Управление ресурсами Azure Cosmos DB для NoSQL с помощью terraform

Статья
10/18/2023

ОБЛАСТЬ ПРИМЕНЕНИЯ: NoSQL

В этой статье вы узнаете, как использовать terraform для развертывания учетных записей, баз данных и контейнеров Azure Cosmos DB и управления ими.

В этой статье показаны примеры terraform для учетных записей NoSQL.

Важно!

Длина имен учетных записей ограничена 44 символами (только строчные буквы).
Чтобы изменить значения пропускной способности (ЕЗ/с), повторно разверните terraform-файл с обновленным ЕЗ/с.
Одновременно с добавлением или удалением расположений в учетной записи Azure Cosmos нельзя изменять другие свойства. Эти операции должны выполняться отдельно.
Чтобы подготовить пропускную способность на уровне базы данных и предоставить ее всем контейнерам, примените значения пропускной способности к свойству параметров базы данных.

Чтобы создать любой из ресурсов Azure Cosmos DB ниже, скопируйте пример в новый terraform-файл (main.tf) или у вас есть два отдельных файла для ресурсов (main.tf) и переменных (variables.tf). Не забудьте включить поставщик azurerm в основной terraform-файл или разделить на отдельный файл поставщиков. Все примеры можно найти в репозитории примеров terraform.

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 {}
}

Учетная запись Azure Cosmos c автомасштабированием пропускной способности

Этот шаблон используется для создания учетной записи Azure Cosmos в двух регионах с заданными параметрами для согласованности и отработки отказа. При этом база данных и контейнер настроены для автомасштабирования пропускной способности, вследствие чего большинство параметров политики индексирования включено.
