节点没有找到彼此定向的DB Kubernetes群集

问题是,当我检查所有pod的日志时,看起来每个pod都创建了自己的集群,而不是加入单个集群。 原因可能是什么?

Hazelcast.xml配置如下所示:

<hazelcast xsi:schemaLocation="http://www.hazelcast.com/schema/config hazelcast-config-3.3.xsd"
           xmlns="http://www.hazelcast.com/schema/config" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
  <properties>
    <property name="hazelcast.discovery.enabled">true</property>
  </properties>
  <network>
    <join>
      <!-- deactivate normal discovery -->
      <multicast enabled="false"/>
      <tcp-ip enabled="false"/>
      <!-- activate the Kubernetes plugin -->
      <discovery-strategies>
        <discovery-strategy enabled="true"
                            class="com.hazelcast.kubernetes.HazelcastKubernetesDiscoveryStrategy">
          <properties>
            <property name="service-dns">orientdbservice.default.svc.cluster.local</property>
            <property name="service-dns-timeout">10</property>
          </properties>
        </discovery-strategy>
      </discovery-strategies>
    </join>
  </network>
</hazelcast> 

我使用服务dns名称作为方法之一,使用Hazelcast插件与Kubernetes。
