OpenShift 3.6 Ingress Guest Configuration

Internal

• OpenShift 3.6 Installation

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.

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:

• 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.
