Delete all docker images on your system:

docker rmi $(docker images -a -q)

This will:

• Use docker images -a -q to list all docker image IDs
• Pass the list of IDs to docker rmi to remove them

A few things to note:

• This will delete all images, not just unused ones, so be careful running this if you have images you want to keep
• You may need to add sudo before the command or run as root user
• To delete unused/dangling images instead, you can use: docker image prune

Some other useful docker cleanup commands:

• Delete all stopped containers: docker container prune
• Delete all networks not used by at least one container: docker network prune
• Delete all build cache: docker builder prune
