Question

尝试创建一个新的 Azure VM 并指定了创建空存储的选项 OS 高级磁盘，如下所示。不确定创建 100GB 空磁盘的有效选项是什么。

    resource "azurerm_virtual_machine" "main" {
      name                  = "${var.prefix}-vm"
      location              = "${azurerm_resource_group.main.location}"
      resource_group_name   = "${azurerm_resource_group.main.name}"
      network_interface_ids = ["${azurerm_network_interface.main.id}"]
      vm_size               = "Standard_D4s_v3"

      # Uncomment this line to delete the OS disk automatically when 
    deleting the VM
      # delete_os_disk_on_termination = true


      # Uncomment this line to delete the data disks automatically when 
    deleting the VM
      # delete_data_disks_on_termination = true

      storage_image_reference {
        publisher = "Canonical"
        offer     = "CentOS"
        sku       = "7.4"
        version   = "latest"
      }
      storage_os_disk {
        name              = "myosdisk1"
        caching           = "ReadWrite"
        create_option     = "Empty"
        managed_disk_type = "Premium_LRS"
        disk_size_gb      = "100"
      }
      os_profile {
        computer_name  = "hostname"
        admin_username = "testadmin"
        admin_password = "Password1234!"
      }
      os_profile_linux_config {
        disable_password_authentication = false
      }
      tags = {
        environment = "test-nonprod-provisioning"
      }
    }
