托管资源 "azurerm_network_interface" "myterraformnic" 尚未在 module.vm 中声明。蔚蓝

Question

我创建了两个模块：

网络 2.VM 在 network.tf 中，我为 azure 添加了网络配置，在 vm.tf 中，我正在尝试创建一个虚拟机。从 main.tf 调用两个模块时出现此错误：

关于 ..\modules\vm\vm.tf 第 20 行，在资源“azurerm_windows_virtual_machine”“myterraformvm”中： 20: network_interface_ids = [azurerm_network_interface.myterraformnic.id]

托管资源“azurerm_network_interface”“myterraformnic”尚未在 module.vm.
中声明

这是vm.tf

的代码

    # Resource Group
resource "azurerm_resource_group" "myterraformgroup" {
    name     = "myResourceGroup"
    location = "eastus"
}
resource "azurerm_image" "example" {
  # (resource arguments)
 
  name     = "WINDOWS2019C"
  location = "eastus"
  resource_group_name = azurerm_resource_group.myterraformgroup.name
}

# Virtual Machine Properties

resource "azurerm_windows_virtual_machine" "myterraformvm" {
    name                  = "myVM"
    location              = "eastus"
    resource_group_name   = azurerm_resource_group.myterraformgroup.name
    network_interface_ids = [azurerm_network_interface.myterraformnic.id]
    size                  = "Standard_DS1_v2"
    admin_username      = "XXXXXXXXXXXXX"
    admin_password      = "XXXXXXXXXXXXXX"

    os_disk {
        name              = "myOsDisk"
        caching           = "ReadWrite"
        storage_account_type = "Premium_LRS"
    }
    source_image_id = "/subscriptions/XXXXXXXXXXXXXXXXXXX/soft.Compute/images/XXXXXXXX"

这是network.tf

由于您在Network模块中定义了网络接口资源，您希望在另一个模块VM中调用网络接口。您需要声明网络模块（子模块）的输出值，以选择性地导出某些值以供调用模块访问。

在这种情况下，

main.tf

module "network" {
    source = "../modules/network"
   
}
module "vm" {
    source = "../modules/vm"
    vm_nic = module.network.nic
}

vm.tf

...

variable "vm_nic" {}  # this variables.tf should be in the same directory as the vm.tf
...
resource "azurerm_windows_virtual_machine" "myterraformvm" {
    name                  = "myVM"
    location              = "eastus"
    resource_group_name   = azurerm_resource_group.myterraformgroup.name
    network_interface_ids = [var.vm_nic]   # change this

network.tf

output "nic" {
    value = azurerm_network_interface.myterraformnic.id
}
