Installing Docker on Windows & Making GitHub.io Live

This project documents the complete setup process for:

It serves as a beginner-friendly guide to containerization and basic web deployment.

Part 1: Installing Docker on Windows

Docker allows applications to run inside lightweight, portable containers.

Step 1: Install Docker Desktop for Windows

  1. Visit the official Docker website:
    https://www.docker.com/products/docker-desktop

  2. Download Docker Desktop for Windows

  3. Run the installer (Docker Desktop Installer.exe)

  4. During installation:

    • Enable WSL 2 if prompted
    • Keep default settings

  5. Restart your system if required

  6. Open Docker Desktop from the Start Menu

  7. Wait until it shows Docker is running

Step 2: Verify Docker Installation

Open Command Prompt or PowerShell and run:

docker --version

Then run a test container:

docker run hello-world

If Docker is installed correctly, a confirmation message will be displayed.

Step 3: Run an Ubuntu Container

docker run -it ubuntu:22.04 bash

This starts an interactive Ubuntu terminal inside a Docker container where you can execute Linux commands.

Step 4: Install Java Inside the Container (Example)

Inside the Ubuntu container:

apt update
apt install default-jdk -y
java -version

Create a Java file:

nano Hello.java

Add the following code:

class Hello {
    public static void main(String[] args) {
        System.out.println("Hello from Docker on Windows!");
    }
}

Compile and run:

javac Hello.java
java Hello

Expected output:

Hello from Docker on Windows!

Part 2: Hosting a Website with GitHub Pages

GitHub Pages allows you to host static websites directly from a GitHub repository.

Step 1: Create a Repository

  1. Go to https://github.com\
  2. Click New Repository
  3. Name the repository exactly:
<!-- -->

yourusername.github.io

Replace yourusername with your actual GitHub username.

The repository name must match your GitHub username exactly for the site to work.

Step 2: Add Website Files

Upload your website files such as:

Or push your project using Git from your local machine:

git init
git add .
git commit -m "Initial website"
git branch -M main
git remote add origin https://github.com/yourusername/yourusername.github.io.git
git push -u origin main

Step 3: Enable GitHub Pages

  1. Open your repository on GitHub\
  2. Click on Settings\
  3. Click Pages from the left sidebar\
  4. Under Branch, select:
<!-- -->

Branch: main
Folder: /root
  1. Click Save

Step 4: Access the Live Website

After a few minutes, your website will be live at:

https://yourusername.github.io

If the site does not appear immediately, wait a few minutes and refresh the page.
