Bash script to stop all Docker services and remove unused data
When developing with Docker you will likely accumulate a large number of unused images. These can consume a significant amount of space (have a look using docker system df). This can be a particular issue when running Docker in a virtual environment where disk space is limited.
From time to time you may want to clean up your Docker development environment. This script stops all Docker services, stacks and containers, leaves the swarm (if applicable) and removes unused data, so please ensure you don't have important data in your containers before using the script!
All containers, networks, images and build caches are removed. Volumes are retained but can be removed by passing "--volumes" to the script as an argument. Dangling images (those without a tag) can be removed by passing "--all". See https://docs.docker.com/engine/reference/commandline/system_prune/ for more information.
❗ Use with Docker 17.06.1 or higher. The script will remove all volumes without warning for earlier versions. Use at own risk!
- Download and save in your home directory
- Run using
~/docker-clear - Pass
--volumesto the script to remove all volumes - Pass
--allto the script to remove all images and not just dangling images
The script calls docker rather than sudo docker. The following commands add the current user to a docker Unix group. Members of this group can run Docker commands without using sudo. See https://docs.docker.com/install/linux/linux-postinstall/#manage-docker-as-a-non-root-user for more information and security implications.
$ sudo groupadd docker
$ sudo usermod -aG docker $USER
Log out and back in after running the above.
