After using docker containers for a period of time, you will find that a lot of useless junk files have been stacked, such as terminated containers, limited images, chaotic storage, and so on.

Command docker system prune

Can be used to clean disks, delete closed containers, useless data volumes and networks, and dangling mirrors (that is, mirrors without tag).

Command docker system prune-a

Clean up more thoroughly, you can delete all Docker images that do not have containers. Note that these two commands will delete the containers you temporarily closed, as well as the Docker images that are not used for the time being.

Sometimes we need to clean up manually without the docker system command. Here are a few common commands:

1. Delete all closed containers

Docker ps-a | grep Exit | cut-d''- f 1 | xargs docker rm

two。 Delete all dangling images (that is, mirrors without tag)

Docker rmi $(docker images | grep "^" | awk "{print $3}")

3. Delete all dangling data volumes (that is, useless Volume)

Docker volume rm $(docker volume ls-qf dangling=true)
