Question

我想设置版本为3.5.1的3节点zookeeper群集。为了将它部署到kubernetes，我必须使zookeeper节点本身为0.0.0.0，因此它可以正确启动。配置如下：

ZK1 ： zoo.cfg

    standaloneEnabled=false
    dynamicConfigFile=/opt/zookeeper/conf/zoo.cfg.dynamic

zoo.cfg.dynamic

    server.1=0.0.0.0:2888:3888:participant;2181
    server.2=10.62.56.192:2889:3889:participant;2182
    server.3=10.62.56.192:2890:3890:participant;2183

ZK2 ： zoo.cfg

    standaloneEnabled=false
    dynamicConfigFile=/opt/zookeeper/conf/zoo.cfg.dynamic

zoo.cfg.dynamic

    server.1=10.62.56.192:2888:3888:participant;2181
    server.2=0.0.0.0:2889:3889:participant;2182
    server.3=10.62.56.192:2890:3890:participant;2183

ZK3 ： zoo.cfg

    standaloneEnabled=false
    dynamicConfigFile=/opt/zookeeper/conf/zoo.cfg.dynamic

zoo.cfg.dynamic

   server.1=10.62.56.192:2888:3888:participant;2181
   server.2=10.62.56.192:2889:3889:participant;2182
   server.3=0.0.0.0:2890:3890:participant;2183

结果只能启动zk1，zk2和zk3无法启动。错误是

   org.apache.zookeeper.server.quorum.QuorumPeerConfig$ConfigException: client address for this server (id = 2) in static config file is 0.0.0.0/0.0.0.0:2181 is different from client address found in dynamic file: /0.0.0.0:2182
    at org.apache.zookeeper.server.quorum.QuorumPeerConfig.setupClientPort(QuorumPeerConfig.java:608)
    at org.apache.zookeeper.server.quorum.QuorumPeerConfig.setupQuorumPeerConfig(QuorumPeerConfig.java:506)
    at org.apache.zookeeper.server.quorum.QuorumPeerConfig.parse(QuorumPeerConfig.java:157)
    at org.apache.zookeeper.server.quorum.QuorumPeerMain.initializeAndRun(QuorumPeerMain.java:110)
    at org.apache.zookeeper.server.quorum.QuorumPeerMain.main(QuorumPeerMain.java:79)

配置无效，异常退出

关键是我们必须将节点本身配置为0.0.0.0。

尝试：https://hub.docker.com/r/elevy/zookeeper/基于https://github.com/eliaslevy/docker-zookeeper

每个zk pod使用1个服务。每个服务都有自己的“主机名”，可以通过DNS从每个zk pod中解析。名称是zookeeper-1，zookeeper-2和zookeeper-3。

所以，而不是像

这样的配置行

server.1=0.0.0.0:2888:3888:participant;2181
server.2=10.62.56.192:2889:3889:participant;2182 
server.3=10.62.56.192:2890:3890:participant;2183

你有如下的配置行：

server.1=zookeeper-1:2888:3888
server.2=zookeeper-2:2888:3888
server.3=zookeeper-3:2888:3888

请注意，由于每个Pod都有自己的IP，因此您无需使用一系列端口，例如2888,2889,2890。您可以为每个端口使用2888/3888。

无法在kubernetes中部署Zookeeper 3.5.1
