我们有一个c#胖客户端，需要修改它来连接Kubernetes中的Apache Ignite集群节点。c#胖客户端将在Kubernetes之外的Windows机器上运行。我们可以使用spring.xml配置中定义的TcpDiscoveryKubernetesIpFinder或使用任何其他方法来实现这一点吗?
在c#厚客户端访问负载均衡器ip和发现端口时出现以下错误，

下面是配置，

由于该厚客户端部署在Kubernetes之外，因此它无法访问k8s服务。您需要显式地为该客户端指定外部节点地址。
另外，按照这里的描述设置forceClientToServerConnections=true选项。
