How do you keep docker/podman containers up-to-date? (lemmy.world)

I used to simply use the 'latest' version tag, but that occasionally caused problems with breaking changes in major updates.

I'm currently using podman-compose and I manually update the release tags periodically, but the number of containers keeps increasing, so I'm not very happy with this solution. I do have a simple script which queries the Docker Hub API for tags, which makes it slightly easier to find out whether there are updates.

I imagine a solution with a nice UI for seeing if updates are available and possibly applying them to the relevant compose files. Does anything like this exist or is there a better solution?

WatchTower can auto uodate your container or notify you when an update is available, I use it with a Matrix account for notifications

Yes, https://containrrr.dev/watchtower/ is a great tool. Used it myself for a whole now.

+1 for watchtower. I've been using it for about a year now without any issues to keep anywhere from 5 to 10 Docker containers updated.

Sorry if it's obvious, but I don't see a way to use Matrix for notifications on their documentation and my searching is coming up blank. Do you by chance have a tutorial for this?

Here is how I did it:

docker run -d \
  --name watchtower \
  -v /var/run/docker.sock:/var/run/docker.sock \
  -e WATCHTOWER_NOTIFICATION_URL=matrix://username:password@domain.org/?rooms=!ROOMID:domain.org \
  -e WATCHTOWER_NOTIFICATION_TEMPLATE="{{range .}}[WatchTower] ({{.Level}}): {{.Message}}{{println}}{{end}}" \
  containrrr/watchtower

Edit: I created a pull request to the WatchTower documentation, here: https://github.com/containrrr/watchtower/pull/1690

Thank you very much! I'll get this set up on mine.
