🚀 Docker Task- Custom Nginx Deployment

This project builds and deploys a custom Nginx container using Docker Compose on an AWS EC2 instance. It demonstrates containerization, image customization, volume mounting, and automated provisioning via EC2 user data.

---

🧰 Tech Stack

• AWS EC2 (Ubuntu 22.04)
• Docker
• Docker Compose v2
• Custom Docker Image
• Bind Mount Volume

---

🛠 Setup Instructions

1. Launch EC2 Instance

• Use Ubuntu 22.04 AMI
• Open ports 22 (SSH) and 80 (HTTP) in the security group
• Paste the user data script during launch (see below)

2. EC2 User Data Script

#!/bin/bash set -e apt-get update -y apt-get install -y docker.io curl systemctl enable docker systemctl start docker curl -L "https://github.com/docker/compose/releases/download/v2.24.6/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose chmod +x /usr/local/bin/docker-compose

mkdir -p /home/ubuntu/docker_nginx/html echo "

Hi from Custom Nginx

" > /home/ubuntu/docker_nginx/html/index.html

cat > /home/ubuntu/docker_nginx/Dockerfile <<EOF FROM nginx:latest COPY html/ /usr/share/nginx/html EOF

cat > /home/ubuntu/docker_nginx/docker-compose.yml <<EOF version: '3.8' services: nginx: build: . ports: - "80:80" volumes: - ./html:/usr/share/nginx/html EOF

cd /home/ubuntu/docker_nginx docker-compose up --build -d

✅ Verification Commands docker --version docker compose version docker ps tree /home/ubuntu/docker_nginx cat /home/ubuntu/docker_nginx/html/index.html cat /home/ubuntu/docker_nginx/Dockerfile cat /home/ubuntu/docker_nginx/docker-compose.yml
