Compose is a tool for defining and running complex applications with Docker. With Compose, you define a multi-container application in a single file, then spin your application up in a single command which does everything that needs to be done to get it running. Using Compose is basically a three-step process:
- Define your app’s environment with a Dockerfile so it can be reproduced anywhere
- Define the services that make up your app in docker-compose.yml so they can be run together in an isolated environment
- Run docker-compose up and Compose will start and run your entire app
