USER STORY:

• As a partner I would like to be able to run OPCT on OCP Compact Topology, so I can certify this topology in my catalog.

VCSP Partner Program:

"Supported topologies: highly-available with 3 control-plane nodes and at least 2 worker nodes, compact with 3 nodes, or single-node"

DESCRIPTION:

Feature to evaluate running on Compact:
