How to cleanup Docker resources

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

Delete 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 #

$ 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 }')

Remove docker containers #

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

$ docker-machine create --driver virtualbox --virtualbox-disk-size "40000" default
