Goal

Add vSphere zonal support in Hive, so that ACM can expose vSphere zonal capabilities to end-users.

Feature

As an Infrastructure Administrator, I want to deploy OpenShift on vSphere with supervisor (aka Masters) and worker nodes (from a MachineSet) across multiple vSphere data centers and multiple vSphere clusters using full stack automation (IPI) and user provided infrastructure (UPI).

See OCPSTRAT-153 for additional details.

(Note: This is tech debt for a feature that was implemented in OCP 4.13.)

Out of scope

• There are no support the conversion of a non-zonal configuration (i.e. an existing OpenShift installation without 1+ zones) to a zonal configuration (1+ zones), but zonal UPI installation by the Infrastructure Administrator is permitted.

Scenarios for consideration:

• OpenShift in vSphere across different zones to avoid single points of failure, whereby each node is in different ESX clusters within the same vSphere datacenter, but in different networks.
• OpenShift in vSphere across multiple vSphere datacenter, while ensuring workers and masters are spread across 2 different datacenter in different subnets. (RFE-845, RFE-459).

Success Criteria

• Ensure OpenShift in vSphere can be deployed across the 3 zones (vSphere clusters) within the same vCenter [like we do with AWS, GCP & Azure].
• Ensure this capability is documented and tested.
