As an anti-Big Tech self-hoster, I don't like using GitHub to build and store my Ublue/Bluebuild container images.

I'm thinking of doing the building on my own machine and pushing the image to a self-hosted container registry. The bluebuild cli makes this easier. For a self-hosted container registry I can use Harbor.

I would write a script that fetches the latest version from my Codeberg repo, runs something like bluebuild build -v --push --registry $HARBOR_REGISTRY recipes/recipe.yml locally, and sends the log output to a file for debugging purposes.

I would have the script run as a systemd service with a daily timer. If I use a systemd service then I wouldn't necessarily have to store the log output to a file, as I could view it with journalctl -xeu bluebuild-build.service, but it might be nice to have separate log files in addition to that.

This way I can self-host it without having to fiddle with Gitea or Codeberg CI.
