Installing and Executing Rust Code via Docker

The best way to try new technologies without having clutter? Docker.

This article is about how to install and run Rust code via Docker.

• Create a new directory in the host machine. Let's call it "my-rust-app"
• Create a very simple Dockerfile with the following lines

  # pull the latest version of Rust
  FROM rust:latest
  
  # change our work dir to /usr/myrustapp
  WORKDIR /usr/myrustapp
  
  # copy all the files in current dir to the work dir
  COPY . .
  
  # compile and run Rust script
  CMD ["cargo", "run"]
  

• Create a file called Cargo.toml and pass the following lines to the file.

  [package]
  name = "hello_world"
  version = "0.0.0"
  authors = ["Your Name"]
  edition = "2019"
  

• Create a directory src and a file main.rs within it. Here's the content of the main.rs.

  fn main() {
      println!("Hello, World!");
  }
  

• Open up a Terminal and execute the following commands.

  # build the image from the docker file
  docker build -t my-rust-img [path_to_the_dockerfile]
  
  # create and run a container from the image
  docker run -it --rm --name my-rust-container my-rust-img
  

• The Rust script should be compiled and executed
