summary
Extends Kubernetes services across clusters by adding minimal CRDs: ServiceExport/ServiceImport CRDs mark and propagate services; controllers create endpoint slices and a VIP or DNS entries. Demos use Submariner (broker, lighthouse, tunnels, overlay for overlapping CIDRs) and GKE (Hub + clusterset) to resolve services via clusterset.local DNS, load‑balance across backends, and expose headless SRV records. Works end‑to‑end (curl shows responses from both clusters, endpoint slices show 2→4 pods) though GKE still lacks full headless SRV/endpoint slice parity.
