de feature gate. It can be used to tell kubeadm to use the local kube-apiserver endpoint for the kubelet when creating a cluster with "kubeadm init" or when joining control plane nodes with "kubeadm join".  The "kubeadm join" workflow now includes two new experimental phases called "control-plane-join-etcd" and "kubelet-wait-bootstrap" which will be used when the feature gate is enabled. This phases will be marked as non-experimental when ControlPlaneKubeletLocalMode becomes GA. During "kubeadm upgrade"...

  never enter the Succeeded phase may need to adapt their controllers. This is because as a consequence of 
  the change pods which use RestartPolicy=Always may end up in the Succeeded phase in two scenarios: pod 
  deletion and graceful node shutdown. ([#115331](https://github.com/kubernetes/kubernetes/pull/115331), [@mimowo](https://github.com/mimowo)) [SIG Cloud Provider, Node and Testing]
