Ладья не может распознать "rook-storageclass.yaml": нет совпадений для rook.io/, Kind=Pool

Question

В моем кластере Kubernetes V1.6.4 при попытке установить пример приложения rook https://github.com/rook/rook/blob/master/Documentation/k8s-block.md

когда я запускаю файл storageclass.yaml, его сообщение об ошибке ниже.

kubectl create -f rook-storageclass.yaml
storageclass "rook-block" created
error: unable to recognize "rook-storageclass.yaml": no matches for rook.io/, Kind=Pool

Вот файл yaml.

 cat rook-storageclass.yaml
apiVersion: rook.io/v1alpha1
kind: Pool
metadata:
  name: replicapool
  namespace: rook
spec:
  replication:
    size: 1
  # For an erasure-coded pool, comment out the replication size above and uncomment the following settings.
  # Make sure you have enough OSDs to support the replica size or erasure code chunks.
  #erasureCode:
  #  codingChunks: 2
  #  dataChunks: 2

apiVersion: storage.k8s.io/v1
kind: StorageClass
metadata:
   name: rook-block
provisioner: rook.io/block
parameters:
  pool: replicapool
  # Specify the Rook cluster from which to create volumes. If not specified, it will use `rook` as the namespace and name of the cluster.
  # clusterName: rook
  # clusterNamespace: rook


 kubectl exec -ti -n rook rook-client -- rook pool ls
NAME          NUMBER    TYPE         SIZE      DATA      CODING    ALGORITHM
rbd           0         replicated   1
replicapool   1         replicated   1

Все стручки работают.

 kubectl get pods -n rook
