Clone the template following the procedure described here [[Linux_Virtualization_Cloning_a_KVM_Guest_Virtual_Machine|Cloning a KVM Guest]]. While cloning, consider the following:
* The access host needs two interfaces, one external and one internal. For details see [[Linux_Virtualization_Cloning_a_KVM_Guest_Virtual_Machine#Network|Cloning a KVM Guest - Networking]] and [[KVM Virtualization Attaching a Guest Directly to a Virtualization Host Network Interface|Attaching a Guest Directly to a Virtualization Host Network Interface]].
* The access host needs only one storage device.
====Post-Cloning====
* Turn off external root access.
* Add external users.
* Disable and remove Docker.
{{Warn|There is no need to install HAProxy manually to serve as master node load balancer, the OpenShift installation procedure will do it.}}
* Add the IP addresses for masters, support and lb (itself) to /etc/hosts, the DNS server may not be operational when we need it.

Internal

Clone the Basic Template

Use the basic template as a base image and clone it, as described below.


While cloning the guest, make sure to provision a directly-mapped network interface.

Cloning a Guest

The process will produce a ocp36.ingress.

External Access Configuration

Create external accounts to be exposed publicly and configure their ssh access (~/.ssh/authorized_keys).








Access/Proxy Host Configuration

Clone the Template

Clone the template following the procedure described here Cloning a KVM Guest. While cloning, consider the following:

Post-Cloning

  • Turn off external root access.
  • Add external users.
  • Disable and remove Docker.

There is no need to install HAProxy manually to serve as master node load balancer, the OpenShift installation procedure will do it.

  • Add the IP addresses for masters, support and lb (itself) to /etc/hosts, the DNS server may not be operational when we need it.
