dgrove-oss commented on issue #141: Add a membership management using the discovery URL: https://github.com/apache/incubator-openwhisk-package-alarms/pull/141#issuecomment-376241337 I think on kubernetes we would do this differently. More like how we are deploying the controllers. I do not think we would need to use a discovery service. We would deploy the alarm provider as a [StatefulSet ](https://kubernetes.io/docs/concepts/workloads/controllers/statefulset/) with the number of replicas desired for redundancy. We would define a Kubernetes service to provide a stable way for clients of the alarm packge to talk to its instances. If the instances needed to communicate with each other for their own internal reasons (for example like the AKKA clustering we do with the controller), they would use logical names like alarmservice-0.alarmservice.openwhisk, alarmservice-1.alarmservice.openwhisk, etc. Kubernetes will automatically updates its internal DNS tables to map from these names to the actual ip addresses for the currently running containers.
