-   `disk_name` (string) - The value of disk name is blank by default. [2,
    128] English or Chinese characters, must begin with an
    uppercase/lowercase letter or Chinese character. Can contain numbers,
    ., _ and -. The disk name will appear on the console. It cannot
    begin with `http://` or `https://`.
    
-   `disk_category` (string) - Category of the system disk. Optional values
    are:
        -   cloud - general cloud disk
        -   cloud_efficiency - efficiency cloud disk
        -   cloud_ssd - cloud SSD
    
-   `disk_size` (int) - Size of the system disk, measured in GiB. Value
    range: [20, 500]. The specified value must be equal to or greater
    than max{20, ImageSize}. Default value: max{40, ImageSize}.
    
-   `disk_snapshot_id` (string) - Snapshots are used to create the data
    disk After this parameter is specified, Size is ignored. The actual
    size of the created disk is the size of the specified snapshot.
    
-   `disk_description` (string) - The value of disk description is blank by
    default. [2, 256] characters. The disk description will appear on the
    console. It cannot begin with `http://` or `https://`.
    
-   `disk_delete_with_instance` (bool) - Whether or not the disk is

-   `disk_encrypted` (boolean) - Whether or not to encrypt the data disk.
    If this option is set to true, the data disk will be encryped and corresponding snapshot in the target image will also be encrypted. By
    default, if this is an extra data disk, Packer will not encrypt the
    data disk. Otherwise, Packer will keep the encryption setting to what
    it was in the source image. Please refer to Introduction of ECS disk encryption
    for more details.
