Docker and kubelet are failing to start on TKGi nodes.
kubelet is failing due to unavailability of docker and docker is logging this error message in docker.stderr.log:
failed to start daemon: failed to dial "/run/containerd/containerd.sock": failed to dial "/run/containerd/containerd.sock": context deadline exceeded
This can be experienced on TKGi v1.11, 1.12 and 1.13.
This is a known issue and fixed in TKGi v1.12.5 and v1.13.3
