使用Docker的Zookeeper集羣模式出錯？

Question

我想在不同的主機上使用docker部署zookeeper集羣。我使用下一個docker-compose，在host2的host1 zoo2和host3的zoo3中運行zoo1。

version: '2' 
services: 
    zoo1: 
     image: 31z4/zookeeper 
     restart: always 
     ports: 
      - 2181:2181 
      - 2888:2888 
      - 3888:3888 
     environment: 
      ZOO_MY_ID: 1 
      ZOO_SERVERS: server.1=host1-IP:2888:3888 server.2=host2-IP:2888:3888 server.3=host3-IP:2888:3888 

    zoo2: 
     image: 31z4/zookeeper 
     restart: always 
     ports: 
      - 2182:2181 
      - 2888:2888 
      - 3888:3888 
     environment: 
      ZOO_MY_ID: 2 
      ZOO_SERVERS: server.1=host1-IP:2888:3888 server.2=host2-IP:2888:3888 server.3=host3-IP:2888:3888 

    zoo3: 
     image: 31z4/zookeeper 
     restart: always 
     ports: 
      - 2183:2181 
      - 2888:2888 
      - 3888:3888 
     environment: 
      ZOO_MY_ID: 3 
      ZOO_SERVERS: server.1=host1-IP:2888:3888 server.2=host2-IP:2888:3888 server.3=host3-IP:2888:3888 

的代碼是從補充說：https://github.com/31z4/zookeeper-docker

我只是下一個嘗試泊塢窗，撰寫過了，加zoo1，zoo2和zoo3到/ etc/hosts文件：

version: '2' 
services: 
    zoo1: 
     image: 31z4/zookeeper 
     restart: always 
     ports: 
      - 2181:2181 
      - 2888:2888 
      - 3888:3888 
     environment: 
      ZOO_MY_ID: 1 
      ZOO_SERVERS: server.1=zoo1:2888:3888 server.2=zoo2:2888:3888 server.3=zoo3:2888:3888 

    zoo2: 
     image: 31z4/zookeeper 
     restart: always 
     ports: 
      - 2182:2181 
      - 2888:2888 
      - 3888:3888 
     environment: 
      ZOO_MY_ID: 2 
      ZOO_SERVERS: server.1=zooo1:2888:3888 server.2=zoo2:2888:3888 server.3=zoo3:2888:3888 

    zoo3: 
     image: 31z4/zookeeper 
     restart: always 
     ports: 
      - 2183:2181 
      - 2888:2888 
      - 3888:3888 
     environment: 
      ZOO_MY_ID: 3 
      ZOO_SERVERS: server.1=zoo1:2888:3888 server.2=zoo2:2888:3888 server.3=zoo3:2888:3888 

但它不工作，如果我檢查狀態：

./bin/zkServer.sh status 
ZooKeeper JMX enabled by default 
Using config: /conf/zoo.cfg 
Error contacting service. It is probably not running. 

Answer 1

暴露po的左側部分rt是主機的本地端口，只能使用一次。此外，您不必暴露港口集裝箱互連，因爲它們是同一個網絡。

因此，刪除左邊的部分2888:2888，將其保留爲：2888，然後docker將在主機中找到一個空閒端口（使用docker ps找出它）。或者直接刪除ports指令，如果你不需要暴露的端口。

version: '2' 
services: 
    zoo1: 
     image: 31z4/zookeeper 
     restart: always 
     ports: 
      - 2181 
      - 2888 
      - 3888 
     environment: 
      ZOO_MY_ID: 1 
      ZOO_SERVERS: server.1=zoo1:2888:3888 server.2=zoo2:2888:3888 server.3=zoo3:2888:3888 

    zoo2: 
     image: 31z4/zookeeper 
     restart: always 
     ports: 
      - 2181 
      - 2888 
      - 3888 
     environment: 
      ZOO_MY_ID: 2 
      ZOO_SERVERS: server.1=zoo1:2888:3888 server.2=zoo2:2888:3888 server.3=zoo3:2888:3888 

    zoo3: 
     image: 31z4/zookeeper 
     restart: always 
     ports: 
      - 2181 
      - 2888 
      - 3888 
     environment: 
      ZOO_MY_ID: 3 
      ZOO_SERVERS: server.1=zoo1:2888:3888 server.2=zoo2:2888:3888 server.3=zoo3:2888:3888
