success output

kubectl describe secret admin-user-token-6kcd5 -n kubernetes-dashboard

kubectl edit svc kubernetes-dashboard -n kubernetes-dashboard

修改对应红框参数，又或者一开始进行资源创建的时候就提前完成nodeport的资源定义而不是clusterip。

访问节点IP：隐私错误https://192.168.164.13:30443/#/login

thisisunsafe

页面跳转完成，将相关的secret值赋值粘贴，完成页面跳转

success
