Docker搭建Zookeeper集群问题总结

使用docker-compose搭建zk集群遇到的一些问题及解决方案

services:
  zoo1:
    image: zookeeper
    restart: always
    hostname: zoo1
    container_name: zookeeper_1
    #domainname: 
    ports:
      - 2181:2181
    volumes:
      - /home/data/test/docker:/data
    environment:
      ZOO_MY_ID: 1
      ZOO_SERVERS: server.1=zoo1:2888:3888 server.2=zoo2:2888:3888 server.3=zoo3:2888:3888

  zoo2:
    image: zookeeper
    restart: always
    hostname: zoo2
    container_name: zookeeper_2
    ports:
      - 2182:2181
    volumes:
      - /home/data/test/docker:/data
    environment:
      ZOO_MY_ID: 2
      ZOO_SERVERS: server.1=zoo1:2888:3888 server.2=zoo2:2888:3888 server.3=zoo3:2888:3888

  zoo3:
    image: zookeeper
    restart: always
    hostname: zoo3
    container_name: zookeeper_3
    ports:
      - 2183:2181
    volumes:
      - /home/data/test/docker:/data
    environment:
      ZOO_MY_ID: 3
      ZOO_SERVERS: server.1=zoo1:2888:3888 server.2=zoo2:2888:3888 server.3=zoo3:2888:3888
Docker-compose.yml

这是从网上随便找了一个集群搭建的命令，执行 docker-compose -f Docker-compose.yml up -d  报错

错误详情

错误原因，直接看报错好像是hostname解析不到，ip

BindException: Cannot assign requested address (Bind failed)

于是乎我就直接将hostname去掉，环境变量配置成172.17.0.2 ～ 172.17.0.4启动还是不好使。

错误原因：volume配置问题。

将volume去掉，或者配置成  ./log/txt.log:/txt.lg就可以了。

=================================================

其实我的计划是将本地当前挂载到docker上容器中去，但目前我只找到了将本地文件copy过去的方法。后续试下利用cmd先在容器中创建目录，然后在挂载目录能不能好使，我怀疑是/data目录不能默认帮我创建
