How to Install Judge0 CE on Kali Linux Latest

Judge0 CE is an open-source online code execution platform that supports more than 50+ programming languages. In this tutorial, we will guide you on how to install Judge0 CE on Kali Linux Latest.

Prerequisites

  • Kali Linux Latest installed
  • Root privileges
  • Docker installed

Step 1: Install Docker

Before we install Judge0 CE, we need to make sure Docker is installed on our system. To install Docker, run the following command in your terminal:

sudo apt install docker.io

Once done, check the Docker version:

docker --version

Step 2: Clone Judge0 CE repository

Now, let's clone the Judge0 CE repository from GitHub using the following command:

git clone https://github.com/judge0/judge0-ce.git

Once the repository is cloned, move to the cloned directory:

cd judge0-ce

Step 3: Build Judge0 CE image

In this step, we will build Judge0 CE image. To build the image, run the following command:

sudo docker build -t judge0:latest .

This command will take a few minutes to download and install the required dependencies.

Step 4: Start container

Once the image is built, we can start the container by running the following command:

sudo docker run -d --restart always \
-p 80:3000 \
-v /var/run/docker.sock:/var/run/docker.sock \
-e ADMIN_USERNAME=your_admin_username \
-e ADMIN_PASSWORD=your_admin_password \
-e JWT_SECRET=your_jwt_secret \
-e JWT_EXPIRATION=3600 \
-e DATABASE_URL=postgres://postgres:judge0@database:5432/judge0 \
-e RABBITMQ_URL=amqp://guest:guest@rabbitmq:5672/ \
--name judge0 judge0:latest
  • The -d option runs the container in the background.
  • The --restart always option restarts the container automatically if it crashes or the system restarts.
  • The -p 80:3000 option maps the container port 3000 to the host port 80.
  • The -v /var/run/docker.sock:/var/run/docker.sock option mounts the Docker socket from the host to the container. This is necessary for the Judge0 CE API to interact with Docker images.
  • The -e ADMIN_USERNAME=your_admin_username option sets the admin username.
  • The -e ADMIN_PASSWORD=your_admin_password option sets the admin password.
  • The -e JWT_SECRET=your_jwt_secret option sets the JWT secret key.
  • The -e JWT_EXPIRATION=3600 option sets the JWT expiration time in seconds.
  • The -e DATABASE_URL=postgres://postgres:judge0@database:5432/judge0 option sets the PostgreSQL database URL. By default, Judge0 CE uses PostgreSQL as the database.
  • The -e RABBITMQ_URL=amqp://guest:guest@rabbitmq:5672/ option sets the RabbitMQ URL. By default, Judge0 CE uses RabbitMQ as the message broker.
  • The --name judge0 option sets the container name to judge0.
  • The judge0:latest option specifies the image name and tag to use.

Note: Make sure to replace the your_admin_username,your_admin_password and your_jwt_secret values with your own.

Step 5: Test Judge0 CE installation

To test if Judge0 CE is installed correctly, open your web browser and go to http://localhost or http://your_server_ip. You should see the Judge0 CE API documentation page.
