bruceadams/rustup-musl repository overview

⁠rustup-musl

I didn't find other Rust/musl Docker image setups that I was happy with. This is as simple as I was able to get working. The hard part was being able to use the rustls crate. The underlying problem came from the ring crate, which bundles c and c++ code.

The rmusl.sh script included in this repo just works on macOS, which is really nice. I expect it to work on a Linux host as well. It successfully caches crate downloads by sharing the cargo cache directories between the Docker container and the host system.

By default, rmusl.sh will run cargo build --release --target x86_64-unknown-linux-musl in the context of the current working directory. The output of the build will appear in target/x86_64-unknown-linux-musl/release/
