A collection of handy Docker CLI

docker-useful-commands.md

Delete all containers

docker ps -q -a | xargs docker rm

-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

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

awk must use a single quote (this filters all image IDs)

Delete Unused Containers

docker rm $(docker ps -aq -f status=exited)
