How to get access from client side to container images

[max2020204]

In apphost i add container to builder

var openwebui = builder.AddContainer("openwebui", "ghcr.io/open-webui/open-webui", "latest")
        .WithHttpEndpoint(3000, 3000, openwebui);

var opnweb = openwebui.GetEndpoint("openwebui");

builder.AddProject<Projects.BlazorApp>("frontend")
    .WithReference(opnweb);

In Blazor app, Program cs file, I add this

builder.AddServiceDefaults();

builder.Services.AddHttpClient("openwebui", client =>
{
    client.BaseAddress = new Uri("http+https://openwebui");
});

But every time I tried to access through HttpFactoryClient, i having error address not found
Here i tried to get access to openwebui

@page "/counter"
@rendermode InteractiveServer
@inject IHttpClientFactory HttpClientFactory

<PageTitle>Counter</PageTitle>

<h1>Counter</h1>

<p role="status">Current count: @models</p>

<button class="btn btn-primary" @onclick="IncrementCount">Click me</button>

@code {
    private string models = "";

    private async Task IncrementCount()
    {
        using var http = HttpClientFactory.CreateClient("openwebui");
        var response = await http.GetAsync("api/models");
        models = await response.Content.ReadAsStringAsync();
    }

}

When i try to get access to opnweb, to get Host or Port i having error

System.InvalidOperationException: The endpoint `openwebui` is not allocated for the resource `openwebui`.
   at Aspire.Hosting.ApplicationModel.EndpointReference.get_AllocatedEndpoint() in /_/src/Aspire.Hosting/ApplicationModel/EndpointReference.cs:line …

but in environment variables it shows services__openwebui__openwebui__0

[davidfowl]

Can you show the full stack trace?

If i'm setting port to httpclient, then it's not changing anyting
builder.Services.AddHttpClient("openwebui", client =>
{
client.BaseAddress = new Uri("http+https://openwebui:3000");
});

[davidfowl]

Are you calling AddServiceDefaults? That's how service discovery get wired up to the http client factory.

[max2020204]

Sure.
this code in blazor app
In Blazor app, Program cs file, I add this

builder.AddServiceDefaults();

builder.Services.AddHttpClient("openwebui", client =>
{
    client.BaseAddress = new Uri("http+https://openwebui");
});
