you want the latest version of Docker (see

1.3 Installing Docker on CentOS 7
Problem
You want to use Docker on CentOS 7.
Solution
Install the Docker package by using the 
yum
package manager. CentOS uses 
systemd
,
so to manage the 
docker
service, you can use the 
systemctl
command:
$ sudo yum update
$ sudo yum -y install docker
$ sudo systemctl start docker
You can also use the official Docker installation script, which will use packages from
the Docker repository:
$ sudo yum update
$ sudo curl -sSL https://get.docker.com/ | sh
1.4 Setting Up a Local Docker Host by Using Vagrant
Problem
The operating system of your local machine is different from the operating system
you want to use Docker on. For example, you are running OS X and want to try
Docker on Ubuntu.
Solution
Use 
Vagrant
 to start a virtual machine (VM) locally and bootstrap the VM by using a
shell provisioner in the Vagrantfile.
