	return options
}

func main() {
	endpoint := resolve.Register("grpc", "hello.grpc.io", []string{"127.0.0.1:8282", "127.0.0.1:8284", "127.0.0.1:8286"})
	roundRobinConn, err := grpc.Dial(endpoint, getDialOptions()...)
	if err != nil {
		panic(err)
	}
	defer roundRobinConn.Close()

	client := serverNameV1.NewGreeterClient(roundRobinConn)
