使用 Azure 资源管理器模板管理 Azure Cosmos DB for MongoDB 资源
适用对象：
MongoDB
本文介绍如何使用 Azure 资源管理器模板来帮助部署和管理适用于 API for MongoDB 的 Azure Cosmos DB 帐户、数据库和集合。
本文仅提供 Azure Cosmos DB API for MongoDB 的示例，若要查找其他 API 类型帐户的示例，请参阅以下文章：将 Azure 资源管理器模板与适用于 Cassandra、Gremlin、SQL、表的 Azure Cosmos DB API 配合使用。
重要
- 帐户名称限制为 44 个字符，全部小写。
- 若要更改吞吐量值，请用更新的 RU/s 重新部署模板。
- 当你在 Azure Cosmos DB 帐户中添加或删除位置时，无法同时修改其他属性。 必须单独执行这些操作。
若要创建以下任何 Azure Cosmos DB 资源，请将下列示例模板复制到新的 json 文件中。 在部署具有不同名称和值的同一资源的多个实例时，可以选择创建要使用的参数 json 文件。 可以通过多种方式部署 Azure 资源管理器模板，包括 Azure 门户、Azure CLI、Azure PowerShell 和 GitHub。
预配了自动缩放吞吐量的 Azure Cosmos DB for MongoDB 帐户
此模板会创建 MongoDB API（3.2、3.6、4.0 和 4.2）的 Azure Cosmos DB 帐户，其中包含两个在数据库级别共享自动缩放吞吐量的集合。 此模板还支持从 Azure 快速入门模板库进行一键部署。
