The project emphasizes practical skills in containerization, networking, and data persistence. Key Highlights & Implementation Steps: System Architecture (3:12 - 5:35): The application consists of a Frontend (Nginx), Backend (Node.js), and Database (MongoDB). The architecture uses lightweight Alpine images for efficiency. Environment Setup (6:13 - 10:10): The host uses an AWS EC2 Ubuntu instance where Docker and Docker Compose are installed and verified. Frontend Containerization (13:15 - 16:15): A custom Dockerfile.frontend is created to serve static assets via Nginx on port 80. Backend Containerization (18:24 - 22:15): A Dockerfile.backend is built to manage the Node.js environment, installing dependencies and running the app on port 5001. Orchestration with Docker Compose (23:36 - 35:20): A docker-compose.yml file is created to define the multi-container setup, including networking, volume mounting for MongoDB data persistence, and service dependencies (e.g., ensuring the DB starts before the Backend). Testing and Validation (37:15 - 39:15): The application is successfully deployed and tested by creating users, placing orders, and verifying that data persists even after taking the containers down using volumes. This project serves as a comprehensive guide for beginners to understand how to bridge the gap between theory and real-world application deployment using Docker. 🎥 Watch all Docker episodes here : https://www.youtube.com/playlist?list=PLBr8obKbpkYv7jxBr2Dka3t2zXLiBRymh 🎥 Watch all trivy episodes here : https://www.youtube.com/playlist?list=PLBr8obKbpkYsGrdKwFXqRTYcvv1KELCLn 🎥 Watch all Jenkins episodes here: https://www.youtube.com/playlist?list=PLBr8obKbpkYuGg5JDHaL26_DiHC9hdQJv For all updates: Let's Connect on LinkedIn: https://www.linkedin.com/in/theshubhamgour Follow me instagram: https://www.instagram.com/theshubhamgour Follow me Twitter: https://www.twitter.com/theshubhamgour
