Typically, an installer for kubernetes (like Red Hat's OpenShift Installer) will co-locate the etcd cluster on the Kubernetes master nodes, which also have the API servers that would be reading/writing to etcd. I'm not sure exactly what you mean by "launch a coreOS cluster using kubernetes." You could run your Kubernetes cluster on top of Container Linux nodes (as CoreOS company did with their Tectonic enterprise Kubernetes product). You could also run an etcd cluster on Container Linux, and create a Kuberenetes cluster running on RHEL that connected to the etcd cluster running on etcd (not sure why you'd do that, just trying to express flexibility). I think splitting out the host operating system, the etcd datastore, the kuberenetes api-server and your applications is a good idea when thinking about Kubernetes architecture.
