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?

I combine 3 options:

Watchtower updates most containers. They never break. If it leads to some breaking, it goes to the second option.
Update script that update the whole stack from portainer webhook. This did fix the only stack that used to give me issues with watchtower. The other stack is watchtower itself.
Manual update. Only for Homeassistant. I want to make sure to know about breaking changes. So I update it when I can and I read the patch notes.

It works for my around 100 containers.
