What is the metadata-action used for? (comparing against https://github.com/ephios-dev/ephios/blob/main/.github/workflows/docker.yml). And you probably need the permission stuff to write packages as well

Ok, the ephios action looks good. How do you use it? Do you create releases via github and then manually start the workflow or do you create tags via git locally and then push them to trigger it? I think it would be best if it automatically ran on release (https://docs.github.com/en/actions/using-workflows/events-that-trigger-workflows#release) but I'm not sure if we have the metadata available there.

We create releases in the GitHub webinterface, and this automatically triggers the workflow and creates the correctly tagged packages (https://github.com/ephios-dev/ephios/pkgs/container/ephios)

Ok, so just replace the current action with the ephios workflow file?
