Minimal Wolfi-based Rust image for building Rust applications.
Download this Image
The image is available on cgr.dev:
docker pull cgr.dev/chainguard/rust:latest
Image Variants
Our latest tag uses the most recent build of the Wolfi Rust package.
This image contains the tools needed to build Rust code.
This includes:
rustccargorustdocrustlldb- And more!
This image also includes a shell for compatibility with most cargo package installations.
This image is not intended to be used as a runtime image, only as a build tool.
Rust Version
This will automatically pull the image to your local system and execute the command rustc --version:
docker run --rm cgr.dev/chainguard/rust --version
You should get output similar to this:
rustc 1.67.1 (d5a82bbd2 2023-02-07) (built from a source tarball)
Application Setup for End Users
For runtime, you can use a multi-stage Dockerfile or similar technique to run your compiled binaries on
an even more slimmed down image.
The exact image will depend on your application, but static or glibc-dynamic should work.
This sample Dockerfile shows how to get a basic build up and running on glibc-dynamic.
There's one build argument, PACKAGE, that needs to be replaced with the name of your rust package.
ARG PACKAGE=myapp
FROM cgr.dev/chainguard/rust as build
WORKDIR /app
COPY . .
RUN cargo build --release
FROM cgr.dev/chainguard/glibc-dynamic
COPY --from=build --chown=nonroot:nonroot /app/target/release/${PACKAGE} /usr/local/bin/${PACKAGE}
CMD ["/usr/local/bin/${PACKAGE}"]
$ docker build -t foo --build-arg PACKAGE=shop .
