#### Network
- EndpointSlices: If upgrading a cluster with EndpointSlices already enabled, any EndpointSlices that should be managed by the EndpointSlice controller should have a `endpointslice.kubernetes.io/managed-by` label set to `endpointslice-controller.k8s.io`.

- The `PersistentVolumeLabel` admission controller in the API server is deprecated.

  - The replacement is running a cloud-specific controller-manager (often referred to as `cloud-controller-manager`) with the `PersistentVolumeLabel` controller enabled. This new controller loop operates as the `PersistentVolumeLabel` admission controller did in previous versions.

  // honor this field as long as the requested duration is not greater than the
  // maximum duration they will honor per the --cluster-signing-duration CLI
  // flag to the Kubernetes controller manager.
  //
  // Certificate signers may not honor this field for various reasons:
  //
  //   1. Old signer that is unaware of the field (such as the in-tree
  //      implementations prior to v1.22)

## Known Issues

* The deprecated `--service-account-private-key-file` flag has been removed from the cloud-controller-manager. The flag is still present and supported in the kube-controller-manager. ([#65182](https://github.com/kubernetes/kubernetes/pull/65182), [@liggitt](https://github.com/liggitt))

- kube-controller-manager currently needs a writable `--cert-dir` (default is `/var/run/kubernetes`) for generating self-signed certificates, when no `--tls-cert-file` or `--tls-private-key-file` are provided.
- The `system:kube-controller-manager` ClusterRole lacks permission to `get` the `configmap` extension-apiserver-authentication. kube-controller-manager errors if run with a service account bound to the clusterrole.

The above policies reject unauthenticated traffic at the ztunnel unless its destination is port 9090. For more complete examples, read through the [test cases](../../pilot/pkg/serviceregistry/kube/controller/ambientindex_test.go) in the `TestRBACConvert` function.
