Docker - How to cleanup (unused) resources

The guide shows how to cleanup resources, that can be done once in a while.

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 }')

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")

Resize disk space for docker vm

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