有没有办法删除kubernetes中现有的角色？我在为用户创建角色时犯了一个错误，现在我想更新或删除该角色。请告诉我的方法
删除角色：
kubectl delete role NAME_OF_ROLE -n NAMESPACE
删除角色绑定：
kubectl delete rolebinding NAME_OF_ROLEBINDING -n NAMESPACE
更新角色：
kubectl apply -f NEW_YAML_FILE_FOR_ROLE
更新角色绑定：
kubectl apply -f NEW_YAML_FILE_FOR_ROLEBINDING
kubectl get clusterroles
kubectl get clusterrolebindings
find your role name and then delete
kubectl delete clusterrolebinding name
kubectl delete clusterrole name
