Feature Overview

As an Infrastructure Administrator, I want to deploy OpenShift on Nutanix distributing the control plane and compute nodes across multiple regions and zones, forming different failure domains.

As an Infrastructure Administrator, I want to configure an existing OpenShift cluster to distribute the nodes across regions and zones, forming different failure domains.

Goals

Install OpenShift on Nutanix using IPI / UPI in multiple regions and zones.

Requirements (aka. Acceptance Criteria):

• Ensure Nutanix IPI can successfully be deployed with ODF across multiple zones (like we do with vSphere, AWS, GCP & Azure)
• Ensure zonal configuration in Nutanix using UPI is documented and tested

vSphere Implementation

This implementation would follow the same idea that has been done for vSphere. The following are the main PRs for vSphere:
