Anything else?

I am simply an outside observer, admittedly I don't even use this software.
With that said your Dockerfile was linked to me as a meme as it is running a version of Alpine that has been out of support since 2021.

Just a heads up, feel free to insta close this but you might want to think about a more scratch base or bumping Alpine or if this logic is not used in your workflow removed from the repo.

No problem! Did you want to push a PR or would you like one of us?

It's a small fix, but I'd like to give you the opportunity to do the PR before we push one.
