使用Docker的Zookeeper集群模式出错？

Question

我想在不同的主机上使用docker部署zookeeper集群。我使用下一个docker-compose，在host2的host1 zoo2和host3的zoo3中运行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 

的代码是从补充说：https://github.com/31z4/zookeeper-docker

我只是下一个尝试泊坞窗，撰写过了，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，如果我检查状态：

./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的左侧部分rt是主机的本地端口，只能使用一次。此外，您不必暴露港口集装箱互连，因为它们是同一个网络。

因此，删除左边的部分2888:2888，将其保留为：2888，然后docker将在主机中找到一个空闲端口（使用docker ps找出它）。或者直接删除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
