Docker - How to cleanup (unused) resources

Once in a while, you may need to cleanup resources (containers, volumes, images, networks) ...

Stop all containers

$ docker kill $(docker ps -q)

delete volumes

// see: https://github.com/chadoe/docker-cleanup-volumes

$ docker volume rm $(docker volume ls -qf dangling=true)
$ docker volume ls -qf dangling=true | xargs -r docker volume rm

delete networks

$ docker network ls  
$ docker network ls | grep "bridge"   
$ docker network rm $(docker network ls | grep "bridge" | awk '/ / { print $1 }')

remove docker images

// see: http://stackoverflow.com/questions/32723111/how-to-remove-old-and-unused-docker-images

$ docker images
$ docker rmi $(docker images --filter "dangling=true" -q --no-trunc)

$ docker images | grep "none"
$ docker rmi $(docker images | grep "none" | awk '/ / { print $3 }')
$ docker rmi -f $(docker images -aq)
$ docker rmi $(docker images -q)

remove docker containers

// see: http://stackoverflow.com/questions/32723111/how-to-remove-old-and-unused-docker-images

$ docker ps
$ docker ps -a
$ docker rm $(docker ps -qa --no-trunc --filter "status=exited")
$ docker rm $(docker ps -a -q)
