java - Vertx: Why is there no clustered verticle? -

im messing around 2 verticles , want start in clustered mode.

here start-methods of 2 verticles:

first verticle:

public static void main(string[] args) {     vertxoptions options = new vertxoptions();      options.setclustered(true);     options.setclustermanager(new hazelcastclustermanager());      vertx.clusteredvertx(options, res -> {         vertx vertx = res.result();         vertx.deployverticle(new walzenschnittblmock());      });  } 

second verticle:

public void start() {     vertxoptions options = new vertxoptions();      vertx.clusteredvertx(options, res -> {         vertx = res.result();         vertx.deployverticle(serviceverticle, this::completeregister);     }); } 

thhis 2 verticles reside on different machines, not "see" each other, although there in clustered mode....is there problem..have missed something?

i found solution:

i have 2 machines , each of them have 4 networkcards - , vertx seems choose wrong one. forced set ip-adress vertx should use. result looks ipadress argument of jar-file :

vertxoptions options = new vertxoptions();      config config = new config();     networkconfig networkconfig = config.getnetworkconfig();      networkconfig.getinterfaces().setenabled(true).addinterface(args[0]);     options.setclustermanager(new hazelcastclustermanager(config));     options.setclustered(true);     options.setclusterhost(args[0]);      vertx.clusteredvertx(options, res -> {         vertx vertx = res.result();         vertx.deployverticle(new receiver());      });
