k8s入门系列之扩展组件(二)kube-ui安装篇-优快云博客

本文介绍如何通过kube-ui实现Kubernetes集群的Web管理界面部署。具体步骤包括定义ReplicationController和Service，并通过浏览器访问指定节点查看节点状态、Pod、RC、SVC等信息。

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@master kube-dashboard]# 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

•创建Pod

[root@master kube-dashboard]# kubectl create -f kubernetes-dashboard-rc.yml

2.编辑kube-dashboard-svc.yml定义文件
[root@master kube-dashboard]# cat kubernetes-dashboard-svc.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

[root@master kube-dashboard]# kubectl create -f kubernetes-dashboard-svc.yml

3.访问192.168.30.20:8080/ui(也就是master节点)，会自动跳转到http://192.168.30.20:8080/api/v1/proxy/namespaces/kube-system/services/kubernetes-dashboard/#/dashboard/，效果如下图
