There is a new feature in Docker 1.13.x called Docker container prune: docker container prune This will do what you want and should work on all platforms the same way.

There is also a Docker system prune, which will clean up containers, images, volumes, and networks all in one command.

Original Answer:

There has been some talk about a Docker cleanup command. You can find the information on this ticket: https://github.com/dotcloud/docker/issues/928

Until that command is available, you can string Docker commands together with other Unix commands to get what you need. Here is an example on how to clean up old containers that are weeks old:

$ docker ps --filter "status=exited" | grep 'weeks ago' | awk '{print $1}' | xargs --no-run-if-empty docker rm
