  您需要先下载以下文件：

  curl https://raw.githubusercontent.com/kubernetes/heapster/master/deploy/kube-config/influxdb/grafana.yaml > grafana.yaml
  curl https://raw.githubusercontent.com/kubernetes/heapster/master/deploy/kube-config/influxdb/heapster.yaml > heapster.yaml
  curl https://raw.githubusercontent.com/kubernetes/heapster/master/deploy/kube-config/influxdb/influxdb.yaml > influxdb.yaml
  curl https://raw.githubusercontent.com/kubernetes/heapster/master/deploy/kube-config/rbac/heapster-rbac.yaml > heapster-rbac.yaml
  

  然后创建grafana，Influxdb和heapster的以下服务实例：

  $ kubectl create -f grafana.yaml
  deployment "monitoring-grafana" created
  service "monitoring-grafana" created
  
  $ kubectl create -f heapster.yaml
  serviceaccount "heapster" created
  deployment "heapster" created
  service "heapster" created
  
  $ kubectl create -f influxdb.yaml
  deployment "monitoring-influxdb" created
  service "monitoring-influxdb" created
  
  $ kubectl create -f heapster-rbac.yaml
  clusterrolebinding "heapster" created
  

  按照本教程测试您的自动缩放窗格：

  希望这可以帮助 .

  编辑：部署文件中的资源请求：

  apiVersion: v1
  kind: Pod
  metadata:
    name: frontend
  spec:
    containers:
    - name: db
      image: mysql
      env:
      - name: MYSQL_ROOT_PASSWORD
        value: "password"
      resources:
        requests:
          memory: "64Mi"
          cpu: "250m"
        limits:
          memory: "128Mi"
          cpu: "500m"
    - name: wp
      image: wordpress
      resources:
        requests:
          memory: "64Mi"
          cpu: "250m"
        limits:
          memory: "128Mi"
          cpu: "500m"
  

  资源和请求应该存在于部署文件中，以便HPA可以将其访问为自动缩放 .
