Create Alpine-based dotnet images

[dleeapho]

Alpine is a small footprint distro that is gaining wide adoption in Official images. Prereq is to get Alpine support for the dotnet runtime, libraries, and CLI.

This is one of the reasons I like golang, is that they have a golang:alpine docker image that is very small. There is now even a rust-musl-builder docker image. It would be nice if dotnet --native supported targeting musl too, so the binaries could be put on alpine images.

I know one of the things that's been blocking this is the absence of lttng-ust on Alpine, but guess what? It's available now!

Hello guys!

Is this still on the roadmap? It's a bit hard to understand the current status of https://github.com/dotnet/coreclr/issues/917.

Thanks!

@RTodorov, Yes Alpine support is being actively worked on although there is no set release date as of now.

Just pinging the old thread to see if we could have a good ol' status update. 😄
