How to extend HyperShift to support a new platform

A Platform represents a series of assumptions and choices that HyperShift makes about the environment where it's running, e.g AWS, IBMCloud, Kubevirt. The implementation of a new platform crosses multiple controllers.

The HostedCluster controller requires an implementation of the Platform interface to shim a particular CAPI implementation and manage required cloud credentials.

The NodePool controller requires an implementation of the machine template reconciliation.

The ControlPlane Operator requires the following:

• Implement cloud credentials

• Reconcile Kubernetes cloud provider config

• Reconcile the OCP Infrastructure CR

• Reconcile secret encryption (if your provider supports KMS)

End to end testing

The end-to-end tests require an implementation of the Cluster interface. As a starting point, check out the None-Platform implementation and its basic test
