具有该 ID 的资源已存在 - 要通过 Terraform 管理此资源需要导入到状态中

Question

我通常不会问这样的问题，但是我觉得卡住了，我不想破解东西，而是花时间去理解。我是 terraform 的新手，正在尝试学习它，我为自己设定的一个简单任务是创建一个 SQL 服务器。

我的环境

我之前创建了一些资源组，每当我尝试使用相同的名称时，我都会收到错误消息。

 Error: A resource with the ID "/subscriptions/000000-0000-0000-0000-00000000005/resourceGroups/tf_learning" already exists - to be managed via Terraform this resource needs to be imported into the State. Please see the resource documentation for "azurerm_resource_group" for more information.

现在，你看看错误，经过 2 天的 google 研究，我按照这里的步骤操作。和 https://gmusumeci.medium.com/how-to-import-an-existing-azure-resource-in-terraform-6d585f93ea02 and Terraform resource with the ID already exists

我创建了一个名为 existing_statee.tf 的文件，内容如下。

resource "azurerm_resource_group" "tf_learning" {
}

运行

terraform import azurerm_resource_group.tf_learning /subscriptions/000000-0000-0000-0000-00000000005/resourceGroups/tf_learningterraform import azurerm_resource_group.tf_learning /subscriptions/000000-0000-0000-0000-00000000005/resourceGroups/tf_learning

我重新编辑了文件并保存了。

resource "azurerm_resource_group" "tf_learning" {
  # (resource arguments)
  name = "tf_learning"
  location = "UK South"
}

然后运行以下。

terraform init
terraform plan
terraform apply

令我惊讶的是，我仍然收到错误。

 Error: A resource with the ID "/subscriptions/00000-00000-0000-0000-00000000000/resourceGroups/tf_learning" already exists - to be managed via Terraform this resource needs to be imported into the State. Please see the resource documentation for "azurerm_resource_group" for more information.

我不知道下一步该怎么做，现在我会继续研究。

我想指出这一点，您在导入状态后existing_statee.tf中进行了配置

resource "azurerm_resource_group" "tf_learning" {
   name = "tf_learning"
   location = "UK South"
}

但是在main.tf你也重新定义

resource "azurerm_resource_group" "RG-Terraform" {
  name     = var.resource-group-name
  location = var.my_location
}
variable "resource-group-name" {
  default     = "tf_learning"
  description = "The prefix used for all resources in this example"
}
variable "my_location" {
  type = string
  default = "UK South"
}

由于您已经在 existing_statee.tf 中声明了此资源，也许您应该将其从 main.tf

中删除

具有该 ID 的资源已存在 - 要通过 Terraform 管理此资源需要导入到状态中

A resource with the ID already exists - to be managed via Terraform this resource needs to be imported into the State
