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?

For sure, just stacking turtles all the way down... 🐢 It's definitely overkill for a home lab, but I'm an infra engineer, and it's what I use daily, so setting it up was worth it because I'm already really familiar with the stack. That said, I do absolutely love having declarative setup at home because I'll sometimes go months without touching things. Before I spent the time to make it declarative, I'd frequently forget how I set certain things up and waste time redoing, or figuring out where I left off. Now I just check commit history and I'm always moving forward.
