INSECURE

Calling gRPC from inside docker-compose or kubernetes is all over http, so the following needs to be set for those calls to succeed.

// This switch must be set before creating the GrpcChannel/HttpClient.
AppContext.SetSwitch("System.Net.Http.SocketsHttpHandler.Http2UnencryptedSupport", true);

Call insecure gRPC services with .NET Core client Additional configuration is required to call insecure gRPC services with the .NET Core client. The gRPC client must set the System.Net.Http.SocketsHttpHandler.Http2UnencryptedSupport switch to true and use http in the server address:

// This switch must be set before creating the GrpcChannel/HttpClient.
AppContext.SetSwitch("System.Net.Http.SocketsHttpHandler.Http2UnencryptedSupport", true);

// The port number(5000) must match the port of the gRPC server.
var channel = GrpcChannel.ForAddress("http://localhost:5000");
var client = new Greet.GreeterClient(channel);
