Docker Compose in 6 minutes! Mongo, Express, React, Node (MERN) Application Tutorial

If you are using Docker and your application consists of multiple services, you need to be using docker-compose!

In this video, I walk through a full example of how to configure docker-compose for a MERN (Mongo, Express, React, and Node.js) application explaining each configuration option along the way.

The application shown is based on this post:   / how-to-create-your-first-mern-mongodb-expr...

Cheers!
