Kubernetes--学习笔记-3-Kubernetes Web UI部署
一、Kubernetes集群环境
请参考Kubernetes--学习笔记-安装配置和服务部署-2
二，创建kubernetes-dashboard.yaml
在master服务器上创建kubernetes-dashboard.yaml文件，并输入以下内容：

[root@master cloud]# 查看service 信息：
[root@master cloud]# kubectl describe service/kubernetes-dashboard --namespace="kube-system"
Name: kubernetes-dashboard
Namespace: kube-system
Labels: app=kubernetes-dashboard
Selector: app=kubernetes-dashboard
Type: NodePort
IP: 10.254.85.224
Port: 80/TCP
NodePort: 30943/TCP
Endpoints: 172.17.0.3:9090
Session Affinity: None
No events.
[root@master cloud]# 从kubernetes-dashboard的service详细信息可以看到，该service绑定到了Node节点的30943端口上。现在，通过浏览器访问该端口就能看到Kubernetes的Web UI:
