Administración de recursos de Azure Cosmos DB for NoSQL mediante Terraform

Artículo
10/25/2023

SE APLICA A: NoSQL

En este artículo, aprenderá a usar Terraform para implementar y administrar cuentas, bases de datos y contenedores de Azure Cosmos DB.

En este artículo se muestran ejemplos de Terraform para cuentas NoSQL.

Importante

Los nombres de cuenta están limitados a 44 caracteres, todo en minúsculas.
Para cambiar los valores de rendimiento (RU/s), vuelva a implementar el archivo de Terraform con las RU/s actualizadas.
Cuando agrega o elimina ubicaciones en una cuenta de Azure Cosmos, no puede modificar otras propiedades simultáneamente. Estas operaciones se deben realizar por separado.
Para aprovisionar el rendimiento en el nivel de base de datos y compartirlo entre todos los contenedores, aplique los valores de rendimiento a la propiedad de opciones de base de datos.

Para crear cualquiera de los siguientes recursos de Azure Cosmos DB, copie el ejemplo en un nuevo archivo de Terraform (main.tf) o, alternativamente, disponga dos archivos independientes para los recursos (main.tf) y las variables (variables.tf). Asegúrese de que incluye el proveedor azurerm en el archivo "main" de Terraform o lo separa en un archivo de proveedores independiente. Todos los ejemplos se pueden encontrar en el repositorio de ejemplos de 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 {}
}
