Ubuntu and Judge0 on Windows: Developer Guide

Prerequisites ⚙️

Before we dive into the installation steps, I request you to install warp terminal => link Trust me, you’ll thank me later.

🔧 Why install Warp?
With Warp, you can debug your errors directly inside the terminal, improving your development workflow!

1. Installing Ubuntu on Windows with WSL 🐧💻

To begin, you’ll need to install Ubuntu on your Windows machine using Windows Subsystem for Linux (WSL).

Enable WSL
- Open PowerShell as Administrator and run
- Run this command
```
  wsl --install
```
  - This command will install WSL along with the default Ubuntu distribution.
  - After installation, restart your system to complete the setup.
Set Up Ubuntu
- Open the Ubuntu terminal from the Start menu and follow the prompts to create a UNIX username and password.
Update Ubuntu
- Once Ubuntu is set up. update all the installed packages by running the following commands :
```
  sudo apt update
```
- upgrade the installed packages:
```
  sudo apt upgrade -y
```

Now, You’re all set to start working on Ubuntu within Windows! 🎉

Now that Ubuntu is up and running, let’s move on to installing Docker and Docker Compose to manage containers efficiently.

2. Installing Docker and Docker Compose 🐳📦

Make sure you are in the ubantu terminal

Install Docker
- After updating, run this command to install Docker:
```
  sudo apt install -y docker.io
```
Install Docker Compose

```
  sudo apt install -y docker-compose
```

Docker and Docker Compose are now ready for use on your Ubuntu environment! 🎉

3. Installing Judge0 on Your Local Server ⚙️💡

Let’s install Judge0, a powerful online code execution API, on your local machine. Follow these steps carefully.

Download Judge0

First, run the following command to download the Judge0 release archive:

  wget https://github.com/judge0/judge0/releases/download/v1.13.1/judge0-v1.13.1.zip

Extract Judge0
- After the download is complete, run the following command to unzip the archive:
```
  unzip judge0-v1.13.1.zip
```

NOTE => you will get an error here, so firstly you have to install unzip in your terminal. In such situations, warp terminal makes your life easy

Set Up Secure Passwords
- Visit random.org password generator and copy two random passwords.
- Open the .env configuration file by running:
```
  nano judge0-v1.13.1/.env
```
- Update password with the generated passwords, you will find these fields when you scroll down
  - REDIS_PASSWORD
  - POSTGRES_PASSWORD
- Save the file and exit => follow the instruction on there
Start Judge0 Services
- Navigate to the Judge0 folder where you downloaded and extracted the files:
```
  cd judge0-v1.13.1
```
- Now all the things will take place in this directory itself
- Start the database and Redis services by running:
```
  docker-compose up -d db redis
```
- Wait for a few seconds:
```
  sleep 10s
```
- start the remaining services:
```
  docker-compose up -d
```
- Wait for a few more seconds:
```
  sleep 5s
```

Judge0 should now be up and running on your local server! 🎯

4. Verifying the Installation ✅🔍

To make sure everything is set up correctly, follow these steps:

Check Judge0 API Docs
- Open your browser and go to:
```
  http://localhost:2358/docs
```

- If you go to dummy client then a dummy client will appear, you can play in here

Make sure the server is running when you are using this, How to make sure this works
- simple in the warp terminal , ask to check for judge0 server running in your system

sudo docker ps | grep judge0
