VSphere OpenShift - Reusable UPI Tooling

This repo aims at providing tools helping with terraform based UPI of OpenShift/OKD on VSphere.

It is based on ironicbadger/ocp4. You may want to check the writup on openshift.com.

Contrary to its parent, this repo focuses on reusability and primarily targets OKD. We aim at compatibility with Redhat OpenShift, but at the time of writing, we don't have such an environment.

Usage

The main terraform module is at the root of the repository. It covers a single cluster. An example how it may be used can be found in examples/demo.
