Terraform 从 Packer 中制作的托管磁盘映像创建 VM

【中文标题】Terraform 从 Packer 中制作的托管磁盘映像创建 VM

【英文标题】：Terraform creating VM from managed disk image made in Packer

【发布时间】：2018-06-13 06:24:16

【问题描述】：

我已经使用 Packer 创建了一个自定义 VM 映像，现在我正在尝试使用 Terraform 基于此映像创建一个新 VM，但我对如何设置我的 .TF 文件感到困惑。我可以创建其余的基础设施。

我认为我的打包程序 json 文件创建了一个托管磁盘映像，但我不确定如何设置它并且无法在线找到示例。

我对基础设施即代码和 Azure ecco 系统很陌生

main.tf

    resource "azurerm_managed_disk" "managedDisk" 
  name                 = "managed_disk_test1"
  location             = "northeurope"
  resource_group_name  = "$azurerm_resource_group.packer.name"
  storage_account_type = "Standard_LRS"
  create_option        = "FromImage"
  image_reference_id   = "/subscriptions/33efe2dc-e7a0-4fb8-827d-8be939879420/resourceGroups/packerRG/providers/Microsoft.Compute/images/myPackerImage"
  disk_size_gb         = "1"



resource "azurerm_virtual_machine" "PackerVm_TEST" 
    name =  "$var.hostname"
    location = "northeurope"
    resource_group_name   = "$azurerm_resource_group.packer.name"
network_interface_ids = ["$azurerm_network_interface.packerNetInt_Test.id"]
    vm_size = "Standard_D2s_v3"


    storage_os_disk 
        name            = "FromPackerImageOsDisk"
        managed_disk_type = "Standard_LRS"
        caching           = "ReadWrite"
        create_option     = "FromImage"
    

        os_profile 
            computer_name  = "PackerVmTEST"
            admin_username = "packermakeradmin1"
            admin_password = "RMKRTest123"
          
            os_profile_windows_config 
                enable_automatic_upgrades = "true"
                provision_vm_agent ="true"
            

packer.json

      "& $Env:SystemRoot\\System32\\Sysprep\\Sysprep.exe /oobe /generalize /shutdown /quiet"
    ]
  ]

运行 terraform apply 时的输出

* azurerm_virtual_machine.PackerVm_TEST: compute.VirtualMachinesClient#CreateOrUpdate: Failure responding to request: StatusCode=400 -- Original Error: autorest/azure: Service returned an error. Status=400 Code="InvalidParameter" Message="Cannot specify user ima

【参考方案1】：

有两种方法可以将托管磁盘附加到 VM。

要么删除 azure_managed_disk 资源，要么在 azurerm_virtual_machine 资源中指定映像引用。托管磁盘将自动创建并附加到 VM。

resource "azurerm_virtual_machine" "PackerVm_TEST" 
name =  "$var.hostname"
location = "northeurope"
resource_group_name   = "$azurerm_resource_group.packer.name"
network_interface_ids = ["$azurerm_network_interface.packerNetInt_Test.id"]
vm_size = "Standard_D2s_v3"

storage_os_disk 
    name            = "FromPackerImageOsDisk"
    managed_disk_type = "Standard_LRS"
    caching           = "ReadWrite"
    create_option     = "FromImage"

storage_image_reference 
    id = "/subscriptions/33efe2dc-e7a0-4fb8-827d-8be939879420/resourceGroups/packerRG/providers/Microsoft.Compute/images/myPackerImage"


os_profile 
    computer_name  = "PackerVmTEST"
    admin_username = "packermakeradmin1"
    admin_password = "RMKRTest123"
  
os_profile_windows_config 
    enable_automatic_upgrades = "true"
    provision_vm_agent ="true"

或者您在 azurerm_virtual_machine 资源中添加托管磁盘 ID。

resource "azurerm_managed_disk" "managedDisk" 
  name                 = "managed_disk_test1"
  location             = "northeurope"
  resource_group_name  = "$azurerm_resource_group.packer.name"
  storage_account_type = "Standard_LRS"
  create_option        = "FromImage"
  image_reference_id   = "/subscriptions/33efe2dc-e7a0-4fb8-827d-8be939879420/resourceGroups/packerRG/providers/Microsoft.Compute/images/myPackerImage"
  disk_size_gb         = "1"


resource "azurerm_virtual_machine" "PackerVm_TEST" 
    name =  "$var.hostname"
    location = "northeurope"
    resource_group_name   = "$azurerm_resource_group.packer.name"
    network_interface_ids = ["$azurerm_network_interface.packerNetInt_Test.id"]
    vm_size = "Standard_D2s_v3"

    storage_os_disk 
        name            = "FromPackerImageOsDisk"
        managed_disk_id = "$azurerm_managed_disk.managedDisk.id"
        managed_disk_type = "Standard_LRS"
        caching           = "ReadWrite"
        create_option     = "Attach"
    
    os_profile 
        computer_name  = "PackerVmTEST"
        admin_username = "packermakeradmin1"
        admin_password = "RMKRTest123"
      
    os_profile_windows_config 
        enable_automatic_upgrades = "true"
        provision_vm_agent ="true"
    

来自 terraform 文档

managed_disk_id - （可选）指定一个现有的托管磁盘以按 id 使用。只能在 create_option 为 Attach 时使用。

【讨论】：

不幸的是，这种语法实际上不起作用。您目前不能引用除平台/市场图像之外的任何内容：github.com/terraform-providers/terraform-provider-azurerm/…

【参考方案2】：

我在 .TF 文件中添加了以下代码，它工作正常。感谢您的帮助！

storage_image_reference 
    id = "/subscriptions/33efe2dc-e7a0-4fb8-827d-8be939879420/resourceGroups/packerRG/providers/Microsoft.Compute/images/myPackerImage"
