How do you keep docker/podman containers up-to-date?
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 DIUN (docker image update notifier). You can watch tags with it and it will notify you when updates are available. I have it email me Saturday morning. I like it a lot more than watchtower.

This looks great. I was looking at Watchtower again a few days ago, but I don't want to auto update my containers, just get notified for updates. I usually just keep the RSS feed of the project in my feed reader, but diun looks like a proper solution. Thanks!
Huh, that’s actually way better than my current setup of spamming me on Telegram every time there’s an update
