Remove unused Docker containers and images
Raw
remove-docker-containers.md

Delete all containers

$ [sudo] docker ps -q -a | xargs [sudo] docker rm

Notes

-q prints only the container IDs, -a prints all containers.

Notice that it uses xargs to issue a remove container command for each container ID.

Delete all untagged images

$ [sudo] docker rmi $([sudo] docker images | grep "^<none>" | awk '{print $3}')

Notes

awk must use a single quote or the curly brackets will be interpreted by the shell.
