# docker-compose.prod.yml — defines and manages multiple production containers

services:  # Define three services — backend, frontend, and nginx

  backend:  # Backend service — our Flask API
    image: hackitect7/flask-api:latest  # Use Docker Hub image built from the backend folder
    ports:
      - "5000:5000"  # Expose container port 5000 to the host for external API access

  frontend:  # Frontend service — Node.js application
    image: hackitect7/node-frontend:latest  # Use Docker Hub image built from the frontend folder
    ports:
      - "3000:3000"  # Expose container port 3000 to the host to access frontend directly

  nginx:  # Nginx service — reverse proxy
    image: nginx:latest  # Use official nginx image (can be replaced with a custom image if needed)
    volumes:
      - ./nginx/nginx.conf:/etc/nginx/nginx.conf  # Mount local nginx config into container to control routing behavior
    ports:
      - "80:80"  # Open port 80 on host for incoming HTTP requests
    depends_on:  # Ensure nginx starts after backend and frontend are running
