Architecture
Ingress/Gateway API/CRDs → higress-controller (Go) → Istio Pilot → xDS (LDS/RDS/CDS/EDS) → higress-gateway (Envoy + Wasm)
- Control plane: higress-controller (Go) watches K8s resources, converts to Istio config, pushes via xDS
- Data plane: higress-gateway (Envoy-based) handles all traffic, runs Wasm plugins, zero-downtime config reload
- Three ingress interfaces: Standard K8s Ingress, Gateway API, Istio API (all simultaneous)
