Docker Compose : Why need it ?

Introduction

If you are using docker everywhere then , to get a typical docker application up and running you will need to run a lot of docker commands in correct order each time … just to start an environment  , which can be tedious.

Instead wouldn't it be easier to just run one command and get your environment up.

Common Use case launch a dev or test environment

For Example : If you want to install Hygieia , you can use just once command as described here http://www.capitalone.io/Hygieia/builddocker.html
