I was updating one of my docker containers this morning and received an error in the middle of the update process.  Unfortunately, I didn't record what that error said - I believe it was a connection refused error of some sort.   Since closing the update window, I've been receiving an error that the "Docker Service failed to start" and all of my containers are down.

 

At the bottom of the Dockers tab page, there are several error messages:

 

Warning: stream_socket_client(): unable to connect to unix:///var/run/docker.sock (Connection refused) in /usr/local/emhttp/plugins/dynamix.docker.manager/include/DockerClient.php on line 682
Couldn't create socket: [111] Connection refused
Warning: Invalid argument supplied for foreach() in /usr/local/emhttp/plugins/dynamix.docker.manager/include/DockerClient.php on line 866

Warning: Invalid argument supplied for foreach() in /usr/local/emhttp/plugins/dynamix.docker.manager/include/DockerClient.php on line 932

 

I tried stopping and restarting the Docker service, but that hasn't resolved things.  (When I change the "Enable Docker" setting to "No" and save the change, the "Status" flag in the top right corner never changes from "Running", so I'm not sure that it's ever actually trying to fully restart.  The Docker tab does go away though, so maybe it is.)

 

Perhaps something in the update process for the container I was updating corrupted my Docker file?

 

I've attached my diagnostics logs.

 

Any help would be greatly appreciated!

Looks like the docker image ran out of space, the system share exists on both disk1 and cache, if the docker image is on disk1 the disk is completely full, if that's the case I would recommend deleting that one and recreating the image on cache.

Thank you @JorgeB!   That did the trick.  Much appreciated!
