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. > [wikipedia.org/wiki/Rust_(programming_language)](https://en.wikipedia.org/wiki/Rust_%28programming_language%29)  # 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: ```dockerfile FROM rust:1.23.0 WORKDIR /usr/src/myapp COPY . . RUN cargo install CMD ["myapp"] ``` Then, build and run the Docker image: ```console $ 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 compile, but not run your app inside the Docker instance, you can write something like: ```console $ docker run --rm --user "$(id -u)":"$(id -g)" -v "$PWD":/usr/src/myapp -w /usr/src/myapp rust:1.23.0 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 `target/release/myapp`. # Image Variants The `rust` images come in many flavors, each designed for a specific use case. ## `rust:` This is the defacto image. If you are unsure about what your needs are, you probably want to use this one. It is designed to be used both as a throw away container (mount your source code and start the container to start your app), as well as the base to build other images off of. This tag is based off of [`buildpack-deps`](https://registry.hub.docker.com/_/buildpack-deps/). `buildpack-deps` is designed for the average user of docker who has many images on their system. It, by design, has a large number of extremely common Debian packages. This reduces the number of packages that images that derive from it need to install, thus reducing the overall size of all images on your system. ## `rust:-slim` This image does not contain the common packages contained in the default tag and only contains the minimal packages needed to run `rust`. Unless you are working in an environment where *only* the `rust` image will be deployed and you have space constraints, we highly recommend using the default image of this repository. # License View [license information](https://www.rust-lang.org/en-US/legal.html) for the software contained in this image. As with all Docker images, these likely also contain other software which may be under other licenses (such as Bash, etc from the base distribution, along with any direct or indirect dependencies of the primary software being contained). Some additional license information which was able to be auto-detected might be found in [the `repo-info` repository's `rust/` directory](https://github.com/docker-library/repo-info/tree/master/repos/rust). As for any pre-built image usage, it is the image user's responsibility to ensure that any use of this image complies with any relevant licenses for all software contained within.
