使用 Bicep 管理 Azure Cosmos DB for Gremlin 资源

项目
09/14/2024

适用对象： Gremlin

本文介绍如何使用 Bicep 部署和管理 Azure Cosmos DB for Gremlin 帐户、数据库和图。

本文介绍 API for Gremlin 帐户的 Bicep 示例。你还可以查找 SQL、Cassandra、MongoDB 和表 API 的 Bicep 示例。

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，请将以下示例复制到新的 Bicep 文件中。可以选择创建一个要在使用不同名称和值部署同一资源的多个实例时使用的参数文件。可以通过多种方式部署 Azure 资源管理器模板，包括使用 Azure CLI 和 Azure PowerShell。
