📝 WalkthroughSummary by CodeRabbit
WalkthroughThe change adds a dedicated controller for renewable metrics bearer tokens, updates ServiceMonitor authentication, removes the previous reconciliation path, wires the controller into runtime and e2e managers, and adds unit and end-to-end validation. ChangesMetrics token authentication
Estimated code review effort: 4 (Complex) | ~45 minutes Merge Risk: 🟡 Moderate · up to The PR changes metrics authentication to short-lived tokens, but upgrades can fail to replace the existing token because its Secret type cannot be changed in place. The legacy non-expiring credential may remain and rotation may not occur, so this migration issue should be fixed before merging. Sequence Diagram(s)sequenceDiagram

The legacy Secret migration uses Update to change an immutable field. Secret.type cannot change on update, so the service-account-token to Opaque migration is rejected by a real API server, and the fake-client test hides the failure.
controllers/operator_metrics_controller.go#L244-L310: replace the Secret through delete and recreate whenexistingSecret.Type != corev1.SecretTypeOpaque, and keep the recreate afterRequestTokensucceeds.controllers/operator_metrics_controller_test.go#L185-L239: cover the migration with an interceptor client or envtest so an immutable-type rejection fails the test.

Correct the renewal-lead comment.
operatorMetricsTokenRenewalPercent is 20, so bearerTokenRenewalLead() returns 12 minutes, which is one fifth of the lifetime. The comment states one third and "two thirds remain".

Migrate ServiceMonitor from deprecated bearerTokenSecret to authorization and manage a short-lived Opaque bearer token Secret via TokenRequest.
What type of PR is this?
/kind bug
What does this PR do / why we need it:
The operator metrics ServiceMonitor (
openshift-gitops-operator-metrics-monitor) previously relied on a non-expiringkubernetes.io/service-account-tokenSecret and the deprecatedbearerTokenSecretfield.This PR:
authorization(Bearer + credentials).OperatorMetricsTokenReconcilerto mint a short lived token via the Kubernetes TokenRequest API, store it in an Opaque Secret (token+expiry), renew before expiry, and replace the legacy SA token Secret on upgrade.ArgoCDMetricsReconcilerinto the dedicated controller.Have you updated the necessary documentation?
