红帽全球峰会5.9. 列出并显示 DNS 服务拒绝列表
您可以查询 OpenShift (RHOSO) DNS 服务（指定）数据库（指定）数据库并查看特定拒绝列表的所有拒绝列表或显示属性。执行此操作的 OpenStack 客户端命令分别是 openstack zone blacklist list 和 openstack zone blacklist show。
查看所有 denylists 很有用，因为您必须知道 denylist ID 才能使用其他 denylist 命令。
先决条件
-
管理员已为您创建一个项目，并为您提供了一个
clouds.yaml文件来访问云。 python-openstackclient软件包驻留在您的工作站上。$ dnf list installed python-openstackclient
流程
确认为您的云设置了系统
OS_CLOUD变量：$ echo $OS_CLOUD my_cloud如果需要，重置变量：
$ export OS_CLOUD=my_other_cloud作为替代方案，您可以在每次运行
openstack命令时添加--os-cloud <cloud_name> 选项指定云名称。使用以下命令列出 DNS 服务数据库中的 denylists：
$ openstack zone blacklist list在上一步中获取的 denylist ID 时，使用
openstack zone blacklist show <denylist_ID> 命令显示特定 denylist 的属性。示例
$ openstack zone blacklist show 7622e241-8c3d-4c03-a692-8747e3cf2658
