Delete the image operation of none in docker images

Since I usually use the docker build command to generate an image, sometimes due to frequent code updates, a lot of none images will be generated. Recently, I want to clear them out.

So I wrote the following script:

docker ps -a | grep "Exited" | awk '{print $1 }'|xargs docker stop
docker ps -a | grep "Exited" | awk '{print $1 }'|xargs docker rm
docker images|grep none|awk '{print $3 }'|xargs docker rmi

Supplement: Docker deletes all none images or stopped containers

After repeated builds in docker, many none images will remain. The following command deletes all none images in one click.

docker rmi `docker images | grep '<none>' | awk '{print $3}'`

A simpler way

docker rmi `docker images -q -f dangling=true`

or

docker rmi $(docker images -q -f dangling=true)

Remove all stopped containers

docker rm $(docker ps -a -q)

The above is my personal experience. I hope it can give you a reference. I also hope that you will support 123WORDPRESS.COM. If there are any mistakes or incomplete considerations, please feel free to correct me.
