Alpine version

[ScottPierce]

An alpine version would be beneficial

[geek-at]

won't work because the github runner is not musl compatible. I tried on a barebone alpine installation

[williamdes]

I did try and here is the diff anyone can re-use

@williamdes so the diff you shared, does that work? Why not open a PR?

@williamdes so the diff you shared, does that work? Why not open a PR?

Well as you can see on the output there is still 2 things I can not fix, if you find how to do I will open a pull-request :)

[geek-at]

Another approach would be to add libc. I saw it in a different project the other day: https://github.com/disaster37/alpine-minio/blob/master/Dockerfile#L38

Basically they're patching libc into alpine to be able to run minio. Could work with the runner too

[williamdes]

Still no success 😟
