+## Objective:
+Pulling content from Github & exposing through container
+
+## Instructions:
+1. Create EC2 instance & enable required ports (eg. 22, 80, 8080) in the security group
+2. Install Docker
+   * *(https://github.com/pandacloud1/DEVOPS/tree/main/Installation_Scripts/Docker)*
+3. Create Dockerfile as below: 
+   * Install Git, Apache
+   * Pull content from Github
+   * Copy the content to /var/www/html/ location
+   * Start Apache service 
+4. Create Docker image from 'Dockerfile'
+5. Create Container from Docker image exposing required port of the container with the local machine
+6. Access the content from the browser using <ec2_public_IP>
+
