Question

我正在尝试创建一个docker-compose文件来运行zookeeper和solr（3节点群集-官方映像）。我正在尝试使用撰写文件中的“命令”属性在zookeeper中定义一个znode。

command: bash -c "/apache-zookeeper-3.5.8-bin/bin/zkCli.sh -server zoo1:2181 create /solr '' && zkServer.sh start-foreground"

使用此命令的zookeeper节点不断崩溃。

我的docker compose文件是：

从我看来，用于启动容器中的zookeeper的命令的第二部分未执行，但我不知道为什么？并且还有其他方法可以实现这一目标吗？

找到原因。命令选项中的“ zkServer.sh start-foreground”之前缺少“ exec”。执行命令后导致容器关闭。感谢@Yoeri Van Nieuwerburg提供的示例撰写文件进行比较。

Answer 1

我可能在这里丢失了一些东西，但是我不确定为什么要在Zookeeper实例上“创建” solr目录？
Solr只是一个实例，它连接到zookeeper节点，对吧？
还是要在集成系统中连接多个系统？如果是这样的话，我认为您应该签出this solr-doc，它准确地表明了这一点（“使用chroot”）。

无论如何，如果您只想在不使用/solr端点的情况下启动并运行它，这就是我的一个zookeeper节点在docker-compose中的样子（仅用于本地开发）：

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=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"

您唯一需要在solr-service中更改的是zoo3的URL，它从zoo3:2181/solr到zoo3:2181 ...已经被其他2个节点使用了；）

所有节点都使用相同的设置（当然，命名和ZOO_SERVERS环境变量除外：））

希望这对您有所帮助，希望我没有让您感到困惑；）

如何使用撰写文件中的“命令”在docker撰写群集上创建znode？
