利用维护控制，可以决定何时将自动 OS 映像升级应用到虚拟机规模集。 若要了解如何使用维护控制，请参阅 Azure 虚拟机规模集的维护控制。
本文介绍如何使用 Azure 资源管理器 (ARM) 模板创建维护配置。 将了解如何执行以下操作：
- 创建配置
- 将配置分配给虚拟机
Azure 资源管理器模板是定义项目基础结构和配置的 JavaScript 对象表示法 (JSON) 文件。 模板使用声明性语法。 你可以在不编写用于创建部署的编程命令序列的情况下，描述预期部署。
创建配置
创建配置时，请务必注意存在不同范围，各范围对应的创建模板中都具有唯一属性。 请确保使用正确的范围。
有关此维护配置模板的详细信息，请参阅 maintenanceConfigurations。
