Terraform を使用して Azure Cosmos DB for NoSQL のリソースを管理する

適用対象: NoSQL

この記事では、Terraform を使用して、Azure Cosmos DB アカウント、データベース、コンテナーのデプロイと管理を行う方法について説明します。

この記事では、NoSQL アカウントの Terraform サンプルを示します。

重要

  • アカウント名は、44 文字 (すべて小文字) に制限されています。
  • スループット (RU/秒) の値を変更するには、RU/秒を更新して Terraform ファイルを再デプロイします。
  • Azure Cosmos アカウントに対して場所の追加または削除を行う場合、他のプロパティを同時に変更することはできません。 これらの操作は個別に行う必要があります。
  • データベース単位でスループットをプロビジョニングし、すべてのコンテナー間で共有するには、データベースのオプションのプロパティにスループットの値を設定します。

以下のいずれかの Azure Cosmos DB リソースを作成するには、新しい Terraform ファイル (main.tf) にサンプルをコピーするか、リソース (main.tf) と変数 (variables.tf) 用に 2 つの個別のファイルを用意します。 AzureRM プロバイダーは、必ずメインの Terraform ファイルに含めるか、別のプロバイダー ファイルに分割してください。 すべてのサンプルは、Terraform サンプル リポジトリにあります。

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 {}
}

自動スケーリング スループットを備える Azure Cosmos アカウント

一貫性とフェールオーバーのためのオプションを備えた 2 つのリージョンで Azure Cosmos アカウントを作成します。データベースとコンテナーは、ほとんどのインデックス ポリシー オプションが有効になっている自動スケーリング スループット用に構成します。
