OpenShift Enhancement
Inspired by the Kubernetes community enhancement process, OpenShift also uses enhancements to drive and define its features. Early in the process of adding a new infrastructure provider to OpenShift, an enhancement document should be created to scope the work that is being done and to expose design details which might need modification on OpenShift.
To begin, visit the OpenShift enhancements repository and become familiar with the enhancement template as well as the enhancement guidelines. When ready, create a pull request with your new infrastructure provider enhancement to the repository. To aid in this process, here are two examples of pull requests for recently added platforms:
Writing the enhancement
The enhancement template should guide you in organizing the text of your enhancement. But, it has been designed primarily for feature and code changes to OpenShift, so there are a few topics you should consider specifically while writing.
What will an OpenShift cluster look like on the new infrastructure provider? (Adding a topology diagram can be very helpful to explain the logical architecture.)
Are there special networking considerations that need to be explained (e.g. DNS and load balancing strategies)?
What types of compute and storage are available on the infrastructure?
How will users install and consume OpenShift on the infrastructure?
The "Drawbacks" and "Alternatives" sections in the enhancement do not always make sense for new infrastructure providers. Depending on the options available for deploying OpenShift on the infrastructure, the "Alternatives" section can be a good place to talk about other methods of deployment.
