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

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?

I use podman auto-update command.

I'd also like to see what others use

I originally used this too, but in the end had to write my own python script that basically does the same thing and is also triggered by systemd. The problem I had was that for some reason podman sometimes thinks there is a new image, but when it pulls it just gets the old image. This would then trigger restarts of the containers because auto-update doesn't check if it actually downloaded anything new. I didn't want those restarts so had to write my own script.

Edit: but I lock the version manually though e.g. nextcloud 27 and check once a month if I need to bump it. I do this manually in case the upgrade needs an intervention.
