Vagrant Virtualbox setup for Docker EE Engine on CentOS 7.3
========================
An exercise on installing Docker EE Engine and properly configuring Device Mapper on CentOS, which may be helpful for walking through the install and configuration of Docker EE Engine before actually doing so in production environments. This vagrant file is provided strictly for educational purposes.
## Download vagrant from Vagrant website
```
https://www.vagrantup.com/downloads.html
```
## Install Virtual Box
```
https://www.virtualbox.org/wiki/Downloads
```
## Download CentOS 7 box
```
vagrant init centos/7
```
## Create files in project to store environment variables with custom values for use by Vagrant
```
ee_url
```
## Bring up nodes
```
vagrant up centos-node
```
### Validate Docker Device Mapper Config
The install script that is run from provisioning the node will automatically install Docker EE and configure devicemapper for you.
```
[vagrant@centos-node ~]$ docker info
