I use [Watchtower](https://github.com/containrrr/watchtower) to automatically update the docker images I use. After leaving it for several months, I've realized that I have been storing over 100GB of old docker images. I needed a way to automatically purge old images and [Systemd Timers](https://opensource.com/article/20/7/systemd-timers) is the solution.
