Solr Cloud无法连接到(随机)Zookeeper节点(完全对接设置)

简介

我正在尝试使用Zookeeper来玩SolrCloud。我知道SolrCloud有它自己的内置Zookeeper，但是由于不推荐使用这种设置，所以我模仿（或者，至少我希望如此）外部Zookeeper集合- Solr Cloud设置（3个ZK节点，2个Solr节点）。
为了便于执行此操作，我创建了以下docker-compose.yml：

version: '3.8'

services:
  zoo1:
    image: library/zookeeper:3.5.7
    container_name: zoo1
    restart: always
    hostname: zoo1
    ports:
      - 8184:8080
    environment:
      TZ: Europe/Paris
      ZOO_MY_ID: 1
      ZOO_SERVERS: server.1=0.0.0.0:2888:3888;2181 server.2=zoo2:2888:3888;2181 server.3=zoo3:2888:3888;2181
    networks:
      - solr
    command: >
      sh -c "ln -snf /usr/share/zoneinfo/$TZ /etc/localtime && 
      echo $TZ > /etc/timezone &&
      sed -i 's/autopurge.purgeInterval=0/autopurge.purgeInterval=1/g' /conf/zoo.cfg  &&
      echo 4lw.commands.whitelist=mntr,conf,ruok >> /conf/zoo.cfg &&
      exec zkServer.sh start-foreground"

  zoo2:
    image: library/zookeeper:3.5.7
    container_name: zoo2
    restart: always
    hostname: zoo2
    ports:
      - 8284:8080
    environment:
      TZ: Europe/Paris
      ZOO_MY_ID: 2
      ZOO_SERVERS: server.1=zoo1:2888:3888;2181 server.2=0.0.0.0:2888:3888;2181 server.3=zoo3:2888:3888;2181
    networks:
      - solr
    command: >
      sh -c "ln -snf /usr/share/zoneinfo/$TZ /etc/localtime &&
      echo $TZ > /etc/timezone &&
      sed -i 's/autopurge.purgeInterval=0/autopurge.purgeInterval=1/g' /conf/zoo.cfg  &&
      echo 4lw.commands.whitelist=mntr,conf,ruok >> /conf/zoo.cfg &&
      exec zkServer.sh start-foreground"

  zoo3:
    image: library/zookeeper:3.5.7
    container_name: zoo3
    restart: always
    hostname: zoo3
    ports:
      - 8384:8080
    environment:
      TZ: Europe/Paris
      ZOO_MY_ID: 3
      ZOO_SERVERS: server.1=zoo1:2888:3888;2181 server.2=zoo2:2888:3888;2181 server.3=0.0.0.0:2888:3888;2181
    networks:
      - solr
    command: >
      sh -c "ln -snf /usr/share/zoneinfo/$TZ /etc/localtime && 
      echo $TZ > /etc/timezone &&
      sed -i 's/autopurge.purgeInterval=0/autopurge.purgeInterval=1/g' /conf/zoo.cfg  &&
      echo 4lw.commands.whitelist=mntr,conf,ruok >> /conf/zoo.cfg &&
      exec zkServer.sh start-foreground"

  solr1:
    image: library/solr:8.6.3
    container_name: solr1
    ports:
      - "8981:8983"
    environment:
       ZK_HOST: zoo1:2181,zoo2:2181,zoo3:2181
    networks:
      - solr
    depends_on:
      - zoo1
      - zoo2
      - zoo3

  solr2:
    image: library/solr:8.6.3
    container_name: solr2
    ports:
      - "8982:8983"
    environment:
      ZK_HOST: zoo1:2181,zoo2:2181,zoo3:2181
    networks:
      - solr
    depends_on:
      - zoo1
      - zoo2
      - zoo3

networks:
  solr:
    name: solr_zookeeper_cluster

所以，使用这个文件，一切都启动得很好很容易。我实际上有3个ZK节点，其中一个是领导者，还有2个Solr节点...

问题

然而（这是我的实际问题）Solr UI在显示ZK状态时表现得有点奇怪。我总是在zkStatus中正好有两个ZK示例没有问题，但正好有一个“不好”...大多数时候，两个Solr节点都有同一个Zookeeper节点的问题，但只要我开始玩（如：停止首项以触发首项选择并重启该特定节点），则它变得相当随机化......。

您不应该使用0.0.0.0，而应该使用dockerfile中定义的主机名。因此，在zoo1配置中，server1应该是zoo1，在zoo2配置中，server2应该是zoo2，在zoo3配置中，服务器应该是zoo3。
