We’re using beta6 of Docker for AWS (and therefore Docker 1.12.2-rc1), and this is the second time I’ve seen the Docker daemon apparently die on the manager:
~ $ docker ps
Cannot connect to the Docker daemon. Is the docker daemon running on this host?
Last time this happened, I ended up having to recreate the Swarm What’s the best way to recover from this situation, given that we don’t have root access to the manager? (or do we?)
