Hazecast-Kubernetes Springboot 应用嵌入式集群警告

Question

我已经在 kubernetes 上部署了嵌入式 Hazelcast 集群，但低于警告。 禁用自动增量标志和 portCount 仍然出错。

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>");

我已经在 kubernetes 中打开了容器端口。 服务能够创建集群，但不断收到以下警告。

不知道为什么连接在这里发生

[22.249.47.234]:5701 [cache-cluster] [4.0.1] Connection[id=4, **/22.249.47.234:5701->/22.249.55.1:52736**, qualifier=null, endpoint=null, alive=false, connectionType=NONE] closed. Reason: Exception in Connection[id=4, **/22.249.47.234:5701->/22.249.55.1:52736**, qualifier=null, endpoint=null, alive=true, connectionType=NONE], thread=hz.silly_lalande.IO.thread-in-0 

是否缺少任何配置？

Answer 1

这看起来类似于https://github.com/hazelcast/hazelcast-kubernetes/issues/186将containerPort: 5701添加到您的 HZ 服务清单应该可以工作。

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，您能否确认集群也能正常工作？
