It is believed that many inexperienced people have no idea about how to delete containers and images in docker. Therefore, this article summarizes the causes and solutions of the problem. Through this article, I hope you can solve this problem.

Delete all closed containers

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

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

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

Delete all dangling data volumes (that is, useless volume):

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

Clean up the garbage in the container

Docker system df-v

You can use this to find the exception container or execute the du command in the relevant directory, such as:

Cd / var/lib/docker/overlay2du-max-depth=1-h. / cd / var/lib/docker/containersdu-- max-depth=1-h. /

Then clean up any container that takes up too much, including the log files.

Clean up docker log files

Ls-lh $(find / var/lib/docker/containers/-name *-json.log)

List the log file size separately. Clear the log file

Truncate-s 0 / path/to/your/textfile
