Connect to Orleans cluster in Azure Container Apps

[SoucianceEqdamRashti]

Hello,

I have an Orleans cluster setup with this Silo config in an ASP.NET Core app. It is deployed to an azure container app.

silo.AddAzureTableGrainStorage(
                name: "apppersistence",
                configureOptions: options =>
                {
                    options.ConfigureTableServiceClient("DefaultEndpointsProtocol==");
                    options.DeleteStateOnClear = true;
                });
        silo.Configure<SiloOptions>(options =>
        {
            options.SiloName = "OrleansContainerAppSilo";

        })
        .ConfigureEndpoints(siloPort: 11_111, gatewayPort: 30_000, listenOnAnyHostAddress: true)
        .UseAzureStorageClustering(options => options.ConfigureTableServiceClient("="));
        silo.Configure<ClusterOptions>(options =>
        {
            options.ClusterId = "OrleansClusterAppDev";
            options.ServiceId = "Automation Center Orleans App";
        });

If I call the web api controller that exist inside the container which calls a grain, then that works fine since orleans and the asp.net core app reside on the same host.

Now if I have a completely separate asp.net core app residing locally on my machine and I want to connect to the orleans cluster in the container app. Here is the client setup:

 using IHost host = Host.CreateDefaultBuilder(args)
         .UseOrleansClient((context, client) =>
         {
             client.Configure<ClusterOptions>(options =>
             {
                 options.ClusterId = "OrleansClusterAppDev";
                 options.ServiceId = "Automation Center Orleans App";
             })
             .UseAzureStorageClustering(
                 options =>
                 options.ConfigureTableServiceClient(
                     "DefaultEndpointsProtocol=https;AccountName=="));
         })
         .UseConsoleLifetime()
         .Build();

    await host.StartAsync();

    IGrainFactory client = host.Services.GetRequiredService<IGrainFactory>();

If I now run the local app, I now get this error:

{"Unable to connect to any of the 1 available gateways."}
{System.Collections.ListDictionaryInternal}

Is there something missing in the client or server side?

If the asp.net core app you are running locally was running as a container app in the same container app environment that would work. But the endpoint S100.100.0.13:30000 is not exposed outside your container app/environment so you cannot connect from you local machine to an Orleans cluster running in Azure Container Apps.

Container apps does support exposing TCP as far as I know, have not tried it. But it would be without any security or authentication so that is a BAD idea - I'm not sure how you would approach it if you needed to.

Best approach would be to also deploy your "client" app to the same aca environment.
