红帽全球峰会2.2. DNS 服务软件要求
Red Hat OpenStack Platform (RHOSP) DNS 服务（指定）取决于以下 RHOSP 核心组件：
- Identity 服务 (keystone)
- RabbitMQ
- MariaDB
- Redis
RHOSP 安装和配置工具集 director 会自动为 DNS 服务配置这些组件。
如果您使用 VLAN 或覆盖网络，希望 DNS 服务自动为其创建 DNS 记录，然后为这些网络设置一些网络分段 ID。DNS 服务不会为网络创建 DNS 记录，其分段 ID 不在网络服务(neutron) ml2_conf.ini 文件中指定的范围。
