docker rmi image_name

You can find all the images that match a pattern using a combination of docker images and grep.

Once you're satisfied, you can delete them by using awk to pass the IDs to docker rmi.

To find the images:

docker ps -a |  grep "pattern"

To remove the images:

docker images | grep "pattern" | awk '{print $1}' | xargs docker rm

All the Docker images on a system can be listed by adding -a to the docker images command.

Once you're sure you want to delete them all, you can add the -q flag to pass the Image ID to docker rmi:

To list the images:

docker images -a

To remove the images:

docker rmi $(docker images -a -q)

docker rmi $(docker images --filter "dangling=true" -q --no-trunc)
