Thanks for sharing this overview, Alex! :)
There is also docker system prune to remove all unused data (volumes, stopped containers, etc.).
docker system prune
Thank you, added by your recommendation to the article :) Used many times but forgot to mention.
This is almost true. Sometimes docker system prune will leave hanging and orphaned volumes. Specifically in the docker overlay dir.
Bonus of 'docker prune': it does not remove running services & related images.
