Akka+Scala: Deploying an actor remotely

In my use case, I have a variable number of independent ActorSystems. As a new system starts up, it initiates a simple Syn/Ack procedure with the command and control system, allowing the C&C to deploy remote actors. Just for fun, here is some example code.

Lets start with our remote system:

object Remote extends App{
 val system = ActorSystem("RemoteSystem",
   ConfigFactory.defaultReference(getClass.getClassLoader))
 val connStr = "akka://CommandSystem@<ip>:2555/user/CommandActor"
 val cnc = system.actorFor(connStr)
 val synActor = system.actorOf(Props[SynActor])
}

class SynActor extends Actor{
 override def preStart = {
  //Send the syn
  Remote.cnc ! new Syn
 }
 def receive = {
  case a:Ack => //
 }
}

Some shared classes:

case class Syn()
case class Ack()

Now the Command and Control system and the actual code you want run remotely:

object Command extends App{
 val system = ActorSystem("CommandSystem",
   ConfigFactory.defaultReference(getClass.getClassLoader))
 val cncActor = system.actorOf(Props[CommandActor])
}

class CommandActor extends Actor {
 def receive = {
  case s:Syn =>
   //Respond for politeness
   sender ! new Ack   
   //Get the remote actorsystem path
   val addr = AddressFromURIString(sender.path.root.toString)  
   //Push the actor to the remote system
   val remoteActor = context.actorOf((Props[RemoteActor]).withDeploy(
     Deploy(scope = RemoteScope(addr)))) 
 }
}

class RemoteActor extends Actor {
 //Where you put your remote code implementation
}

From here, you can handle management of remote actors in whichever way you want. Fun stuff!
