Getting started with Aspire & Aspirate: No Dockerfile components selected.

[cataggar]

I'm just getting started with Aspire & Aspirate. I attempted to use the dotnet new aspire-starter template and then modify the AppHost/Program.cs to add a Docker container.

var builder = DistributedApplication.CreateBuilder(args);

var api = builder
    .AddProject<Projects.Aspir8_ApiService>("api");

builder.AddContainer("apiContainer", "mcr.microsoft.com/dotnet/aspnet:5.0")
    .WithDockerfile(".")
    .WithReference(api);

builder.Build().Run();

But when I run aspirate build, I get the error No Dockerfile components selected. Skipping build and publish action..

I put everything in a GitHub repo to reproduce at https://github.com/cataggar/aspire-starter .

cd Aspir8.AppHost
aspire init
az acr login -n cataggar26acr
aspirate build --disable-secrets=true

Example output:

~/ms/aspire-starter/Aspir8.AppHost> az acr login -n cataggar26acr
Login Succeeded
~/ms/aspire-starter/Aspir8.AppHost> aspirate build --disable-secrets=true
