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.
- Provision just one storage device - the guest image device.
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).
- Turn off external root access.
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.
