On a real cluster every operator-emitted Event is rejected by the API server: Server rejected event (will not retry!) ... User "system:serviceaccount:etcd-operator-system:etcd-operator-controller-manager" cannot create resource "events" in API group "events.k8s.io", so kubectl describe etcdcluster always shows Events: <none>. The recorder wired in SetupWithManager via mgr.GetEventRecorder writes events.k8s.io/v1 Events, but role.yaml only grants events verbs in the core ("") API group — envtest does not enforce RBAC, so tests never catch this. This adds an events.k8s.io events create;patch RBAC marker (the two verbs the client-go tools/events broadcaster uses) and regenerates config/rbac/role.yaml. Verified with go build ./... and go test ./internal/... ./api/....

The recorder returned by mgr.GetEventRecorder writes events.k8s.io/v1
Events, but role.yaml only granted events verbs in the core ("") API
group, so the API server rejects every operator-emitted Event on real
clusters (envtest does not enforce RBAC):

  Server rejected event (will not retry!) ... cannot create resource
  "events" in API group "events.k8s.io"

Add an events.k8s.io events create;patch RBAC marker (the two verbs the
client-go tools/events broadcaster uses) and regenerate role.yaml.

Hi @xrl. Thanks for your PR.

I'm waiting for a etcd-io member to verify that this patch is reasonable to test. If it is, they should reply with /ok-to-test on its own line. Until that is done, I will not automatically test new commits in this PR, but the usual testing commands by org members will still work.

Regular contributors should join the org to skip this step.

Once the patch is verified, the new status will be reflected by the ok-to-test label.

I understand the commands that are listed here.

…d Role

The overlay role.yaml predates fix etcd-io#391 (events/v1 recorder writes to
events.k8s.io, not core/v1); without this rule every operator Event is
rejected in the namespace-scoped deployment.

The recorder returned by mgr.GetEventRecorder writes events.k8s.io/v1
Events, but role.yaml only granted events verbs in the core API group,
so every TLSReady event (including the new ClientCABroadTrust warning)
was silently dropped. Mirrors the standalone fix in etcd-io#391; whichever
lands first, the other rebases to a no-op.
