musl image

[mcandre]

Would be nice to feature a :musl tag for building musl Rust binaries!

As an example, see https://github.com/mcandre/docker-linux-rust/blob/master/musl.Dockerfile

This is blocked on official dists targeting musl.

The playground would also make good use of this :-)

Right now, we use an unofficial image.

[mbrubeck]

https://github.com/japaric/cross has Docker images that include musl toolchains/libraries.

I would also love to see an official image to link binaries against musl, since they are truly statically linked. Currently I'm using ekidd/rust-musl-builder which might be a good base to use.

@sfackler Is there a tracking issue that we can link this issue to? :)

[sfackler]

I'm not aware of one off the top of my head.

rust 1.35 added a support for the musl distros
Could it help in resolving this issue?

[sfackler]

It looks like rustup doesn't yet publish a musl-based version, so we'd need to get that done first: rust-lang/rustup#1053

[mati865]

It's less convenient but you can use tarballs until rustup is fixed: https://forge.rust-lang.org/other-installation-methods.html#standalone

[DrSensor]

Seems like rust-lang/rustup#1053 just resolved recently

[sfackler]

Great! It appears that a musl build isn't actually published yet, so we may need to wait for the next rustup release.

[softprops]

Whats the status on this?

[mati865]

There is no change on Rustup situation. It can only be installed using tarballs.

[DrSensor]

@sfackler, what is the blocker this time? 🤔

[sfackler]

There is no musl build of rustup yet.

[ZapAnton]

Rustup version 1.19 was just published with the rust-lang/rustup#1882 resolved
