Introduction to Docker Compose

source: docker
  • 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 starts and runs your entire app. source : https://docs.docker.com/compose/
