使用 terraform 管理 Azure Cosmos DB for NoSQL 资源

Artículo
01/08/2024

适用范围： NoSQL

本文介绍如何使用 terraform 部署和管理 Azure Cosmos DB 帐户、数据库和容器。

本文介绍 NoSQL 帐户的 terraform 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（RU/秒）值，请使用更新的 RU/秒值重新部署 Terraform 文件。
当你在 Azure Cosmos 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。
若要在数据库级别预配吞吐量并跨所有容器进行共享，请将吞吐量值应用于数据库选项属性。

若要创建以下任意 Azure Cosmos DB 资源，请将示例复制到新的 Terraform 文件 (main.tf) 中，或者为资源 (main.tf) 和变量 (variables.tf) 提供两个单独的文件。请务必在主 terraform 文件中包括 azurerm 提供程序，或拆分为单独的提供程序文件。所有示例都可以在 terraform 示例存储库中找到。

terraform {
  required_version = ">= 1.0"

  required_providers {
    azurerm = {
      source  = "hashicorp/azurerm"
      version = ">= 3.0, < 4.0"
    }
    random = {
      source  = "hashicorp/random"
      version = ">= 3.0"
    }
  }
}

provider "azurerm" {
  features {}
}

具有自动缩放吞吐量的 Azure Cosmos 帐户

在两个区域中创建一个 Azure Cosmos 帐户，其中包含用于一致性和故障转移的选项，以及为启用了大多数索引策略选项的自动缩放吞吐量配置的数据库和容器。
