登录 Kubernetes 仪表盘

默认情况下Kubernetes仪表盘有两种登录方式,kubeconfig和Token.下面记录一下基于Token的登录方法

按照搜索的结果操作下来登录的账号权限比较低,估计是版本原因吧.secrets的位置发生了改变

# kubectl -n kubernetes-dashboard get secrets 
NAME                               TYPE                                  DATA   AGE
admin-user-token-vmb25             kubernetes.io/service-account-token   3      59d
....

结果里隐去了部分不必要的信息.指的注意的是命名空间kubernetes-dashboard,如果你用命名空间kube-system,也会查到一些secrets.使用命名空间kube-system下的token登录的话,大概率会发现权限不足,无法查看全部信息
