title: How to route gRPC in Istio?
body: <p>I'm new with service mesh thing, so I did some PoC of basic implementation of microservices in kubernetes with istio. </p>
  
  <p>I have 2 Deployments which is supposed to be talking to each other using gRPC. When I call the grpc server it returned error <code>rpc error: code = Internal desc = server closed the stream without sending trailers</code></p>
  
  <p>This is my grpc Service config: </p>
  
  <p><code>
  apiVersion: v1
  kind: Service
  metadata:
    name: grpcserver
    labels:
      app: grpcserver
  spec:
    ports:
    - port: 8080
      name: http
    selector:
      app: grpcserver
  </code></p>
