, cr) so the incorrect port exercises the owned update path.
