Kuberenets Web UI（儀表板）缺失圖形

Question

我已經安裝了Docker v1.13和Kubernetes以及Kubeadm v1.6。然後我安裝了Web UI（Dashboard）。我可以訪問它，但缺少CPU /內存使用情況圖表......爲什麼會發生這種情況？

Answer 1

對我來說，一旦我安裝了heapster作爲附件，使用圖表就可以工作。 Heapster需要一個influxdb作爲度量存儲的數據池。

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幸運的是，你可以用在kube-system命名空間下定義K8S部署所有這些容易（與K8S 1.4.6測試過） ：

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

     emptyDir: {} 
     containers:
