Prepare a host for OpenShift 4 Provisioning
The intent of these instructions is to install RHEL on decently sized bare metal so that it can perform as a KVM host.
OpenShift 4 has significant requirements for individual nodes, so these instructions make it possible to install VMs to meet the needs of the installer.
For the purposes of these ansible playbook, RHEL8 is obtained and provisioned on the bare metal host.
After completing the insall, add to the sudoers list for the convience of future commands.
To add to sudoers list:
su
usermod -aG wheel <username>
su <username>
Then enable sshd so that ansible can access the host.
sudo systemctl start sshd.service
sudo systemctl enable sshd.service
