I\'m reading a book on docker. It is a couple of years old.

I\'ll cite:

If you want to get rid of all your stopped containers, you can use
the output of          


        

Answer 1

Actually its an rights issue.... the error message:

Got permission denied while trying to connect to the Docker daemon socket at unix://

Tells you that you cant connect to you docker daemon which is running under root. You should decide if you want to use docker with # sudo or as root user.

Manage Docker as a non-root user

Further as said the docker rm complains about no images found for deletion therefore it wouldn't possible to delete images.

The command docker rm $(docker ps -aq -f status=exited) is just fine with newest docker version 18.09.0 but you could use docker container prune as well that is the more interactive way.
