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
$common_provision = <<SCRIPT
cat <<EOF >> /etc/hosts
172.24.0.11 openshift-master.example.com openshift-master
172.24.0.12 openshift-node-1.example.com openshift-node-1
172.24.0.13 openshift-node-2.example.com openshift-node-2
EOF
sed -i '/^127.0.0.1.*openshift.*$/d' /etc/hosts
yum -y update
yum install -y docker
systemctl start docker
systemctl enable...
