Run GRPC Server

svc := NewDummyService()
lis, err := net.Listen("tcp", viper.GetString("server.binds.grpc"))
if err != nil {
    panic(err)
}
s := grpc.NewServer()
proto.RegisterDummyServer(s, svc)
// Register reflection service on gRPC server.
reflection.Register(s)
if err := s.Serve(lis); err != nil {
    log.Fatalf("grpc: failed to serve: %v", err)
}

Run GRPC HTTP Gateway

ctx := context.Background()
ctx, cancel := context.WithCancel(ctx)
defer cancel()
mux := runtime.NewServeMux()
opts := []grpc.DialOption{grpc.WithInsecure()}
if err := proto.RegisterDummyHandlerFromEndpoint(ctx, mux, viper.GetString("server.binds.grpc"), opts); err != nil {
    log.Fatalf("gw: failed to register: %v", err)
}
log.Fatalf("gw: failed to server: %v", http.ListenAndServe(viper.GetString("server.binds.gw"), mux))
