title: Kube-dns does not resolve external hosts on kubeadm bare-metal cluster
body: <p>I've got a k8n cluster setup on a bare-metal ubuntu 16.04 cluster using weave networking with kubeadm.  I'm having a variety of little problems, the most recent of which is that I realized that kube-dns does not resolve external addresses (e.g. google.com).  Any thoughts on why?  Using kube-adm did not give me a lot of insight into the details of that part of the setup.</p>
