Docker Tips: How to Delete All Docker Containers and Images

It's time to start sharing some tips I've found along the way while using Docker. You may come upon a time where you will be required to clean up your Docker installation.

If you have used docker for any length of time you will start to notice unused containers and images laying around. Sometimes this can become a burden on your disk space or just an administrative hassle. Either way it is a quick and easy fix.

Before proceeding please be aware that these commands will nuke every non-running container and image that is not associated to a running container. You've been warned.

Option 1 - Delete all untagged Docker Images This was updated based on Matthew Torres's comment below as it is much easier to delete with the filtering flag Check out Docker's Filtering Docs for more information.

Option 2 - Delete all Docker Images

docker rmi $(docker images -q)
