Cleanup Docker

Docker utils

Delete all containers
docker rm -v $(docker ps -qa)
-v remove the volume

Delete all images
docker rmi $(docker images -q)
docker rmi $(docker images -q -f "dangling=true")

Removes all containers running under Docker, so use with caution.
docker ps -a | awk '{print $1}' | xargs docker kill

Removing all Containers that are not running:
docker rm $(docker ps --filter "status=exited" -q --no-trunc)

-a is not needed when using --filter status=exited.
-f allows you to filter your list of printed containers (in this case we are filtering to only show exited containers)
-q prints just the container ids (without column headers)

Now this removes all the dangling non intermediate <none> images:
docker rmi $(docker images --filter "dangling=true" -q --no-trunc)
docker volume rm $(docker volume ls -q -f "dangling=true" )
