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:
- Adjust the memory and the number of virtual CPUs.
- Provision a directly-mapped network interface.
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:
- The access host needs two interfaces, one external and one internal. For details see Cloning a KVM Guest - Networking and 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.
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.
