使用多级映射时，来自.tfvars的Terraform值不加载

Question

当我试图使用带有.tfvar的多级地图时，我会在“地形图”上出现以下错误。我请求你帮我改正我的.tfvars

.tfvars

instance_config = {
  default = {
    test-vm1 = {
        instance_name  = "test-vm1"
        instance_image = "debian-cloud/debian-8"
        instance_type =  "n1-standard-4"
       },

    test-vm2 = {
        instance_name  = "test-vm2"
        instance_image = "debian-cloud/debian-9"
        instance_type =  "f1-micro"
       },

    test-vm3 = {
        instance_name  = "test-vm2"
        instance_image = "debian-cloud/debian-9"
        instance_type =  "f1-micro"
       }
  }
}

variable.tf

variable "instance_config" {

  type = map(object({
        instance_name  = string
        instance_image = string
        instance_type  = string
       }))
  
  default = {
    test-vm1 = {
        instance_name  = "test-vm1"
        instance_image = "debian-cloud/debian-8"
        instance_type =  "n1-standard-4"
       },

    test-vm2 = {
        instance_name  = "test-vm2"
        instance_image = "debian-cloud/debian-9"
        instance_type =  "f1-micro"
       }
  }
}

main.tf

resource "google_compute_instance" "vm_instance" {

  for_each     = var.instance_config

  name         = each.value.instance_name
  machine_type = each.value.instance_type
  tags         = var.instance_tags

  boot_disk {
    initialize_params {
      image = each.value.instance_image
    }
  }

  network_interface {
    network = var.gcp_network
  }
}

当我绘制地形图时，我看到了这个问题terraform plan -var-file=profiles/liverpool.tfvars

您不需要default在您的.tfvars。因此，应该是：

instance_config = {

    test-vm1 = {
        instance_name  = "test-vm1"
        instance_image = "debian-cloud/debian-8"
        instance_type =  "n1-standard-4"
       },

    test-vm2 = {
        instance_name  = "test-vm2"
        instance_image = "debian-cloud/debian-9"
        instance_type =  "f1-micro"
       },

    test-vm3 = {
        instance_name  = "test-vm2"
        instance_image = "debian-cloud/debian-9"
        instance_type =  "f1-micro"
       }

}
