kubernetes - org.apache.catalina.ha.tcp.ReplicationValve.sendReplicationMessage 无法在 kind 集群中执行复制请求

Question

我正在使用 Kubernetes 集群（使用 kind）并尝试“提升和转移”基于 jsf 的应用程序。我已经设法将应用程序部署到一个容器中，目前，我正在尝试在 kubernetes 中实现一个 Tomee 集群。

我已经成功创建了用于 DNS 查找的 Tomcat 服务 ingress-nginix，并使用 CloudMembershipService 配置了 tomee：

<Cluster className="org.apache.catalina.ha.tcp.SimpleTcpCluster" channelSendOptions="6">
       <Channel className="org.apache.catalina.tribes.group.GroupChannel">
         <Membership className="org.apache.catalina.tribes.membership.cloud.CloudMembershipService"
            membershipProviderClassName="org.apache.catalina.tribes.membership.cloud.DNSMembershipProvider"
             />
         <Valve className="org.apache.catalina.ha.tcp.ReplicationValve"
             filter=".*\.gif|.*\.js|.*\.jpeg|.*\.jpg|.*\.png|.*\.htm|.*\.html|.*\.css|.*\.txt"/>    
       </Channel>
     </Cluster>

当我启动一个节点时，一切都很好，应用程序响应并且我看不到任何相关问题。此时（节点 1 已打开会话）我尝试扩展添加节点：我可以看到 pod 即将启动，正在部署的应用程序以及集群内的通信开始并使用集群成员资格，但随后我得到了 NullPointerException并且没有堆栈跟踪：

起初，我认为问题在于节点端口未公开，但我的配置是

...
    ports:
    - containerPort: 8080
    - containerPort: 4000
...

谁能指出我正确的方向？
