<p>As per <a href="https://kubernetes.io/docs/tasks/tools/install-kubectl/#before-you-begin" rel="noreferrer">https://kubernetes.io/docs/tasks/tools/install-kubectl/#before-you-begin</a>:</p>

<blockquote>
  <p>You must use a kubectl version that is within one minor version difference of your cluster. For example, a v1.2 client should work with v1.1, v1.2, and v1.3 master. Using the latest version of kubectl helps avoid unforeseen issues.</p>
</blockquote>

<p>So you need to either downgrade your kubectl version or upgrade your cluster version.</p>

As per <https://kubernetes.io/docs/tasks/tools/install-kubectl/#before-you-begin>:

> You must use a kubectl version that is within one minor version difference of your cluster. For example, a v1.2 client should work with v1.1, v1.2, and v1.3 master. Using the latest version of kubectl helps avoid unforeseen issues.

So you need to either downgrade your kubectl version or upgrade your cluster version.

It looks like your k8s cluster has not been deployed well. I have verified that it works to deploy the nginx by using the template as defined in the question.
In contrast to your cluster, the cluster I am using has several k8s images to host the dashboard etc.
        "Images": [
            {
                "Names": [
                    "gcr.io/google_containers/kubernetes-dashboard-amd64:v1.6.3"
                ],
                "SizeBytes": 138972432
            },
            {
                "Names": [
                    "gcr.io/google_containers/kubernetes-dashboard-amd64@sha256:71a0de5c6a21cb0c2fbcad71a4fef47acd3e61cd78109822d35e1742f9d8140d",

                ],
                "SizeBytes": 119155776
            },

Also in order to deploy images, at least some namespaces should be returned. 
$ kubectl get ns
NAME          STATUS    AGE
default       Active    37m
kube-public   Active    37m
kube-system   Active    37m
