google-compute-engine - 为什么我无法安装 Google Heapster Kubernetes 插件？

Question

我无法安装 cluster/addons/cluster-monitoring/google/heapster-controller.yaml由于以下错误，在 CoreOS 991.1.0/GCE 上使用 Kubernetes 1.2.0:

Error from server: error when creating "/tmp/heapster-controller.yaml": Deployment in version extensions/v1beta1 cannot be handled as a Deployment: json: cannot unmarshal object into Go value of type string What is going wrong here?

我的 heapster-controller.yaml 看起来像这样(从模板扩展):

apiVersion: extensions/v1beta1
kind: Deployment
metadata:
  name: heapster-v1.0.2
  namespace: kube-system
