With a bit of luck, you should be able to just copy your application binary from `target/x86_64-unknown-linux-musl/release`, and install it directly on any reasonably modern x86_64 Linux machine. In particular, you should be able make static release binaries using TravisCI and GitHub, or you can copy your Rust application into an [Alpine Linux container][]. See below for details!
## Caching builds
You may be able to speed up build performance by adding the following `-v` commands to the `rust-musl-builder` alias:
```
-v cargo-git:/home/rust/.cargo/git -v cargo-registry:/home/rust/.cargo/registry
```
You will also need to fix the permissions on the mounted volumes:
```sh
rust-musl-builder sudo chown -R rust:rust /home/rust/.cargo/git /home/rust/.cargo/registry
```
## How it works
`rust-musl-builder` uses [musl-libc][], [musl-gcc][], and the new [rustup][] `target` support. It includes static versions of several libraries:
