我正在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"地形应用"时，结果是我所期望的。资源已创建。如果我将再次运行相同的配置，我将收到：错误：用于应用程序服务的名称"xxx"需要全局唯一且不可用：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，让我知道什么都没有更改，我缺少什么？我的提供者(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，我有地形.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"
}
附言：如果我试图通过添加connection_string部分或修改app_settings来修改应用程序服务配置，结果是相同的，抛出异常："错误：用于应用程序服务的名称"xxx"需要全局唯一且不可用：主机名"xxx"已存在。请选择其他名称。">

计划：1要添加，0要更改，0要销毁。
问题是您没有提供备份以使用azurerm，因此您的状态文件无法保存。要解决此问题，您可以在现有的.tf文件中添加backend，或者创建一个新的文件，例如backend.tf，内容为：
terraform {
backend "azurerm" {
}
}
