Overview
In this tutorial I will show how to Setup Docker CE for CentOS 7.
The default Docker version that comes with CentOS is very old and only supports docker-compose syntax version 2. To use a higher level of docker-compose syntax we need the latest Docker CE.
This tutorial is the short version of the official Docker CE tutorial.
