Machines should download and network boot CoreOS in about a minute. It can take 2-3 minutes for the Kubernetes API to become available and for add-on pods to be scheduled.
## Kubernetes Dashboard
Access the Kubernetes Dashboard with `kubeconfig` credentials by port forwarding to the dashboard pod.
$ kubectl --kubeconfig=examples/assets/tls/kubeconfig port-forward kubernetes-dashboard-v1.1.0-SOME-ID 9090 --namespace=kube-system
Forwarding from 127.0.0.1:9090 -> 9090
Then visit [http://127.0.0.1:9090](http://127.0.0.1:9090/).
