Attempting to stop/rm/kill the containers results in something like:

Error response from daemon: cannot stop container: netstats: Cannot kill container b7ce6fe3a5cb3f5374e70c35440688ddf836bc831350711e6c53ddcc551765bb: connection error: desc = "transport: dial unix /var/run/docker/containerd/docker-containerd.sock: connect: connection refused": unknown
