[Build alpine packages in a temporary container] Did you ...

[oliv3r]

There's a project https://gitlab.com/esbs/package_builder-alpine/ that does exactly what you want :) either use that container, or clone the container so you have a local easily accessible shell script.

The only "issue" is that if you have (unavailable) dependencies, you need to get those in the container as well, as, well abuild deps can't get it otherwise. But that's your typical chicken and egg problem anyway. Upstream dependencies first ;)

Hope that helps and can reduce your 'quite long' page to a few lines :)
