The feature

Hi Damon, just wanted to start with thanking you for this project, just started using it recently but it is pretty awesome!

For my feature: please consider adding at least one OCI label to the docker container. This would help those of us using a dependency manager like Renovate to automate updating containers. From the Renovate docs, the minimum that is needed is to add a LABEL to the Dockerfile pointing to this repo:

LABEL org.opencontainers.image.source="https://github.com/damongolding/immich-kiosk"

If you care to go one step further, I have a branch in my fork of immich-kiosk that updates the docker-release workflow to add a few more labels that I'd be happy to submit as a PR if you want or take and modify as you see fit for this project.

Happy to add some standardised labels!

I'll check out your fork.

I don't use the docker-release workflow anymore, I use ghcr-release one.

If you create a PR adding the labels I'll happily review and add them 😊

Sorry, should have paid more attention to which workflows were actually in use. Submitted #644 for you to look at when you get a chance. Thanks!
