I have 2 questions about the orchestrationtool Kubernetes.
1) What is the Kube controller doing? Sometimes I read that it's really creating pods (the API server tells it how). And Sometimes I read it's just watching the whole process and see changes in the etcd.
2) Why do I see the Replication Controller on the Master in so many architecture-overviews of Kubernetes? I thought it was created for a service (which contains pods). So that it's always placed on the node.
