etcd on Kubernetes

This is an example setting up etcd as a set of pods and services running on top of kubernetes. Using:

$ kubectl create -f etcd.yml 
services/etcd-client
pods/etcd0
services/etcd0
pods/etcd1
services/etcd1
pods/etcd2
services/etcd2
$ # now deploy a service that consumes etcd, such as vulcand
$ kubectl create -f vulcand.yml

TODO:

• create a replication controller like service that knows how to add and remove nodes from the cluster correctly
• use kubernetes secrets API to configure TLS for etcd clients and peers
