Feature Overview

Support mapping OpenShift zones to vSphere host groups, in addition to vSphere clusters.

When defining zones for vSphere administrators can map regions to vSphere datacenters and zones to vSphere clusters.

There are use cases where vSphere clusters have only one cluster construct with all their ESXi hosts but the administrators want to divide the ESXi hosts in host groups. A common example is vSphere stretched clusters, where there is only one logical vSphere cluster but the ESXi nodes are distributed across to physical sites, and grouped by site in vSphere host groups.

In order for OpenShift to be able to distribute its nodes on vSphere matching the physical grouping of hosts, OpenShift zones have to be able to map to vSphere host groups too.

Requirements{}

• Users can define OpenShift zones mapping them to host groups at installation time (day 1)
• Users can use host groups as OpenShift zones post-installation (day 2)
