安装
# 1.先将镜像文件上传到两个worker节点，然后解压
docker load -i dashboard_2_0_0.tar.gz
docker load -i metrics-scrapter-1-0-1.tar.gz
# 2.将kubernetes-dashboard.yaml上传到master节点
kubectl apply -f kubernetes-dashboard.yaml

# 3.yaml配置将dashboard安装在了kubernetes-dashboard命名空间下
kubectl get pods -n kubernetes-dashboard
# 4.查看网络配置
kubectl get svc -n kubernetes-dashboard
# 显示如下Running即可
      NAME                     READY  STATUS   RESTARTS    AGE
dashboard-metrics-scraper-xxx   1/1   Running     0        7m14s
kubernetes-dashboard-xxx        1/1   Running     0        6m55s

# 5.修改 service type 类型变成 NodePort
kubectl edit svc kubernetes-dashboard -n kubernetes-dashboard
# 把 type: ClusterIP 变成 type: NodePort，保存退出即可。

kubectl get svc -n kubernetes-dashboard
# 显示如下:NodePort中30940即为访问端口
NAME            TYPE    CLUSTER-IP      EXTERNAL-IP    PORT(S)        AGE
dashboard-xx   ClusterIP  10.10.182.138   <none>       8000/TCP       25m

UI创建Pod

通过Nginx示例，上传镜像到两个worker节点，并解压

UI界面上：右上角加号 -->> create from form -->>填写完毕，点击Deploy -->> 等待启动

–>> 点击左侧 Service菜单，查看映射端口 -->>浏览器打开验证

nodeport                       #是集群外流量访问集群内服务的端口

有时候，自动映射外部访问端口失败，手工修改
