Kubernetes Web UI（仪表板）缺少图表答案

【发布时间】：2017-06-09 11:50:00
【问题描述】：

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/内存使用图......为什么会发生这种情况？

【问题讨论】：

您是否将heapster 安装为插件？我认为这是查看图表所必需的 - 至少在 k8s 1.4 中
谢谢，这成功了！ :)

对我来说，一旦我将heapster 作为插件安装，使用图表就可以使用。 Heapster 需要一个 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在 k8s 中轻松部署所有这些（使用 k8s 1.4.6 进行测试）：

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

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

influxdb-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: monitoring-influxdb
  name: monitoring-influxdb
  namespace: kube-system
spec:
  # type: NodePort
  ports:
  - name: api 
    port: 8086
    targetPort: 8086
  selector:
    k8s-app: influxdb

infuxdb-deployment.yml：

apiVersion: extensions/v1beta1
kind: Deployment
metadata:
  name: monitoring-influxdb
  namespace: kube-system
spec:
  replicas: 1
  template:
    metadata:
      labels:
        task: monitoring
        k8s-app: influxdb
    spec:
      volumes:
      - name: influxdb-storage
        emptyDir: {}
      containers:
      - name: influxdb
        image: kubernetes/heapster_influxdb:v0.6
        resources:
          requests:
            memory: "256M"
            cpu: "0.1"
          limits:
            memory: "1G"
            cpu: "1.0"
        volumeMounts:
        - mountPath: /data
          name: influxdb-storage
