3.2.2. 清单示例
以下示例 YAML 文件使用 nodePlacement、affinity（关联性） 和 tolerations（容限）对象为 OpenShift Virtualization 组件自定义节点放置。
3.2.2.1. Operator Lifecycle Manager Subscription 对象
3.2.2.1.1. 示例：在 OLM 订阅对象中使用 nodeSelector 的节点放置
在本例中，配置了 nodeSelector，OLM 将 OpenShift Virtualization Operator 放置到标记为 example.io/example-infra-key = example-infra-value 的节点上。

在本例中，为 OLM 部署 OpenShift Virtualization Operator 保留的节点使用 key=virtualization:NoSchedule 污点标记。只有具有与容限匹配的 pod 才会调度到这些节点。
