4. Dockerize a Node.js App with a Database (PostgreSQL/MySQL)

Objective: Containerize a Node.js app with a database service.
Steps:

Set up a Node.js app with API endpoints.
Containerize the app by creating a Dockerfile.
Use docker-compose to spin up a PostgreSQL or MySQL container and link it to your Node.js app.
Add data persistence for your database using Docker volumes.
Expose relevant ports to interact with the app from the host machine.

What you'll practice:

Dockerizing a full-stack application.
Managing different services (API and database).
Using Docker volumes to persist data across container restarts.
