docker中的akka​​节点明确地解除了关联

Question

我在我的项目中使用akka 2.4-M2。我想用docker部署我的项目。但是，当我使用boot2docker测试两个节点时，会出现问题。我的节点无法连接到种子节点。

build.sbt中的配置如下：

lazy val `topGatewayFrontend` = (project in file("topGatewayFrontend"))
  .enablePlugins(PlayScala)
  .enablePlugins(DockerPlugin)
  .settings(
    name := "topGatewayFrontend",
    libraryDependencies ++= (Dependencies.topGatewayFrontend ++ Seq(cache,     ws)),
    dockerExposedPorts := Seq(9000)
  )

lazy val `topGatewayBackend` = (project in file("topGatewayBackend"))
  .enablePlugins(JavaAppPackaging)
  .enablePlugins(DockerPlugin)
  .enablePlugins(UniversalPlugin)
  .settings(
    name := "topGatewayBackend",
    javaOptions in run ++= Seq(
      "-Djava.library.path=./sigar",
      "-Xms128m", "-Xmx512m"),
    // this enables custom javaOptions
    fork in run := true,
    libraryDependencies ++= Dependencies.topGatewayBackend ++ Seq(ws),
    dockerExposedPorts := Seq(9527)
  ).dependsOn(auditApi).aggregate(auditApi)

topGatewayFrontend中的远程配置是：

akka{
  remote {
    log-sent-messages = on
    log-received-messages = on
    netty.tcp {
      hostname = ${?HOSTNAME}
      port = 9527                   # external (logical) port
      bind-hostname = 0.0.0.0
      bind-port = 0
    }
  }
  cluster {
    seed-nodes = ["akka.tcp://application@"${?HOSTNAME}":9527"]
    roles = [topGatewayBackend]
  }
}

topGatewayBackend是：

akka{
  remote {
    log-sent-messages = on
    log-received-messages = on
    netty.tcp {
      hostname = ${?HOSTNAME}
      port = 0              # external (logical) port
      bind-hostname = 0.0.0.0
      bind-port = 0
    }
  }
  cluster {
    seed-nodes = ["akka.tcp://application@"${?HOSTNAME}":9527"]
    roles = [topGatewayFrontend]
  }
}

我得到的日志如下：

在后端：

[INFO] [07/12/2015 03:13:37.568] [application-akka.actor.default-dispatcher-16] [akka.cluster.Cluster(akka://application)] Cluster Node [akka.tcp://application@192.168.59.103:9527] - Metrics collection has started successfully

在前端：

Reason: [Association failed with [akka.tcp://application@192.168.59.103:9527]] Caused by: [The remote system explicitly disassociated (reason unknown).]

问题是 [关联失败[akka.tcp：//application@192.168.59.103：9527]]引起：[远程系统明确解除关联（原因未知）。]

docker run命令是： docker run -e HOSTNAME=192.168.59.103 -p 9527:9527 docker.fenxibao.com/topgatewaybackend:1.0-SNAPSHOT和docker run -p 9000:9000 -e HOSTNAME=192.168.59.103 docker.fenxibao.com/topgatewayfrontend:1.0-SNAPSHOT

我想知道我能做些什么才能使前端合作伙伴成功地与后端合作。

提前感谢您的患者答案。
