This repository contains the source code and the tooling to produce the Docker containers used by Crater and docs.rs to build third-party crates. The contents of this repository are released under the MIT license.

The images do not contain a Rust toolchain in them: you'll need to manually mount the toolchain(s) you want to use inside the container.

If your crate fails to build on Crater or docs.rs, you can:

• Open an issue with the names of the packages you need
• Send a PR adding the package names to the linux/packages.txt file

Note that the package needs to be available in the Ubuntu 22.04 archives.

This container is based on Ubuntu 22.04 and includes all the native dependencies used by Rust crates we know of. It's used as the build environment for the Crater and docs.rs projects.

You can pull this container by running:

docker pull ghcr.io/rust-lang/crates-build-env/linux:latest

This container is based on Ubuntu 22.04 and includes the minimum set of dependencies needed to compile simple Rust programs. It's used by the test suites of Crater and docs.rs and during local development.

You can pull this container by running:

docker pull ghcr.io/rust-lang/crates-build-env/linux-micro:latest

This work in progress container is based on Windows 2019. It's currently unused and unmaintained, and no automated builds for it are available.
