使用 terraform 从映像导入资源并创建 VM

Question

我正在尝试导入资源并从 Azure 上的现有映像创建 VM。所有导入都成功，但是当我运行 terraform apply 时，出现以下错误： enter image description here

代码如下：

provider "azurerm" {
    version = "2.0.0"
    subscription_id = var.subscriptionID

    features {}
}
resource "azurerm_resource_group" "TerraformResourceGroup" {

}

resource "azurerm_network_security_group" "TerraformSecurityGroup" {

}

resource "azurerm_virtual_network" "TerraformVirtualNetwork" {

}

resource "azurerm_network_interface" "TerraformNetworkInterface" {

}

resource "azurerm_virtual_machine" "TerraformVM" {
  name                  = var.VM
  location              = var.location
  resource_group_name   = azurerm_resource_group.TerraformResourceGroup.name
  network_interface_ids = [azurerm_network_interface.TerraformNetworkInterface.id]
  vm_size               = "Standard_DS1_v2"

 storage_image_reference {
    id  = "/subscriptions/--/resourceGroups/TerraformResourceGroup/providers/Microsoft.Compute/images/TerraformVM-image-20210201164126"
}

  storage_os_disk {
    name              = "disk1"
    caching           = "ReadWrite"
    create_option     = "FromImage"
    managed_disk_type = "Standard_LRS"
    }

  os_profile {
    computer_name  = var.name
    admin_username = var.username
    admin_password = var.password
  }

  os_profile_windows_config {
     provision_vm_agent = true
  }

  tags = {
    environment = "staging"
  }
}

请帮忙

好吧，让我解释清楚一点。我创建了一个 rg 并使用 terraform 部署了一个 vm，然后捕获了该 VM。现在我需要在同一个 rg 中使用该图像部署一个 vm。我需要使用导入源还是数据源？如果我使用数据源，我得到以下信息：删除虚拟网络“xx”（资源组“yy”）时出错：network.VirtualNetworksClient#Delete：发送请求失败：StatusCode=400 -- 原始错误：Code="InUseSubnetCannotBeDeleted" Message="子网 xx 正在被 /subscriptions/--/resourceGroups/yy/providers/Microsoft.Network/networkInterfaces/xx/ipConfigurations/internal 使用，无法删除。要删除子网，请删除子网内的所有资源子网。 使用数据源的代码

    version = "2.0.0"
    subscription_id = var.subscriptionID

    features {}
}

  resource_group_name = data.azurerm_resource_group.TerraformResourceGroup.name

你能帮忙吗

Answer 1

根据错误消息，您在 azurerm_network_interface 中缺少参数。

您需要在resource "azurerm_network_interface"中添加location和resource_group_name：

这是一个例子：

    provider "azurerm" {
        version = "2.0.0"
        subscription_id = var.subscriptionID
    
        features {}
    }

    variable "prefix" {
         default = "tfvmex"
     }

    resource "azurerm_resource_group" "TerraformResourceGroup" {
      name     = "${var.prefix}-resources"
      location = "West US 2"
    }
   resource "azurerm_network_security_group" "TerraformSecurityGroup" {

   }
    
    resource "azurerm_virtual_network" "TerraformVirtualNetwork" {
      name                = "${var.prefix}-network"
      address_space       = ["10.0.0.0/16"]
      location            = azurerm_resource_group.main.location
      resource_group_name = azurerm_resource_group.main.name
    }
    
    resource "azurerm_network_interface" "TerraformNetworkInterface" {
      name                = "${var.prefix}-nic"
      location            = azurerm_resource_group.main.location
      resource_group_name = azurerm_resource_group.main.name
    

    }
    
    ......

更详细的信息，你可以参考这个关于Terraform azurerm_virtual_machine的文档。

Terraform import 命令不会生成 Terraform 资源配置。相反，它会将您现有的资源导入 Terraform 的状态。

将现有资源导入状态文件后。您需要参考状态提供的信息手动创建相应的资源配置文件，并使用 Terraform 管理您现有的基础设施。

例如，您可以运行terraform show，它提供来自状态或计划文件的人类可读输出。

然后你可以复制name和location的属性和内容来填充块

resource "azurerm_resource_group" "TerraformResourceGroup" {
    location = "westeurope"
    name     = "nancyexample-resources"
}

你可以用同样的方法填充剩余的方块。之后，您可以通过运行terraform plan 命令检查配置中的错误。 Terraform 计划向您显示如果您使用 terraform apply 命令应用配置将发生的更改。如果缺少或未设置任何参数，您可以修改配置文件以满足要求。

验证配置后，您可以运行terraform apply 来创建新资源。如需更多信息，请参阅Import Terraform configuration。
