Monthly docker cleanup

Getting rid of docker containers can be a pain.Its been about 6 months I have been using docker to build images for development purposes.
I took at my free space and I have only a couple of gigs free (5 gigs to be exact).It was time to clean this shit up.

docker rm $(docker ps -a -q)
#This removes all docker containers which have exited

docker rmi $(docker images -q)
#This deletes all the docker images.
