grpc .net core in docker Call Method failed Grpc.Core.RpcException: 'Status(StatusCode=Unavailable, Detail="Endpoint read failed")'

[RavenZZ]

I use the simplest Greeter Project , and then switch them into .net core1.1 project

Here is the Server Code
```C#
class GreeterImpl : Greeter.GreeterBase
{
// Server side handler of the SayHello RPC
public override Task SayHello(HelloRequest request, ServerCallContext context)
{
return Task.FromResult(new HelloReply { Message = "Hello " + request.Name });
}
}
class Program
{
const int Port = 50051;

public static void Main(string[] args)
{
  Server server = new Server
  {
    Services = { Greeter.BindService(new GreeterImpl()) },
    Ports = { new ServerPort("localhost", Port, ServerCredentials.Insecure) }
  };
  server.Start();


  server.ShutdownTask.Wait();
}

}

Here is the Dockerfile
```docker
FROM microsoft/aspnetcore:1.1
ARG source
WORKDIR /app

COPY ${source:-obj/Docker/publish} .
ENTRYPOINT ["dotnet", "GreeterServer2.dll"]

Here is the build and run bash, they are success.

docker build -t ravenzz/hello .
docker run -p 50051:50051 ravenzz/hello:latest

But when I call it
I got the exception "Status(StatusCode=Unavailable, Detail="Endpoint read failed")"

Any help is appreciated

Solved. I should listen on 0.0.0.0 not localhost
