Creating Image Metadata (Native OpenStack API)

Function

This API is used to create image metadata.

After the API is successfully invoked, the image metadata is created, but the image file does not exist yet.

Huawei Cloud has stopped providing Windows images. This API will no longer be used to create Windows image metadata.

Request parameters

Parameter	Mandatory	Type	Description
__os_version	No	String	Specifies the image OS version. For the value range, see Values of Related Parameters. If this parameter is not specified, the value Other Linux(64 bit) will be used. In that case, the ECS creation using this image may fail, and the ECS created using this image may fail to run properly.
visibility	No	String	Specifies whether the image is available to other tenants. The default value is private. When creating image metadata, the value of visibility can be set to private only.
name	No	String	Specifies the image name. If this parameter is not specified, its value is empty by default. In that case, ECS creation using this image will fail. The name contains 1 to 255 characters. For detailed description, see Image Attributes. This parameter is left blank by default.
protected	No	Boolean	Specifies whether the image is protected. A protected image cannot be deleted. The default value is false.
container_format	No	String	Specifies the container format. The default value is bare.
disk_format	No	String	Specifies the image format. The value can be zvhd2, vhd, raw, iso, or qcow2. The default value is zvhd2 for a non-ISO image.
tags	No	Array of strings	Lists the image tags. The length is limited to 1 to 255 characters. By default, an image has no tags. NOTE: The tag is a key-value pair. Example: "tagkey=tagvalue"
min_ram	No	Integer	Specifies the minimum memory size (MB) required for running the image. The parameter value depends on ECS specifications. The default value is 0.
min_disk	No	Integer	Specifies the minimum disk space (GB) required for running the image. For Linux, the value ranges from 10 GB to 1,024 GB. For Windows, the value ranges from 20 GB to 1,024 GB. The value of this parameter must be greater than the image system disk capacity. Otherwise, the ECS creation may fail.

Response parameters

Parameter	Type	Description
visibility	String	Specifies whether the image is available to other tenants. The value is private.
name	String	Specifies the image name. If this parameter is not specified, its value is empty by default. In that case, ECS creation using this image will fail. The name contains 1 to 128 characters. For detailed description, see Image Attributes.
protected	Boolean	Specifies whether the image is protected. A protected image cannot be deleted. The value is false.
container_format	String	Specifies the container format. The value is bare.
disk_format	String	Specifies the image format. The value can be zvhd2, vhd, raw, iso, or qcow2. The default value is zvhd2 for a non-ISO image.
tags	Array of strings	Lists the image tags. The length is limited to 1 to 255 characters.
min_ram	Integer	Specifies the minimum memory size (MB) required for running the image. The parameter value depends on the ECS specifications limit. The value is generally set to 0.
min_disk	Integer	Specifies the minimum disk space (GB) required for running the image. It must be greater than the system disk capacity in the image. Otherwise, the ECS creation will fail. For Linux, the value ranges from 10 GB to 1,024 GB. For Windows, the value ranges from 20 GB to 1,024 GB.
status	String	Specifies the image status. The value can be one of the following: queued: indicates that the image metadata has already been created, and it is ready for the image file to upload. saving: indicates that the image file is being uploaded to the backend storage. deleted: indicates that the image has been deleted. killed: indicates that an error occurs on the image uploading. active: indicates that the image is available for use.
created_at	String	Specifies the time when the image was created. The value is in UTC format.
updated_at	String	Specifies the time when the image was updated. The value is in UTC format.
self	String	Specifies the image URL.
id	String	Specifies the image ID. After the image creation API is called, the image ID must be saved. The image ID is used to invoke the image uploading API and upload the image.
file	String	Specifies the URL for uploading and downloading the image file.
schema	String	Specifies the URL for accessing the schema.
__image_source_type	String	Specifies the image backend storage type. Only UDS is supported currently.
__image_size	String	Specifies the image size. The unit is byte.
__isregistered	String	Specifies whether the image is registered. Only registered images can be queried on the portal. The value is true.
__os_version	String	Specifies the image OS version. For the value range, see Values of Related Parameters.
__os_type	String	Specifies the image OS type. The value of this parameter depends on that of __os_version. The value can be Windows, Linux, or other.
__platform	String	Specifies the OS platform supported by the image. The value of this parameter depends on that of __os_version.
__os_bit	String	Specifies the OS bit. The value of this parameter depends on that of __os_version. The value can be 32 or 64.
__imagetype	String	Specifies the image type. private indicates a private image.
virtual_env_type	String	Specifies the platform type. Specifies the environment where the image is used. The value can be FusionCompute, Ironic, DataImage, or IsoImage. For an ECS image, the value is FusionCompute. For an ECS data disk image, the value is DataImage. For a BMS image, the value is Ironic. For an ISO image, the value is IsoImage.
owner	String	Specifies the ID of the project to which the image belongs.
__root_origin	String	Specifies that the image is created from an external image file. Value: file
checksum	String	Specifies the MD5 value of the image file.
size	Long	This parameter is unavailable currently.
virtual_size	Integer	Specifies the virtual size of the image. The unit is byte.
properties	Properties object	Specifies a collection of image attributes instead of a specified attribute.
