Packaging your Rust CLI tool

There are a few things that are essential when packaging your Rust tool for distribution. This guide will walk you through the process of creating a distributable binary as well as creating a container image for your tool.

Creating a distributable binary on Linux

The first step is to create a distributable binary. This is a binary that can be run on any Linux system without any dependencies. This is done by compiling your Rust code with the musl target. This target is a Linux target that is statically linked. This means that all the dependencies are included in the binary itself.

To compile your Rust code with the musl target, you need to install the musl target for Rust. You can do this by running the following command in a Debian based Linux distribution:

sudo apt-get install -y musl-tools

Once you have the musl target installed, you can compile your Rust code with the musl target by running the following command:

cargo build --release --target x86_64-unknown-linux-musl

This will create a binary in the target/x86_64-unknown-linux-musl/release directory. This binary can be run on any Linux system without any dependencies.

Creating a distributable binary on OSX

You can create a binary for OSX by running the following command:

cargo build --release

This will create a binary in the target/release directory. This binary can be run on any OSX system without any dependencies.

Creating a container image

To create a container image you must create a Dockerfile. Make sure that the right version of Rust is used as a base image. You can find the right version of Rust on the Rust website. You can also use the rustup tool to install the right version of Rust.

Once you ensure the right version of Rust, make sure that your container can run from the terminal using the CMD instruction. This will allow you to run your container as if it was a normal binary.
