Docker: Cleanup (Remove all exited containers and dangling images)

docker-cleanup.sh

#!/bin/bash

docker rm $(docker ps -q -f status=exited)
docker rmi $(docker images -q -f dangling=true)

https://github.com/spotify/docker-gc

Did not worked for Docker for Windows:

unknown shorthand flag: 'q' in -q
See 'docker rm --help'.

@RSwarnkar, I had a similar issue, my problem got solved by this:

Basically, if you try
docker rmi $(docker images -q -f dangling=true)
you'll get that error, because $(docker images -q -f dangling=true) is a linux command. You'll need to change it to something like this:

FOR /f "tokens=*" %i IN ('docker images -q -f dangling=true') DO docker rmi %i

Hope this helps you out.
