hazelcast-kubernetes Network Discovery: How to use with Multiple Nodes
Could you try with service dns name as:
myapp.mynamespace.endpoints.cluster.local
Please reply it's work or not and also post your full log.
I know it's kinda happened long time ago. But the problem here was using wrong class name for discovery strategy.
It should be com.hazelcast.kubernetes.HazelcastKubernetesDiscoveryStrategy
