Current Behavior

ShenYu currently supports Kubernetes Ingress resource for service discovery and routing. However, Ingress is no longer recommended, the Gateway API is the next-generation Kubernetes networking standard, providing more expressive and role-oriented routing capabilities (GatewayClass, Gateway, HTTPRoute, etc.).
