用Terraform部署Azure Event Hubs，报api-version不支持（Mitigate方法）

用Terraform部署Azure Event Hubs报以下错：

 

 Error: creating Namespace: (Name "mcpredimacn2cehubns" / Resource Group "rg_test20210707"): performing CreateOrUpdate: namespaces.NamespacesClient#CreateOrUpdate: Failure sending request: StatusCode=0 -- Original Error: Code="NoRegisteredProviderFound" Message="No registered resource provider found for location 'chinanorth2' and API version '2021-01-01-preview' for type 'namespaces'. The supported api-versions are '2014-09-01, 2015-08-01, 2017-04-01, 2018-01-01-preview'. The supported locations are 'chinanorth, chinaeast, chinanorth2, chinaeast2'."

主要原因是未指定hashicorp/azurerm的Version，默认用了最新版（07/08/2021时，是2.66.0）。

用以下方式指定老版本，就可以了：

terraform {
  required_providers {
    azurerm = {
      source = "hashicorp/azurerm"
      version = "=2.0.0"
    }
  }
}
provider "azurerm" {
  features {}
}

 

 

Azure上运行Terraform的方式，可以参考以下文档：

https://docs.azure.cn/zh-cn/governance/policy/assign-policy-terraform
https://docs.microsoft.com/en-us/azure/developer/terraform/get-started-powershell

有关此文的完整Terraform脚本是：

terraform {
  required_providers {
    azurerm = {
      source = "hashicorp/azurerm"
      version = "=2.0.0"
    }
  }
}
provider "azurerm" {
  features {}
}

variable "DEPLOYMENT" {
  type    = map(string)
  default = {
      env = "mc"
      MC_region = "cn2"
  }
}

  name                = "${var.DEPLOYMENT.env}test${var.DEPLOYMENT.MC_region}cehubns"
  location            = azurerm_resource_group.rg-test.location
  resource_group_name = azurerm_resource_group.rg-test.name

                var.DEPLOYMENT)}"

}

resource "azurerm_eventhub" "test" {
  name                = "${var.DEPLOYMENT.env}test${var.DEPLOYMENT.MC_region}cehub"
  namespace_name      = azurerm_eventhub_namespace.testeventhubns.name
