📝 Summary

Summary by CodeRabbit

  • Bug Fixes
    • Dex configurations that enable OpenShift OAuth are rejected on non-OpenShift clusters. SSO is marked as failed, and the configuration error is reported in the reconciliation status.
    • OpenShift OAuth configurations continue to work on OpenShift clusters. Other Dex connector configurations, including GitHub connectors, remain available on non-OpenShift clusters.

Walkthrough

The operator now rejects Dex configurations that enable OpenShift OAuth on non-OpenShift clusters. Unit and end-to-end tests cover the rejection. Other end-to-end tests use GitHub connector configurations or OpenShift-specific labels.

Changes

Dex SSO validation

Layer / File(s) Summary
Cluster validation and unit coverage
argocd-operator/controllers/argocd/sso.go, argocd-operator/controllers/argocd/sso_test.go
reconcileSSO marks SSO as Failed and returns an illegal-configuration error when OpenShift OAuth is enabled on a non-OpenShift cluster. Unit tests cover both cluster conditions.
End-to-end Dex coverage
test/openshift/e2e/ginkgo/parallel/1-143_dex_OpenshiftOAuth_test.go, test/openshift/e2e/ginkgo/parallel/1-007_validate_volume_mounts_test.go, test/openshift/e2e/ginkgo/parallel/1-042_restricted_pss_compliant_test.go, test/openshift/e2e/ginkgo/parallel/1-050_validate_sso_test.go, test/openshift/e2e/ginkgo/parallel/1-095_validate_dex_clientsecret_test.go, test/openshift/e2e/ginkgo/parallel/1-098_validate_dex_clientsecret_deprecated.go
An xKS test checks the failed phase, SSO status, and reconciliation condition for OpenShift OAuth. Other Dex tests use GitHub connectors or carry the openshift label.

Namespace ownership assertion

Layer / File(s) Summary
Managed-by label expectation
test/openshift/e2e/ginkgo/sequential/1-064_validate_tcp_reset_error_test.go
The namespace management assertion now expects the argocd-027 instance name.

🟡 Minor · Give operators an actionable remedy. · sso.go:53-71

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Give operators an actionable remedy.

When OpenShiftOAuth is already true on a non-OpenShift cluster, the rejection message tells the operator to set it. Because the message is returned and appears in the Reconciled condition, this can direct the operator to repeat a no-op change instead of using an OpenShift cluster or disabling the option.

Suggested fix
-errMsg = "openShiftOAuth is only supported on OpenShift clusters. Please set the openShiftOAuth configuration."

🎯 Functional Correctness | 🟠 Major | ⚡ Quick win

Update the unit test's expected error message.

TestReconcile_illegalSSOConfiguration still expects “Please set the openShiftOAuth configuration.” This branch now returns “Please disable the openShiftOAuth configuration.” Because the test compares errors with assert.Equal, the non-OpenShift case fails. Update the expected error to match the intended message.
