I’ve just started looking at Docker. It’s a cool new technology that has the potential to make the management and deployment of distributed applications a great deal easier. I’d very much recommend checking it out. I’m especially interested in using it to deploy Mono applications because it promises to remove the hassle of deploying and maintaining the mono runtime on a multitude of Linux servers.

I’ve been playing around creating new images and containers and debugging my Dockerfile, and I’ve wound up with lots of temporary containers and images. It’s really tedious repeatedly running ‘docker rm’ and ‘docker rmi’, so I’ve knocked up a couple of bash commands to bulk delete images and containers.

Delete all containers:

sudo docker ps -a -q | xargs -n 1 -I {} sudo docker rm {}

Delete all un-tagged (or intermediate) images:

sudo docker rmi $( sudo docker images | grep '<none>' | tr -s ' ' | cut -d ' ' -f 3)
