问题描述
我已经在kubernetes上部署了嵌入式hazelcast集群，但是我得到的警告不足。禁用了自动递增标志，并且portCount仍然出现错误。
配置：
Config config = new Config();
config.setClusterName("cache-cluster");
JoinConfig joinConfig = config.getNetworkConfig().getJoin();
joinConfig.getMulticastConfig().setEnabled(false);
joinConfig.getTcpIpConfig().setEnabled(false);
joinConfig.getKubernetesConfig().setEnabled(true)
.setProperty("namespace","<Namespace>")
.setProperty("service-name","<Service-name>");
我在kubernetes中打开了容器端口。服务能够创建集群，但会不断收到以下警告。

不确定为什么连接在这里
[22.249.47.234]:5701 [cache-cluster] [4.0.1] Connection[id=4,**/22.249.47.234:5701->/22.249.55.1:52736**,thread=hz.silly_lalande.IO.thread-in-0
是否缺少任何配置？
解决方法
这看起来类似于https://github.com/hazelcast/hazelcast-kubernetes/issues/186 将 containerPort：5701 添加到您的HZ服务清单中应该可以。
无论服务类型是LoadBalancer还是ClusterIP，它都应该工作
即使在出现警告的情况下，您也可以确认集群工作正常吗？
