title: usecase for etcd inside Kubernetes
body: <p>I was just wondering, why it is useful to run etcd cluster <a href="https://github.com/kubernetes/charts/tree/master/incubator/etcd" rel="nofollow noreferrer">inside Kubernetes</a>, when Kubernetes itself <a href="https://kubernetes.io/docs/concepts/overview/components/#etcd" rel="nofollow noreferrer">depends on etcd</a>. </p>
  
  <p>It just does not make sense to me, as if I have HA Kube, I am also forced to have HA etcd outside. Hence to reason to install it again inside... </p>
