If you’re a heavy user of docker you’ll for sure have a lot of trash in your /var/lib/docker
Check for your self:
sudo du -sh /var/lib/docker
To clean it, follow these simple steps (DISCLAIMER, This will stop and remove all the current containers):
- Remove the containers (and stopped too)
docker ps -a -q | xargs docker rm -f
- Remove all downloaded and build images
docker image ls -q | xargs docker image rm -f
- Remove all volumes
docker volume ls -q | xargs docker volume rm -f
