# Installation Guide

1. Get the code

git clone https://github.com/codewars/codewars-runner-cli

Downloads the entire project code from GitHub to your computer.

cd codewars-runner-cli

Moves into the project folder you just downloaded.

2. Docker

Easy Recommended

Prerequisites

Git Needed to download the project code from GitHub.
Docker Desktop Needed to build and run containers. Install it and keep it running in the background.

docker run --rm -it --entrypoint bash codewars/node-runner

Runs the built image as an actual container.

docker-compose run node-runner

Runs the command against the services defined in the compose file.

docker run --rm codewars/node-runner run -l javascript -c "console.log('I ran inside of Docker using NodeJS')"

Runs the built image as an actual container.

docker run --rm codewars/ruby-runner run -l ruby -c "puts 'I ran inside of Docker using Ruby'"

Runs the built image as an actual container.

docker-compose run javascript -c "console.log('I ran inside of Docker using NodeJS')"

Runs the command against the services defined in the compose file.

✅ Run docker compose ps to check the containers are Up. If the README mentions a port, open http://localhost:PORT in your browser.

3. Gradle (Java/Kotlin)

Medium

Prerequisites

Git Needed to download the project code from GitHub.
JDK (Java) Required to build and run Java/Kotlin projects.
Gradle If the repo includes gradlew (Gradle Wrapper), you don't need to install Gradle separately.

⚠️ This is a large repository, so this method may point to an internal sub-package rather than the actual core product. Check the full README as well.

cd frameworks/gradle

This project's files live in a subfolder, so move into it first.

./gradlew build

Builds the project using Gradle.

✅ A BUILD SUCCESSFUL message means it worked. The output is created under build/.

4. Node.js

Easy

Prerequisites

Git Needed to download the project code from GitHub.
Node.js Node.js must be installed to use npm. The LTS version is recommended.

cd frameworks/solidity/truffle

This project's files live in a subfolder, so move into it first.

npm install

Downloads and installs the libraries listed in package.json.

npm start

Starts the development/run server.

✅ After running the command, open the address shown in the terminal (usually something like http://localhost:3000) in your browser.

5. Rust

Medium

Prerequisites

Git Needed to download the project code from GitHub.
Rust (rustup) Installing via rustup also installs cargo.

⚠️ This is a large repository, so this method may point to an internal sub-package rather than the actual core product. Check the full README as well.

cd frameworks/rust/skeleton

This project's files live in a subfolder, so move into it first.

cargo build --release

Compiles the Rust project.

cargo run

Builds and then immediately runs the program.

✅ If cargo build finishes without errors, it worked. The executable is created under target/.

6. Make

Medium

Prerequisites

Git Needed to download the project code from GitHub.
Make Usually pre-installed on Linux/macOS. On Windows, install separately (e.g. via MSYS2 or WSL).

make jvm

Compiles the code based on the generated build configuration to produce an executable.

✅ If it finishes without errors, it worked. Try running the generated executable directly.
