## Removing stopped container
docker ps -a | grep Exited | awk '{print $1}' | xargs docker rm
## If you do not want to remove all container you can have filter for days and weeks old like below
#docker ps -a | grep Exited | grep "days ago" | awk '{print $1}' | xargs docker rm
#docker ps -a | grep Exited | grep "weeks ago" | awk '{print $1}' | xargs docker rm
## Removing Dangling images
## There are the layers images which are being created during building a Docker image. This is a great way to recover the spaces used by old and unused layers.
docker rmi $(docker images -f "dangling=true" -q)
## Removing images of perticular pattern For example
## Here I am removing images which has a SNAPSHOT with it.
docker rmi $(docker images | grep SNAPSHOT | awk '{print $3}')
## Removing weeks old images
docker images | grep "weeks ago" | awk '{print $3}' | xargs docker rmi
## Similarly you can remove days, months old images too.
