Technical requirements

For this section, we will have to make use of Vagrant to demonstrate the difference between these methods, as we will require two VMs: one for single-node OpenShift cluster, and the other for the FreeIPA server. Use the following Vagrantfile to spin up an environment:

$ cat Vagrantfile 
$lab_idm = <<SCRIPT
cat <<EOF >> /etc/hosts
172.24.0.11 openshift.example.com openshift
172.24.0.12 idm.example.com idm
EOF
sed -i '/^127.0.0.1.*idm.*$/d' /etc/hosts
yum -y update
yum -y install ipa-server
systemctl restart dbus
ipa-server-install -r IDM.EXAMPLE.COM -n idm.example.com -p idmsecret -a idmsecret --unattended
echo idmsecret | kinit admin
echo supersecret | ipa user-add alice --first Alice --last Springs --password
SCRIPT

$lab_openshift = <<SCRIPT
cat <<EOF >> /etc/hosts
172.24.0.12 idm.example.com idm
EOF
yum -y update
yum install...
