Cleanup

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

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")
