Docker clients are unable to connect to docker and app nodes show all pods in an "Unknown" status
Issue
-
Docker service is running but clients are unable to connect to docker (e.g.
docker ps)# docker ps Cannot connect to the Docker daemon. Is the docker daemon running on this host? -
All pods are in an "Unknown" state except for the Twistlock pod which is in a "NodeLost" state.
