GRPCRoute
also: GRPCRoute (Gateway API)
GRPCRoute is a Kubernetes resource that defines routing rules for gRPC traffic, typically used with service mesh implementations like Istio or Envoy to control how gRPC requests are handled and distributed across backend services.
GRPCRoute is a Kubernetes Gateway API resource that specifies how gRPC traffic should be routed within a cluster. It allows you to define rules for matching gRPC requests based on hostnames, paths, methods, and headers, then direct that traffic to specific backend services.
GRPCRoute works alongside a Gateway resource to manage ingress and internal gRPC traffic. For example, you might use GRPCRoute to route all requests to api.example.com/user.UserService to a specific backend service, while routing api.example.com/order.OrderService to another service.
Unlike HTTP routing, GRPCRoute is optimized for gRPC's binary protocol and understands gRPC-specific semantics. It integrates with Kubernetes service meshes and load balancers that support the Gateway API standard.
