不正确的 terraform 配置 post 0.12upgrade 命令

Question

以最简单的形式， main.tf如下：

data "azurerm_resource_group" "tf-rg-external" {

  vm_size               = var.vm_size

  delete_os_disk_on_termination = true

  delete_data_disks_on_termination = true

  storage_image_reference {
    publisher = var.vm_publisher
    offer     = var.vm_offer
    sku       = var.vm_sku
    version   = var.vm_img_version
  }

  storage_os_disk {
    name              = "${var.base_hostname}${format("%02d", count.index + 1)}-wosdsk01"
    caching           = var.caching_option

  }


  os_profile_windows_config {
    enable_automatic_upgrades = false
    provision_vm_agent        = "true"
  }
}

variables.tf如下：

# Declare env variable
variable "rg_name" {
  type = string
}

variable "vnet_name" {
  type = string
}

variable "subnet_name" {
  type = string
}

variable "app_nsg" {

}

  type = number
}

variable "base_hostname" {

}

variable "sto_acc_suffix" {
  type = string
}

variable "sto_acc_tier_std" {
  type    = string
  default = "Standard"
}

variable "sto_acc_rep_type_lrs" {
  type    = string
  default = "LRS"
}

variable "vm_size" {
  type = string
}

variable "vm_publisher" {
  type = string
}

variable "vm_offer" {
  type = string
}

variable "vm_sku" {
  type = string
}

variable "vm_img_version" {
  type = string
}

variable "username" {
  type = string
}

variable "password" {
  type = string
}

variable "caching_option" {
  type    = string
  default = "ReadWrite"
}

variable "create_option" {
  type    = string
  default = "FromImage"
}

variable "managed_disk_std_lrs" {
  type    = string
  default = "Standard_LRS"
}

variable "managed_disk_prem_lrs" {
  type    = string
  default = "Premium_LRS"
}

variable "allowed_source_ips" {
  description = "List of ips from which inbound connection to VMs is allowed"
  type        = list(string)
}

我运行下面的命令用于将 terraform 配置升级到 0.12 及更高版本

terraform 0.12upgrade

错误：

Error: Syntax error in configuration file

  on main.tf line 22, in data "azurerm_resource_group" "tf-rg-external":
  22:   name = var.rg_name

Error while parsing: At 22:10: Unknown token: 22:10 IDENT var.rg_name


Error: Syntax error in configuration file

  on variable.tf line 3, in variable "rg_name":
   3:   type = string

Error while parsing: At 3:10: Unknown token: 3:10 IDENT string

知道了，问题是什么？如果我不使用运行 terrafom 0.12upgrade 命令，这将起作用。我很感兴趣为什么它不起作用。我在另一个 terraform 配置中执行了相同的升级命令，但我在那里遇到了类似的错误。

一次观察。此 IDENT 错误来自 main.tf 和 variable.tf 文件中的第一个变量。无法关联此错误。

您已经在使用 0.12 语法，0.12upgrade 命令期望找到 0.11 语法并将尝试自动更新它。

例如name = var.rg_name - 注意缺少 ${}

见https://www.terraform.io/docs/commands/0.12upgrade.html

The terraform 0.12upgrade command applies several automatic upgrade rules to help prepare a module that was written for Terraform v0.11 to be used with Terraform v0.12.
