在裸机集群中安装 OpenShift Container Platform 时，您可以使用机器（machine）和机器集（machineset）自定义资源（CR）为集群中存在的裸机主机置备和管理裸机节点。
13.1. 关于裸机主机和节点
要将 Red Hat Enterprise Linux CoreOS（RHCOS）裸机主机置备为集群中的节点，首先创建一个与裸机主机硬件对应的 MachineSet 自定义资源（CR）对象。裸机主机机器集描述了特定于您的配置的基础架构组件。将特定的 Kubernetes 标签应用于这些机器集，然后将基础架构组件更新为仅在那些机器上运行。
当您扩展包含 metal3.io/autoscale-to-hosts 注解的相关 MachineSet 时，Machine CR 会被自动创建。OpenShift Container Platform 使用 Machine CR 来置备与 MachineSet CR 中指定的主机对应的裸机节点。
