红帽全球峰会3.3. 使用 OVN 部署内部 DNS
要在本地网络上为 east-west 流量使用域名而不是 IP 地址，请使用内部域名服务(DNS)。使用内部 DNS，ovn-controller 在计算节点上本地响应 DNS 查询。请注意，内部 DNS 覆盖实例 /etc/resolv.conf 文件中指定的任何自定义 DNS 服务器。部署内部 DNS 时，实例的 DNS 查询由 ovn-controller 处理，而不是自定义 DNS 服务器。
流程
使用
NeutronPluginExtensions参数启用 DNS：parameter_defaults: NeutronPluginExtensions: "dns"在部署 overcloud 前设置 DNS 域：
NeutronDnsDomain: "mydns-example.org"部署 overcloud：
$ openstack overcloud deploy \ --templates /usr/share/openstack-tripleo-heat-templates \ ... -e /usr/share/openstack-tripleo-heat-templates/environments/services-docker/neutron-ovn-dvr-ha.yaml
