This project demonstrates a simple load balancer setup using Nginx and multiple Node.js backend servers, orchestrated with Docker Compose.

• nginx.conf: Nginx configuration for load balancing
• docker-compose.yaml: Defines Nginx and three Node.js app services
• server.js: Node.js Express server
• index.html: Frontend page
• images/: Static images

1. Build and start the services:

   docker-compose up --build
   

2. Access the load balancer at http://localhost:8080
3. Each request is distributed to one of the backend Node.js apps.

• If you see 502 Bad Gateway, ensure your Nginx config points to app1:3000, app2:3000, app3:3000.
• Check container logs for errors:

  docker logs <container_name>
