kops: Unable to use kubelet reserved resources

kops version

• my dev branch, have not validated on the master, but I have not changed this code
• k8s version 1.8
• on ec2

I am getting the error from kubelet: failed to run Kubelet: cannot reserve "storage" resource Here is the relevant cluster spec section that I am having problems with:

  kubelet:
    kubeReserved:
        cpu: "100m"
        memory: "100Mi"
        storage: "1Gi"
    kubeReservedCgroup: "/kube-reserved"
    systemReserved:
        cpu: "100m"
        memory: "100Mi"
        storage: "1Gi"
    systemReservedCgroup: "/system-reserved"
    enforceNodeAllocatable: "pods,system-reserved,kube-reserved"

cluster is being created using kops create -f mycluster.yaml

Expected behavior is that the kubectl start using reserved resources.
