红帽全球峰会8.2. Compute 节点的自定义 NIC heat 模板
以下示例是 heat 模板，其中包含连接到外部 Red Hat Ceph Storage 集群的 overcloud 中 Compute 裸机节点的 NIC 配置。heat 模板中的配置将网络映射到以下网桥和接口：
| 网络 | Bridge | interface |
|---|---|---|
| Control Plane, Storage, Internal API | N/A |
|
| External, Tenant |
|
|
要在部署中使用以下模板，请将示例复制到 workstation 上的 custom_templates 目录中的 multiple_nics_vlans_dvr.j2。您可以为裸机节点的 NIC 配置修改此配置。
