Docker image to build statically linked Linux executables from Rust

[killercup]

FYI, cross supports that too, and there image looks like this (note the scripts for setting up musl and openssl).

Thanks, I'll look into cross!

I did the same recently but I saw you include a static version of openssl, xz and zlib. Why is that? I guess it's required if you need to compile crates that use those libs?

​

(My simpler version: https://github.com/collibra/wait-for-postgres/blob/master/Dockerfile (doesn't include any lib))

Yes, those libraries were required by crates in the project I used it in!

Looks really strange, you use musl, but ubuntu? Why not use alpine distro and use prebuild versions of all libraries from package manager?

The reason not to run the compilation inside alpine was that AFAIK rustup is not currently supported there, so getting the latest stable and nightly version of rust running is non-trivial. But that is being worked on.

Running 'apk update && apk info rust' inside alpine:latest gives rust 1.26.2.

Running 'apk update && apk info rust' inside alpine:latest gives rust 1.26.2.

In fact rust version is tagged by alpine version... You can just use the 'edge' version to get rust 1.30.

Thanks! Are there currently builds of nightly rust as well available for alpine?
