# 查看k8s集群中可以使用命名空间隔离的资源

[root@master01 dashboard]# kubectl api-resources -o name --verbs=list --namespaced | xargs -n 1 kubectl get --show-kind --ignore-not-found -n kubernetes-dashboard
[root@master01 dashboard]#

# 使用强制删除(依然无法删除该命名空间)

[root@master01 dashboard]# kubectl  delete ns kubernetes-dashboard --force --grace-period=0
warning: Immediate deletion does not wait for confirmation that the running resource has been terminated. The resource may continue to run on the cluster indefinitely.
