其他 - Terraform“用于App Service的名称“ xxx”必须是全局唯一的，并且不可用”

我在Terraform中应用以下配置：

resource "azurerm_resource_group" "rg" {
  name     = var.resourceGroupName
  location = var.location
}

resource "azurerm_app_service_plan" "app_plan" {
  name                = var.appServicePlanName
  location            = var.location
  resource_group_name = azurerm_resource_group.rg.name

  sku {
    tier = "Free"
    size = "F1"
  }
}

resource "azurerm_app_service" "app_service" {
  name                = var.appServiceName
  location            = var.location
  resource_group_name = azurerm_resource_group.rg.name
  app_service_plan_id = azurerm_app_service_plan.app_plan.id

  app_settings = {
    "SOME_KEY" = "some-value"
  }
}

我第一次运行“ terraform apply”，结果就是我所期望的。资源已创建。如果我将再次运行相同的配置，则会收到：错误：用于App Service的名称“ xxx”必须是全局唯一的，并且不可用：主机名“ xxx”已存在。请选择其他名称。

我有点困惑，因为我希望Terraform跳过任何更改，只是让我知道什么都没有更改，我想念什么？我的provider（provider.tf）配置如下：

provider "azurerm" {
  skip_provider_registration = "true"
  subscription_id = var.subscriptionId
  tenant_id       = var.tenantId
  client_id       = var.clientId
  client_secret   = var.clientSecret
}

此外，我有terraform.tfvars

resourceGroupName = "xxx-poc1-rg"
location = "eastus"
appServicePlanName = "xxx-poc1-asp01"
appServiceName = "xxx-poc1-apsvc01"
subscriptionId = ""
tenantId = ""
clientId = ""
clientSecret = ""

和variables.tf文件

variable "appServiceName" {
  type        = string
  description = "The name of app service"
}

variable "appServicePlanName" {
  type        = string
  description = "The name of app service plan"
}

variable "resourceGroupName" {
  type        = string
  description = "The name of resource group"
}

variable "location" {
  type        = string
  description = "Location"
}

variable "subscriptionId" {
  type        = string
  description = "Subscription id"
}

variable "tenantId" {
  type        = string
  description = "Tenant id"
}

variable "clientId" {
  type        = string
  description = "Client id"
}

variable "clientSecret" {
  type        = string
  description = "Client secret"
}

PS如果我尝试通过添加connection_string部分或修改app_settings来修改应用程序服务配置，则结果是一样的，但会抛出异常，提示“错误：用于应用程序服务的名称“ xxx”必须是全局唯一的，并且不是可用：主机名“ xxx”已存在。请选择其他名称。”

这是terraform状态的输出：D：\ alexus-git \ TerraformAppServicePlanTest [master≡]> terraform plan在计划之前刷新内存中的Terraform状态...刷新后的状态将用于计算此计划，但不会持久化到本地或远程状态存储。
