Summary

Aspire 13.1 introduced ContainerRegistryResource for general-purpose container registries beyond Azure Container Registry. Only documented in what's-new.

What's Missing

Core API

var builder = DistributedApplication.CreateBuilder(args);

// Add a generic container registry
var registry = builder.AddContainerRegistry("myregistry", "registry.example.com");

var api = builder.AddProject<Projects.Api>("api")
    .WithContainerRegistry(registry);

Pipeline Integration

$ aspire do push
# Builds images and pushes to configured registry

Azure Container Apps Explicit Registry

// Explicit ACR configuration (13.1)
var acr = builder.AddAzureContainerAppEnvironment("myenv");

var api = builder.AddProject<Projects.Api>("api")
    .WithContainerRegistry(acr);

Suggested Content

1. Generic container registries - DockerHub, Harbor, etc.
2. Azure Container Registry - explicit vs implicit provisioning
3. aspire do push - pipeline step for image pushing
4. Authentication - registry credentials configuration
5. Examples - DockerHub, private registry, ACR

Why It Matters

Container registry configuration was implicit before. Users need to understand the new explicit model.
