问题描述

我有两个节点，每个节点上都安装了具有Mesos，Marathon和Zookeeper的docker.这是我在主节点上的docker compose文件:

version: '3.7'
 services:
  zookeeper:
   image: ubuntu_mesos_home_marzieh
   command: /home/zookeeper-3.4.8/bin/zkServer.sh restart
  environment:

  ports:

    - 2888:2888
    - 3888:3888

 master-mesos:
  image: ubuntu_mesos_home_marzieh
  command: bash -c "sleep 30; /home/mesos-1.7.0/build/bin/mesos- 
    master.sh --ip=150.20.11.133 --work_dir=/var/run/mesos 
    --hostname=150.20.11.133" 
  privileged: true
  restart: always
  network_mode: host
  depends_on:
    - zookeeper
  environment:
    - LIBPROCESS_IP=150.20.11.133

    - MESOS_QUORUM=1

    - 8080
  ports:
    - 5050:5050
    - 4040:4040
    - 7077:7077
    - 8080:8080

 marathon:

  command: bash -c "sleep 60; /usr/share/marathon/bin/marathon"
  privileged: true
  network_mode: host
  depends_on:
    - zookeeper
    - master-mesos
  environment:
    - HOSTNAME="150.20.11.133"
    - MARATHON_ZK=zk://150.20.11.133:2190/marathon
    - MARATHON_MASTER=zk://150.20.11.133:2190/mesos

  expose:
    - 8080
    - 2190
  ports:
    - 8080:8080
    - 2190:2190

这是docker组成的从节点:

 version: '3.7'
  services:
   zookeeper:
     image: ubuntu_mesos_home_marzieh
     command: /home/zookeeper-3.4.8/bin/zkServer.sh start

  slave-mesos:
     image: ubuntu_mesos_home_marzieh
     command: bash -c "sleep 40; /home/mesos-1.7.0/build/bin/mesos-

   marathon:
    image: ubuntu_mesos_home_marzieh
    command: bash -c "sleep 60; /usr/share/marathon/bin/marathon"
    privileged: true
    network_mode: host
    depends_on:
      - zookeeper
      - slave-mesos
    environment:
      - MARATHON_ZK=zk://150.20.11.133:2190/marathon
      - MARATHON_MASTER=zk://150.20.11.133:2190/mesos

      - 2190
    ports:
      - 8080:8080
      - 2190:2190

我在"zoo.cfg"上配置了Zookeeper，并为每个节点制作了"myid"文件.我也配置了Mesos和Marathon.但是当我在主节点(150.20.11.133)上运行docker compose时，出现了此错误:

marathon_1 | java.net.ConnectException:连接被拒绝 marathon_1 |在sun.nio.ch.SocketChannelImpl.checkConnect(本机方法)

我不知道会发生什么.我尝试使用 ufw 打开每个端口，或者我禁用了防火墙，但是错误并没有消失.您能告诉我docker compose文件怎么了吗?

任何帮助将不胜感激.

谢谢.

解决方案

我刚刚重新启动了"zookeeper"，一切正常.

./ZOOKEEPER_HOME/bin/zkServer.sh restart

I have two nodes that each one has docker with Mesos,marathon,and zookeeper have been installed on it. This is my docker compose file on master node:

version: '3.7'
 services:
  zookeeper:
   image: ubuntu_mesos_home_marzieh
   command: /home/zookeeper-3.4.8/bin/zkServer.sh restart

This is docker compose for slave node:

I configured Zookeeper on "zoo.cfg" and made "myid" file for every node. Also I configured Mesos and Marathon. But when I ran docker compose on master node (150.20.11.133), I got this error:

marathon_1 | java.net.ConnectException: Connection refused marathon_1 | at sun.nio.ch.SocketChannelImpl.checkConnect(Native Method)

I don't know what happen. I tried to open every port with ufw or I disabled firewall, but error did not go away. Would you please tell me what is wrong with docker compose file?

Any help would be appreciated.

Thanks.

解决方案

I just restarted "zookeeper" and everything went fine.

./ZOOKEEPER_HOME/bin/zkServer.sh restart
