Question

我已经使用Kubeadm v1.6安装了Docker v1.13和Kubernetes。然后我安装了Web UI（仪表板）。我可以访问它，但它缺少CPU /内存使用情况图......为什么会发生这种情况？

对我来说，一旦我将heapster作为插件安装，使用图就会起作用。 Heapster需要使用Influxdb作为度量存储的数据接收器。幸运的是，您可以使用kube-system命名空间中的以下定义（使用k8s 1.4.6对其进行测试）在k8中轻松部署所有这些内容：

<强> heapster-service.yml：

apiVersion: v1
kind: Service
metadata:
  labels:
    task: monitoring
    # For use as a Cluster add-on (https://github.com/kubernetes/kubernetes/tree/master/cluster/addons)
    # If you are NOT using this as an addon, you should comment out this line.
    kubernetes.io/cluster-service: 'true'
    kubernetes.io/name: Heapster
  name: heapster
  namespace: kube-system
spec:
  ports:
  - port: 80
    targetPort: 8082
  selector:
    k8s-app: heapster

<强> heapster-deployment.yml：

apiVersion: extensions/v1beta1
kind: Deployment
metadata:
  name: heapster
  namespace: kube-system
spec:
  replicas: 1
  template:
    metadata:
      labels:
        task: monitoring
        k8s-app: heapster
        version: v6
    spec:
      containers:
      - name: heapster
        image: kubernetes/heapster:canary
        imagePullPolicy: Always
        command:
        - /heapster
        - --source=kubernetes:https://kubernetes.default
        - --sink=influxdb:http://monitoring-influxdb:8086

<强> influxdb-service.yml：

    # For use as a Cluster add-on (https://github.com/kubernetes/kubernetes/tree/master/cluster/addons)
    # If you are NOT using this as an addon, you should comment out this line.
    kubernetes.io/cluster-service: 'true'
    kubernetes.io/name: monitoring-influxdb
  name: monitoring-influxdb
  namespace: kube-system
spec:
  # type: NodePort
