Properties

Name Type Required Editable Description Validity
Description String No No The description of the image. The description can be up to 256 characters in length. Default value: null. The description cannot start with http:// or https://.
InstanceId String No No The ID of the ECS instance used to create the image. For more information about how to use an instance to create an image, see Create a custom image by using an instance.
ImageName String No No The name of the image. The name must be 2 to 128 characters in length and can contain letters, digits, underscores (_), and hyphens(-). It must start with a letter and cannot start with http:// or https://.
SnapshotId String No No The ID of the snapshot used to create the image.
  • If both this parameter and InstanceId are set, this parameter does not take effect. In this case, the system will use an instance to create a custom image.
Tag List No No The tags of the image. None
ResourceGroupId String No No The ID of the resource group to which the custom image will belong. None
Platform String No No When you specify a data disk snapshot to be used to create the system disk of the custom image, you must use the Platform parameter to determine the release version of the operating system for the system disk. None
DiskDeviceMapping List No No The list of mappings between images and snapshots. None
Architecture String No No When you specify a data disk snapshot to be used to create the system disk of the custom image, you must use the Architecture parameter to determine the architecture of the system disk. Default value: x86_64. Valid values:
  • i386
  • x86_64

DiskDeviceMapping

"DiskDeviceMapping": [
  {
    "Device": String,
    "SnapshotId": String,
    "Size": Integer,
    "DiskType": String
  }
]

DiskDeviceMapping properties

Name Type Required Editable Description Validity
Device String No No The device name of a disk in the custom image. The system allocates a device name in the alphabetical order from /dev/xvda to /dev/xvdz by default.
SnapshotId String No No The ID of the snapshot that is used to create the custom image. None
Size Integer No No

The size of a disk in the custom image. Unit: GiB.
Valid values: 5 to 2000
  • The default value is the size of the snapshot specified by the DiskDeviceMapping.N.SnapshotId parameter.
  • If the DiskDeviceMapping.N.SnapshotId parameter is not set, the disk size is 5 GiB.
  • The disk size must be greater than or equal to the size of the snapshot specified by the DiskDeviceMapping.N.SnapshotId parameter.
DiskType String No No The type of a disk in the custom image. You can set this parameter to create the system disk of the custom image from a data disk snapshot. If you do not set this parameter, the disk type is determined by the corresponding snapshot.

Valid values:

  • system: indicates a system disk.
  • data: indicates a data disk.

Response parameters

Fn::GetAtt

ImageId: the ID of the custom image.
