How To Install docker-compose on CentOS 7
Introduction

What is docker-compose
Compose is a tool for defining and running multi-container Docker applications. With Compose, you use a Compose file to configure your application’s services. Then, using a single command, you create and start all the services from your configuration. Compose is great for development, testing, and staging environments, as well as CI workflows. Using Compose is basically a three-step process. 1. Define your app’s environment with a Dockerfile so it can be reproduced anywhere. 2. Define the services that make up your app in docker-compose.yml so they can be run together in an isolated environment 3. Lastly, run docker-compose up and Compose will start and run your entire app.
