What is Docker Compose?

Welcome! So far, you've learned to run individual containers. But what if your application needs more than one?

This quickly gets complicated! How do they talk to each other? How do you start them all in the correct order?

Manually managing multiple containers and their connections can be tedious and error-prone.
