# Akka.NET Management and Service Discovery

## When to Use This Skill

Use this skill when:
- Deploying Akka.NET clusters to Kubernetes or cloud environments
- Replacing static seed nodes with dynamic service discovery
- Configuring cluster bootstrap for auto-formation
- Setting up health endpoints for load balancers
- Integrating with Azure Table Storage, Kubernetes API, or config-based discovery

## Reference Files

- [discovery-providers.md](discovery-providers.md): Config, Kubernetes, and Azure discovery setup with full code and deployment YAML
- [configuration-reference.md](configuration-reference.md): Strongly-typed configuration model classes

## Overview

**Akka.Management** provides HTTP endpoints for cluster management and integrates with **Akka.Cluster.Bootstrap** to enable dynamic cluster formation using service discovery instead of static seed nodes.

### Why Use Akka.Management?

| Approach | Pros | Cons |
|----------|------|------|
| Static Seed Nodes | Simple, no dependencies | Doesn't scale, requires known IPs |
| Akka.Management | Dynamic discovery, scales to N nodes | More configuration, external dependencies |

**Use static seed nodes** for: Development, single-node deployments, fixed infrastructure.

**Use Akka.Management** for: Kubernetes, auto-scaling groups, dynamic environments, production clusters.

## Akka.Hosting Configuration

### Basic Setup with Mode Selection

```csharp
public static class AkkaConfiguration
{
    public static IServiceCollection ConfigureAkka(
        this IServiceCollection services,
        Action<AkkaConfigurationBuilder, IServiceProvider>? additionalConfig = null)
    {
        services.AddOptions<AkkaSettings>()
            .BindConfiguration("AkkaSettings")
            .ValidateDataAnnotations()
            .ValidateOnStart();

        return services.AddAkka("MySystem", (builder, sp) =>
        {
            var settings = sp.GetRequiredService<IOptions<AkkaSettings>>().Value;
            var configuration = sp.GetRequiredService<IConfiguration>();

            ConfigureNetwork(builder, settings, configuration);
            ConfigureHealthChecks(builder);

            additionalConfig?.Invoke(builder, sp);
        });
    }

    private static void ConfigureNetwork(
        AkkaConfigurationBuilder builder,
        AkkaSettings settings,
        IConfiguration configuration)
    {
        if (settings.ExecutionMode == AkkaExecutionMode.LocalTest)
            return;

        builder.WithRemoting(settings.RemoteOptions);

        if (settings.ClusterBootstrapOptions.Enabled)
            ConfigureAkkaManagement(builder, settings, configuration);
        else
            builder.WithClustering(settings.ClusterOptions);
    }
}
```

### Akka.Management Configuration

```csharp
private static void ConfigureAkkaManagement(
    AkkaConfigurationBuilder builder,
    AkkaSettings settings,
    IConfiguration configuration)
{
    var mgmtOptions = settings.AkkaManagementOptions;
    var bootstrapOptions = settings.ClusterBootstrapOptions;

    // IMPORTANT: Clear seed nodes when using Akka.Management
    settings.ClusterOptions.SeedNodes = [];

    builder
        .WithClustering(settings.ClusterOptions)
        .WithAkkaManagement(setup =>
        {
            setup.Http.HostName = mgmtOptions.HostName;
            setup.Http.Port = mgmtOptions.Port;
            setup.Http.BindHostName = "0.0.0.0";
            setup.Http.BindPort = mgmtOptions.Port;
        })
        .WithClusterBootstrap(options =>
        {
            options.ContactPointDiscovery.ServiceName = bootstrapOptions.ServiceName;
            options.ContactPointDiscovery.PortName = bootstrapOptions.PortName;
            options.ContactPointDiscovery.RequiredContactPointsNr = bootstrapOptions.RequiredContactPointsNr;
