- kubeadm: consider --bind-address or --advertise-address and --secure-port for control plane components when the feature gate WaitForAllControlPlaneComponents is enabled. Use /livez for kube-apiserver and kube-scheduler, but continue using /healthz for kube-controller-manager...

#### Docker runtime Known Issues

- Kernel crash with Aufs storage driver on Debian Jessie ([#27885](https://github.com/kubernetes/kubernetes/issues/27885))
  - Consider running the *new* [kubernetes node problem detector](https://github.com/kubernetes/node-problem-detector) to identify this (and other) kernel issues automatically.

the PVC is bound to a PV object. During the binding process, if a PVC has a `volumeAttributesClassName` field set, the controller will only consider volumes that have the same `volumeAttributesClassName` as the PVC. If the `volumeAttributesClassName` field is not set or set to an empty string, only volumes with empty `volumeAttributesClassName` will be considered.
