HazelCast Embded cache members not adding in Openshift with multiple pods

Question

I'm trying to expose hazelcast cache with embedded setup in my service, its works fine in my local, even its able to add members if i tried to run application with multiple ports. Now the same is deployed in OCP (OpenShift) with 2 instance and hazelcast members are not added to each other due to this cache is not updated across the pod. below is the config code which i used for hazelcast.

 @Bean
    public Config hazelcastConfig(){
       return new Config().setInstanceName("hazelcast-instance")
                .addMapConfig(new MapConfig().setName("mycache")
                .setMaxSizeConfig(new MaxSizeConfig(300,MaxSizeConfig.MaxSizePolicy.FREE_HEAP_SIZE))
                .setEvictionPolicy(EvictionPolicy.LRU)
                .setTimeToLiveSeconds(2000));
    }

please let me know any additional configuration need to added, so that members can clustered in openshift

Please read the following resorces:

This should solve all your issues. The simplest configuration you need to add (assuming you added the RBAC) is the following one:

config.getNetworkConfig().getJoin().getMulticastConfig().setEnabled(false);
config.getNetworkConfig().getJoin().getKubernetesConfig().setEnabled(true);
