google-cloud-platform - 即使资源存在，将 gcp 资源导入 terraform 也会失败

Question

我正在尝试使用 terraform import 命令导入现有的 gcp 计算实例。但是我遇到了这个错误，它说在使用导入命令时资源不存在:

 terraform import google_compute_instance.tf-instance-2 my_project_id

google_compute_instance.tf-instance-2: Import prepared!
  Prepared google_compute_instance for import
google_compute_instance.tf-instance-2: Refreshing state... [id=projects/qwiklabs-gcp-02-67a8ccc33dba/zones/us-central1-a/instances/qwiklabs-gcp-02-67a8ccc33dba]
╷
│ Error: Cannot import non-existent remote object
│
│ While attempting to import an existing object to "google_compute_instance.tf-instance-2", the provider detected that no object exists with the given id. Only pre-existing objects can be imported; check that the id is correct and that it is
│ associated with the provider's configured region or endpoint, or use "terraform apply" to create a new remote object for this resource.
╵

但是当我列出可用的 gcloud 计算实例时，tf-instance-2(我尝试导入的实例)就在那里。

我尝试导入的实例是由 GCP 的代码实验室自动创建的。我的 main.tf 仅包含 3 个 block ，terraform、google provider 和 google_compute_instance 资源。我尝试过的事情:

• 更改 terraform 和 google provider 的版本
• terraform init 和 terraform init -refconfigure 在运行导入命令之前。
• 确保 are 实例的所有属性都在 terraform 中。

main.tf 文件:

terraform {
  required_providers {
    google = {
      source  = "hashicorp/google"
      version = "4.8.0"
    }
  }
}

provider "google" {
  project = var.project_id
  region  = var.region
  zone    = var.zone
}

resource "google_compute_instance" "tf-instance-2" {
  name = "tf-instance-2"
  #   id = "4193295884192005746"
  project      = var.project_id
  zone         = var.zone
  machine_type = "n1-standard-1"
  labels = {
    "goog-dm" = "qldm-10079641-937281f7192921b3"
  }
  boot_disk {
    initialize_params {
      image = "debian-10-buster-v20220118"
    }
  }
  network_interface {
    network = "default"
    access_config {

    }
  }
  allow_stopping_for_update = true
  metadata_startup_script   = <<-EOT
        #!/bin/bash
    EOT
}

根据 google_compute_instance 的import 文档:

Instances can be imported using any of these accepted formats:

$ terraform import google_compute_instance.default projects/{{project}}/zones/{{zone}}/instances/{{name}}
$ terraform import google_compute_instance.default {{project}}/{{zone}}/{{name}}
$ terraform import google_compute_instance.default {{name}}

name 在这里可能是最简单的，因此我们可以修改 import 命令以相应地定位它:

terraform import google_compute_instance.tf-instance-2 tf-instance-2
