## What it is
A set of Docker images for compiling fully static Rust binaries against musl-libc and musl-gcc, bundling static versions of common C libraries like OpenSSL and libpq. It enables distributing Rust applications as single executables that run on any modern Linux system or in Alpine containers.

## Use cases
- build static rust binaries with docker
- compile rust with openssl statically
- build diesel apps as single binaries
- create alpine linux rust containers
- cross-compile rust for musl target
- ship rust apps with no runtime dependencies

## When to avoid
- your dependencies work with rustls instead of OpenSSL
- you can use the cross tool for musl cross-compilation
- you need an actively maintained solution

## Facets
- artifact type: infra-config
- maturity: abandoned
- function: build-tool, container-runtime, compiler
- domain: developer-tools, programming-languages
- platform: rust, cli
- tags: musl, static-linking, cross-compilation, docker-images, release-builds, devops, containers, docker, linux
