A Kubernetes controller to automatically expose a statefulset through GCP Private Service Connect, using Port Mapping NEGs.
See the design doc for more info.
This is a WIP, currently undergoing testing and lots of changes. Contributions are very much welcome.
psc-portmapper requires its target statefulset to keep a 1:1 pod-node relationship, to be able to map a single port (i.e. on the forwarding rule exposed through the service attachment) to a single pod. This is because it creates a NodePort service to satisfy the port-mapping Network Endpoint Group's requirement to have an instance:port pair as its target.
Because of this, psc-portmapper isn't compatible with Autopilot clusters, as they don't create actual instances which can be used as endpoint targets.
See the Chart docs.
