Have you ever had a full hard drive because of Docker? I had. All those old Docker containers, images, and volumes take up so much space. I used commands like
docker stop $(docker ps -a -q) and
docker rm $(docker ps -a -q) to remove all containers and images.
But newer Docker versions (Docker with API version 1.25+) have this handy cleanup command:
docker system prune --volumes
It cleans up all stopped containers, unused networks, dangling images, and the build cache. The
--volumes flag also removes all unused volumes. You can skip the "are you sure" prompt by using the
Beforehand, you will want to stop all containers using this command:
docker container stop $(docker container ls -aq)
And voilá! You have a clean local Docker installation.
- Find out how much space Docker takes on your system with:
docker system df
- Use the
untilfilter to only clean up stuff created more than, e.g., two days ago:
docker system prune --filter "until=48h"(Docker API version 1.28+; use
docker versionto find out the versions of your client and daemon)
- Only clean up containers created more than two days ago:
docker container prune --filter "until=48h"
