4.9. 为 overcloud 置备裸机节点
要为 Red Hat OpenStack Platform (RHOSP)置备裸机节点，您可以定义您要部署和为这些节点部署并分配 overcloud 角色的裸机节点的数量和属性。您还定义节点的网络布局。您可以使用 YAML 格式在节点定义文件中添加所有这些信息。
置备过程会从节点定义文件创建一个 heat 环境文件。此 heat 环境文件包含您在节点定义文件中配置的节点规格，包括节点数、预测节点放置、自定义镜像和自定义 NIC。部署 overcloud 时，请将此 heat 环境文件包含在部署命令中。置备过程还会为每个节点定义的所有网络置备端口资源，或者在节点定义文件中角色。
注意
如果您使用预置备节点，您可以跳过置备裸机节点，并进入 部署启用了 spine-leaf 的 overcloud。
先决条件
-
访问
stack用户的 undercloud 主机和凭据。 - 裸机节点已注册、内省并可用于调配和部署。
流程
-
以
stack用户身份登录 undercloud 主机。 查找
stackrcundercloud 凭证文件：$ source ~/stackrc
创建裸机节点定义文件，如
spine-leaf-baremetal-nodes.yaml，并为您要置备的每个角色定义节点数。示例

使用
overcloud node provision命令置备 overcloud 裸机节点。示例
$ openstack overcloud node provision \ --stack spine_leaf_overcloud \ --network-config \ --output spine-leaf-baremetal-nodes-provisioned.yaml \ /home/stack/templates/spine-leaf-baremetal-nodes.yaml
重要您指定的输出文件的名称必须以
.yaml或.template结尾。在一个单独的终端中监控置备进度。当置备成功时，节点状态将从
available变为active：$ watch openstack baremetal node list
使用
metalsmith工具获取节点的统一视图，包括分配和端口：$ metalsmith list
- 请注意生成的输出文件的路径和文件名。部署 overcloud 时，需要此路径。
验证
确认节点与主机名关联：
$ openstack baremetal allocation list
后续步骤
