kube-ui安装

kube-ui是k8s提供的web管理界面，可以展示节点的内存、CPU、磁盘、Pod、RC、SVC等信息。

1.编辑kube-dashboard-rc.yml定义文件
[root@kubernetes-master pods]# cat kubernetes-dashboard-rc.yml

kind: ReplicationController
apiVersion: v1
metadata:
  labels:
    app: kubernetes-dashboard
  name: kubernetes-dashboard
  namespace: kube-system
spec:
  replicas: 1
  selector:
      app: kubernetes-dashboard
  template:
    metadata:
      labels:
        app: kubernetes-dashboard
    spec:
      containers:
      - name: kubernetes-dashboard
        image: docker.gaoxiaobang.com/kubernetes/kube-ui:v5
        imagePullPolicy: Always
        ports:
        - containerPort: 8080
        livenessProbe:  
          httpGet:  
            path: /  
            port: 8080  
          initialDelaySeconds: 30  
          timeoutSeconds: 5

创建pod

kubectl create -f kubernetes-dashboard-rc.yml

kind: Service
apiVersion: v1
metadata:
  labels:
    app: kubernetes-dashboard
  name: kubernetes-dashboard
  namespace: kube-system
spec:
  type: NodePort
  ports:
  - port: 80
    targetPort: 8080
  selector:
    app: kubernetes-dashboard

创建service

kubectl create -f kubernetes-dashboard-svc.yml

访问master ip 10.64.8.68:8080/ui / 不出问题会直接跳转到http://10.64.8.68:8080/api/v1/proxy/namespaces/kube-system/services/kubernetes-dashboard/#/dashboard/  页面
