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?

    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:[email protected]/?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
