Are you tired of juggling multiple terminal commands just to start your full-stack application? This video is your complete guide to mastering Docker Compose to instantly orchestrate a Node.js backend and a PostgreSQL database!

In this step-by-step tutorial, we’ll show you exactly how to define both services in a single docker-compose.yml file. We cover everything you need: from creating a dedicated Dockerfile for your Node.js application, to configuring the internal Docker network so the two containers can communicate, and finally, using volumes to ensure your PostgreSQL data is persistent and safe.

By the end of this CodeOneDigest tutorial, you will be able to start, stop, and tear down your entire Node.js + Postgres development stack with one simple command: docker-compose up -d. This is a must-have skill for modern development and DevOps!

What You Will Learn
• What Docker Compose is and why it's essential for multi-container apps.
• How to write a Dockerfile for your Node.js application.
• The key sections of a docker-compose.yml file (services, build, image, ports, volumes, environment).
• How to configure your Node.js app to correctly connect to the Postgres service by name.
• How to use Docker Volumes to persist your database data.
• The single command to run your entire full-stack application.
