Hi, I'm having issue running the microservice template with blazor server ui running inside kubernetes. I was able to have all services and auth-server running fine inside kubernetes. Blazor Server UI runs fine if spec.replicas = 1; however, if I have Blazor Server spec.replicas > 1, I'd get a websocket connection failed from the browser. I've tried the following but none successful:
Environments:
- Google GKE Kubernetes
- Nginx Ingress Controller
- Microservice Template v4.4.3
BlazorModule.cs
public override void PreConfigureServices(ServiceConfigurationContext context)
{
...
context.Services.PreConfigure<ISignalRServerBuilder>(builder =>
{
builder.AddStackExchangeRedis(configuration["Redis:Configuration"], options =>
{
options.Configuration.ChannelPrefix = "Blazor-Channel";
});
});
}
public override void ConfigureServices(ServiceConfigurationContext context)
{
...
context.Services.Configure<ForwardedHeadersOptions>(options =>
{
options.ForwardedHeaders =
ForwardedHeaders.XForwardedFor | ForwardedHeaders.XForwardedProto;
});
}
public override void OnApplicationInitialization(ApplicationInitializationContext context)
{
...
app.UseCookiePolicy(); // added this, Before UseAuthentication or anything else that writes cookies.
app.UseForwardedHeaders();
}
Ingress.yml

Hello, We don't have experience on kubernetes deployment of Blazor.Server application yet.
Can you successfully deploy with replicas a new microsoft default blazor.server application so that we can verify it is about abp template?
Furthermore, Is there any console logs on server when try to increase replicas?
