泊坞窗中的akka节点显式取消关联

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中的远程配置为：

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]
  }
}

在topGatewayBackend中是：

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]]由以下原因引起：[远程系统显式取消关联(原因未知).]

docker run命令为：
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-快照

我想知道如何使前端与后端成功关联.

预先感谢您的耐心解答.

最佳答案

检查此如何在docker中运行akka集群：http://blog.michaelhamrah.com/2014/06/akka-clustering-with-sbt-docker-and-sbt-native-packager/

一个简单的答案是,akka群集要求该地址必须与内部和外部地址一致.因此,在docker中启动akka应用程序时,需要使用为容器动态创建的内部ip地址.

您需要具有以下启动脚本：

#!/bin/bash

CLUSTER_IP=`/sbin/ifconfig eth0 | grep 'inet addr:' | cut -d: -f2 | awk '{ print $1 }'` $@

将其放入您的docker容器中,并在akka配置中使用CLUSTER_IP环境变量作为其群集主机地址.

更新：
在docker 1.10版本中,由于添加了新的网络功能,因此不需要启动脚本.您可以只使用容器的名称作为参考,而docker会为您修复地址.
