Hey guys, just sharing a quick script that I saved here years ago about cleaning all docker images/containers/volumes:
#!/bin/bash # Kill all running containers. docker kill $(docker ps -q) # Delete all stopped containers. printf "\n>>> Deleting stopped containers\n\n" && docker rm $(docker ps -a -q) # Delete all untagged images. printf "\n>>> Deleting untagged images\n\n" && docker rmi $(docker images -q -f dangling=true) # Delete all images. printf "\n>>> Deleting untagged images\n\n" && docker rmi $(docker images -q) # Delete all volumes. printf "\n>>> Deleting volumes\n\n" && docker volume rm $(docker volume ls -q) # Remove all unused containers, networks, images (both dangling and unreferenced), and optionally, volumes. printf "\n>>> Deleting unused containers, networks, images and volumes\n\n" && docker system prune -a --volumes
