DEPRECATED

Due to #13 and various other breaking changes, we decided to not spend more time on this custom homemade script and head to more standard and usable solutions such as diun to get update notifications, which seems more fitting to our technical needs.

After 3 years of use in production, this script is now deprecated and will not be further maintained.

The script is licensed under the MPL 2.0 license. Feel free to reuse for any project as long as you respect this license.


docker-update-images

Script to update Docker images easily.

  • Checks image updates with DockerHub's API (without pulling)
  • Pulls new versions automatically from DockerHub
  • Rebuilds child images (and their children, and so on)
  • Automatically deletes old images
  • Automatically restarts updated services
  • All information concerning images are written in services.json
  • 250 lines of Python (including ~20% of comments), easy to read

Alpha stage, but used in production on 42l's servers.

Might receive some updates from time to time (see Issues).

Script diagram

Here's a drawio diagram representing the script's algorithm. It's not very up-to-date, but it should be enough for you to have an idea of how the script operates.
