Kubernetes example deploys defective etcd cluster #13

The Kubernetes example conveniently glosses over the fact that the etcd-cluster.ymlconfig has zero resilience against failed nodes! The file deploys 3 etcd pods which act as a cluster, which is great. But if I stop any of these pods on Kubernetes and then try to deploy them again, the cluster doesn't recognize them! They cannot join the cluster anymore, so the "scaling" is just a facade.

I wanted to create a replicaset or deployment but for some reason , I can't manage to have the pods work well with the service... I don't know why using pods was for at the first place.. sometimes pods goes down by themselves as marked complete ..
