在 Azure 中创建 VM 时出现错误 PropertyChangeNotAllowed

Question

我正在尝试使用以下配置在 Azure 中创建 VM。

resource “azurerm_virtual_machine” “VM38” {
    name = “VM38”
    resource_group_name = data.azurerm_resource_group.myRG.name
    location = data.azurerm_resource_group.myRG.location
    vm_size = “Standard_F16s_v2”
    delete_os_disk_on_termination = true
    delete_data_disks_on_termination = true
    
    os_profile {
        computer_name = “vm38”
        admin_username = “adminuser”
        admin_password = “Password1234!”
        custom_data = base64encode(data.cloudinit_config.hybrid_vm38_cloudinit_cfg.rendered)
    }
    
    os_profile_linux_config {
        disable_password_authentication = false
    }
    
    storage_image_reference {
        id = data.azurerm_image.my_image.id
    }
    
    depends_on = [aws_instance.vm12]
    
    storage_os_disk {
        name = “VMDisk”
        create_option = “FromImage”
        caching = “ReadWrite”
        #disk_size_gb = 16
        #os_type = “Linux”
        #managed_disk_type = “Standard_LRS”
        vhd_uri = var.vmVHDURI
    }
    
    network_interface_ids = [azurerm_network_interface.mgmtNwIntf.id, azurerm_network_interface.transportNwIntf.id]
}

当我执行 terraform apply 时，我遇到了错误……

错误：compute.VirtualMachinesClient#CreateOrUpdate：发送请求失败：StatusCode=0 – 原始错误：autorest/azure：服务返回错误。 Status= Code=“PropertyChangeNotAllowed” Message=“不允许更改属性‘osDisk.name’。”目标=“osDisk.name”

使用 azurerm_virtual_machine.VM38， 在 az_virtual_machine.tf 第 1 行，资源“azurerm_virtual_machine”“VM38”中： 1：资源“azurerm_virtual_machine”“VM38”{

请告诉我如何解决此问题。

Terraform 和 Azure 提供程序版本详细信息如下： Terraform v1.0.8 在 linux_amd64 上

创建 VM 时不能更改 os_disk 名称。它应该是 "osdisk" 或以它开头的东西。

我使用以下代码进行了测试：

provider "azurerm" {
  features {}
}

resource "azurerm_resource_group" "example" {
  name     = "ansuman-resources"
  location = "West US 2"
}

resource "azurerm_virtual_network" "example" {
  name                = "ansuman-network"
  address_space       = ["10.0.0.0/16"]
  location            = "${azurerm_resource_group.example.location}"
  resource_group_name = "${azurerm_resource_group.example.name}"
}

resource "azurerm_subnet" "example" {
  name                 = "internal"
  resource_group_name  = "${azurerm_resource_group.example.name}"
  virtual_network_name = "${azurerm_virtual_network.example.name}"
  address_prefixes     = ["10.0.2.0/24"]
}

resource "azurerm_network_interface" "example" {
  name                = "ansuman-nic"
  location            = "${azurerm_resource_group.example.location}"
  resource_group_name = "${azurerm_resource_group.example.name}"

  ip_configuration {
    name                          = "testconfiguration1"
    subnet_id                     = "${azurerm_subnet.example.id}"
    private_ip_address_allocation = "Dynamic"
  }
}

# we assume that this Custom Image already exists
data "azurerm_image" "custom" {
  name                = "ansumantestvm-image-20211007225625"
  resource_group_name = "resourcegroup"
}

resource "azurerm_virtual_machine" "example" {
  name                  = "ansuman-vm"
  location              = "${azurerm_resource_group.example.location}"
  resource_group_name   = "${azurerm_resource_group.example.name}"
  network_interface_ids = ["${azurerm_network_interface.example.id}"]
  vm_size               = "Standard_F2"

  # This means the OS Disk will be deleted when Terraform destroys the Virtual Machine
  # NOTE: This may not be optimal in all cases.
  delete_os_disk_on_termination = true

  storage_image_reference {
    id = "${data.azurerm_image.custom.id}"
  }

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

  os_profile {
    computer_name  = "hostname"
    admin_username = "testadmin"
    admin_password = "Password1234!"
  }
  os_profile_windows_config {
  }
}

输出：

注意：请确保在从原始VM创建映像时，首先对其进行泛化。如果它没有被通用化，那么从自定义镜像创建的虚拟机将卡在创建状态并且无法启动。

如果您想将 osdisk 名称更改为您选择的名称，那么作为一种解决方案，尝试首先使用 create option "copy" or "import" 从映像创建托管 os 磁盘，然后在创建 VM 时附加磁盘，就像从自定义映像创建托管磁盘一样也不支持，只能为平台图像或市场图像完成。你可以参考这个GitHub issue和这个Github issue。

参考 terraform 代码以解决类似问题，以便为从平台图像/市场图像创建的 osdisk 提供自定义名称，Charles Xu 已在此 SO thread 中完成。
