What is Rust?
Rust is a systems programming language sponsored by Mozilla Research. It is designed to be a “safe, concurrent, practical language”, supporting functional and imperative-procedural paradigms. Rust is syntactically similar to C++, but is designed for better memory safety while maintaining performance.
How to use this image
Start a Rust instance running your app
The most straightforward way to use this image is to use a Rust container as both the build and runtime environment. In your
Dockerfile, writing something along the lines of the following will compile and run your project:
FROM rust:1.19.0 WORKDIR /usr/src/myapp COPY . . RUN cargo install CMD ["myapp"]
Then, build and run the Docker image:
$ docker build -t my-rust-app . $ docker run -it --rm --name my-running-app my-rust-app
Compile your app inside the Docker container
There may be occasions where it is not appropriate to run your app inside a container. To compiler, but not run your app inside the Docker instance, you can write something like:
$ docker run --rm --user "$(id -u)":"$(id -g)" -v "$PWD":/usr/src/myapp -w /usr/src/myapp rust:1.19.0 cargo build --release
This will add your current directory, as a volume, to the container, set the working directory to the volume, and run the command
cargo build --release. This tells Cargo, Rust’s build system, to compile the crate in
myapp and output the executable to
