k8s入门系列之扩展组件(二)kube-ui安装篇

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
