如何在Azure辅助角色（AKKA.NET）中配置远程参与者配置

Question

我一直在努力研究过去两天，试图找出如何将基本控制台应用程序部署到Azure辅助角色并使其具备可以从某种基于客户端的应用程序远程访问，例如MVC网络应用程序。下面的答案

Answer 1

我开始让我的Actor状态包含在我的MVC应用程序与之通信的本地控制台应用程序中。我希望将自己的应用程序部署到Azure生态系统中，并且认为将状态维持在工作者角色之内，并在应用程序服务中托管一个思维“客户端”MVC应用程序，这将是最好的前进方向。

确保您的Actor系统从您的解决方案中解压缩到它自己的项目中。在解决方案中创建一个新的Worker角色CloudService项目。

选择Worker角色

我配置我的WorkRole如下：

public class WorkerRole : RoleEntryPoint 
{ 
    private readonly CancellationTokenSource cancellationTokenSource = new CancellationTokenSource(); 
    private readonly ManualResetEvent runCompleteEvent = new ManualResetEvent(false); 
    private static ActorSystem ActorSystemInstance; 
    public override void Run() 
    { 
     Trace.TraceInformation("Game.State.WorkerRole is running"); 

     try 
     { 
      this.RunAsync(this.cancellationTokenSource.Token).Wait(); 
     } 
     finally 
     { 
      this.runCompleteEvent.Set(); 
     } 
    } 

    public override bool OnStart() 
    {                     
     ActorSystemInstance = ActorSystem.Create("GameSystem");    
     // Set the maximum number of concurrent connections 
     ServicePointManager.DefaultConnectionLimit = 12; 

     // For information on handling configuration changes 
     // see the MSDN topic at https://go.microsoft.com/fwlink/?LinkId=166357. 

     bool result = base.OnStart(); 

     Trace.TraceInformation("Game.State.WorkerRole has been started"); 

     return result; 
    } 

    public override void OnStop() 
    { 
     ActorSystemInstance.Terminate(); 
     Trace.TraceInformation("Game.State.WorkerRole is stopping"); 

     this.cancellationTokenSource.Cancel(); 
     this.runCompleteEvent.WaitOne(); 

     base.OnStop(); 

     Trace.TraceInformation("Game.State.WorkerRole has stopped"); 
    } 

    private async Task RunAsync(CancellationToken cancellationToken) 
    { 
     var gameController = ActorSystemInstance.ActorOf<GameControllerActor>("GameController"); 

     while (!cancellationToken.IsCancellationRequested) 
     { 
      Trace.TraceInformation("Working"); 
      await Task.Delay(1000); 
     } 
    } 
} 

而且我HOCON文件（在app.config内）如下：

<akka> 
<hocon> 
    <![CDATA[ 
    akka { 
    loglevel = DEBUG 

    actor { 
     provider = "Akka.Remote.RemoteActorRefProvider, Akka.Remote" 
     debug { 
     receive = on 
     autoreceive = on 
     lifecycle = on 
     event-stream = on 
     unhandled = on 
     } 
    } 


    remote { 
     helios.tcp { 
     transport-class = "Akka.Remote.Transport.Helios.HeliosTcpTransport, Akka.Remote" 
     transport-protocol = tcp 
     enforce-ip-family = true 
     port = xxxx //the port configured in your worker role endpoint 
     hostname = "0.0.0.0" //This is the local hostname of the worker role, using 0.0.0.0 will set the Remote actor to "listen" on all available DNS/IP addresses including the loopback (127.0.0.1) 
     pulic-hostname = "xx.xx.xx.xx" //IP Address OR DNS name, but whatever is set here is what MUST be used in the Actor Selector path on the client in order for proper "association" to occur. I did find that DNS name was required for my application as I was using SignalR as a bridge between the Actor system and the web client. 

     } 
    } 
    } 
    ]]> 
</hocon> 

我们需要在工作人员角色配置中定义我们的端点，以便我们“暴露”我们可以与外界沟通的端口。所以去你的WorkerRole设置。

一旦工作者角色部署，你应该能够确认该端口是telnet'ing到服务器开放和可用通过它的IP和端口，你以前配置。

与我们的客户设置我们ActorSelection最重要的部分是IP/DNS地址如下必须匹配与IP/DNS辅助角色

ActorReferences.GameController = 
      ActorSystem.ActorSelection("akka.tcp://GameSystem@xx.xxx.xxx.xxx:8091/user/GameController") 
       .ResolveOne(TimeSpan.FromSeconds(3)) 
       .Result; 

内的公共主机名设置中设置的HOCON配置

为了完整这里是我的客户HOCON配置：

akka { 
    loglevel = OFF 

    actor { 
     provider = "Akka.Remote.RemoteActorRefProvider, Akka.Remote" 
     debug { 
     receive = on 
     autoreceive = on 
     lifecycle = on 
     event-stream = on 
     unhandled = on 
     } 
    } 


    remote { 
     helios.tcp { 
     transport-class = "Akka.Remote.Transport.Helios.HeliosTcpTransport, Akka.Remote" 
     transport-protocol = tcp 
     enforce-ip-family = true 
     port = 0 //A port will be provided for us... not important as we won't be calling into the client externally 
     public-hostname = "yoursitename.azurewebsites.net" //Remember this is simply the DNS name of the client machine 
     hostname = "127.0.0.1" 
     } 
    } 
    } 

我真的希望这可以帮助别人那里。我没有发现很多描述Azure的部署到Azure的文档（没有将Actor系统部署到易失性的IIS应用服务）。让我知道我是否可以以任何方式改进答案。
