红帽全球峰会4.4. 将浮动 IP 与 DNS 集成
网络服务(neutron)和 DNS 服务（指定）之间的集成可让您在创建浮动 IP 时自动添加 DNS 记录。
先决条件
- 您的云管理员为您提供了在创建启用了 DNS 的浮动 IP 时，需要使用所需的外部网络。
流程
提供您的凭据文件。
示例
$ source ~/overcloudrc利用云管理员提供的区域和外部网络，创建一个浮动 IP。
示例
在本例中，云用户在网络中创建一个带有 DNS 名称的浮动 IP
example-fip：$ openstack floating ip create --dns-name example-fip \ --dns-domain example.com. \ public
验证
确认您创建的浮动 IP 的 DNS 服务中存在 记录。
示例
在本例中，会查询 DNS 服务以获取
example.com.区域：$ openstack recordset list --type A example.com.输出示例
