Hazecast-Kubernetes Springboot application embedded cluster warning

10/29/2020

i have deploy embedded hazelcast cluster on kubernetes, i am getting below warning. disabled auto increment flag and portCount still getting error.

Config :

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>");

i have opened container port in kubernetes. services are able to create the cluster but getting the below warning continuously.

[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.

This looks similar to https://github.com/hazelcast/hazelcast-kubernetes/issues/186 Adding containerPort: 5701 to your HZ service manifest should work.

It should work irrespective of the type of service whether it is LoadBalancer or ClusterIP

Can you confirm clustering is working fine too even in the case of warnings?
