You are tasked with creating a production-ready Docker solution for a multi-service web application. The application consists of: Node.js backend API, React.js frontend, PostgreSQL database .The requirements are as follows:
a) Use multi-stage builds to optimize the Docker image size for both the backend and frontend.
b) The frontend should be served through an NGINX web server inside a container.
c) The Node.js API should use environment variables (for database connection, API keys, etc.) that can be changed without modifying the Docker image.
d) Use Docker's networking to allow the backend, frontend, and database to communicate with each other without exposing internal services to the host.
e) Ensure that PostgreSQL data persists across container restarts.
f) Create a Docker Compose setup to orchestrate the multi-container environment
For the above:
1. Write the Dockerfile for both the backend (Node.js) and frontend (React.js) using multi-stage builds.
2. Write the Docker Compose file to orchestrate the services (backend, frontend, PostgreSQL, and NGINX).
3. Ensure that the setup allows developers to run the system in development mode (with live reloading for the frontend and backend) and in production mode (with optimized images and no live reloading).
4. Explain how you would handle logging and monitoring for these containers in production
