$ docker container list -a

I noticed I had a large number of docker containers that weren’t being used. Fortunately docker makes it easy to single out a container from this list and remove all containers that were created before it.

docker ps -aq -f "before=widgets_web_run_32cb6f5d2d71" | xargs docker container rm

There are a bunch of handy filters that can be applied to docker ps. Nice for a bit of spring cleaning.
