For this chapter, we will be using the following configuration of VMs managed via Vagrant using the default VirtualBox provider:

Name	Role
openshift-master	Master
openshift-node-1	Node
openshift-node-2	Node

Make sure you have enough RAM on your desktop or laptop you use. The configuration above was tested with 8 GB RAM, but it was barely enough, so we recommend running it on a system with 16 GB at least.

This configuration corresponds to the following Vagrantfile:

$ cat Vagrantfile $common_provision = <<SCRIPTcat <<EOF >> /etc/hosts172.24.0.11 openshift-master.example.com openshift-master172.24.0.12 openshift-node-1.example.com openshift-node-1172.24.0.13 openshift-node-2.example.com openshift-node-2EOF ...
