6.5.1. Request¶

Name	In	Type	Description
`Content-Type`	header	string	The media type descriptor for the request body. Use `application/openstack-images-v2.1-json-patch`. (You can also use `application/openstack-images-v2.0-json-patch`, but keep in mind that it’s deprecated.)
`image_id`	path	string	The UUID of the image.

6.5.1.1. Example¶

6.5.2. Response¶

Name	In	Type	Description
`checksum`	body	string	Hash that is used over the image data. The Image service uses this value for verification. The value might be `null` (JSON null data type).
`container_format`	body	enum	Format of the image container. Values may vary based on the configuration available in a particular OpenStack cloud. Example formats are: `ami`, `ari`, `aki`, `bare`, `ovf`, `ova`, or `docker`. The value might be `null` (JSON null data type).
`created_at`	body	string	The date and time when the resource was created. The date and time stamp format is ISO 8601: CCYY-MM-DDThh:mm:ss±hh:mm For example, `2015-08-27T09:49:58-05:00`. The `±hh:mm` value, if included, is the time zone as an offset from UTC.
`disk_format`	body	enum	The format of the disk. Values may vary based on the configuration available in a particular OpenStack cloud. See the Image Schema response from the cloud itself for the valid values available. Example formats are: `ami`, `ari`, `aki`, `vhd`, `vhdx`, `vmdk`, `raw`, `qcow2`, `vdi`, `ploop` or `iso`. The value might be `null` (JSON null data type).
`file`	body	string	The URL for the virtual machine image file.
`id`	body	string	A unique, user-defined image UUID, in the format: nnnnnnnn-nnnn-nnnn-nnnn-nnnnnnnnnnnn Where n is a hexadecimal digit from 0 to f, or F. For example: b2173dd3-7ad6-4362-baa6-a68bce3565cb If you omit this value, the API generates a UUID for the image.
`min_disk`	body	integer	Amount of disk space in GB that is required to boot the image. The value might be `null` (JSON null data type).
`min_ram`	body	integer	Amount of RAM in MB that is required to boot the image. The value might be `null` (JSON null data type).
`name`	body	string	The name of the image. Value might be `null` (JSON null data type).
`owner`	body	string	An identifier for the owner of the image, usually the project (also called the “tenant”) ID. The value might be `null` (JSON null data type).
`os_hash_algo`	body	string	The algorithm used to compute a secure hash of the image data for this image. The result of the computation is displayed as the value of the `os_hash_value` property. The value might be `null` (JSON null data type). The algorithm used is chosen by the cloud operator; it may not be configured by end users. (Since Image API v2.7)
`os_hash_value`	body	string	The hexdigest of the secure hash of the image data computed using the algorithm whose name is the value of the `os_hash_algo` property. The value might be `null` (JSON null data type) if data has not yet been associated with this image, or if the image was created using a version of the Image Service API prior to version 2.7. (Since Image API v2.7)
`os_hidden`	body	boolean	This field controls whether an image is displayed in the default image-list response. A “hidden” image is out of date somehow (for example, it may not have the latest updates applied) and hence should not be a user’s first choice, but it’s not deleted because it may be needed for server rebuilds. By hiding it from the default image list, it’s easier for end users to find and use a more up-to-date version of this image. (Since Image API v2.7)
`protected`	body	boolean	A boolean value that must be `false` or the image cannot be deleted.
`schema`	body	string	The URL for the schema describing a virtual machine image.
`self`	body	string	The URL for the virtual machine image.
`size`	body	integer	The size of the image data, in bytes. The value might be `null` (JSON null data type).
`status`	body	string	The image status.
`tags`	body	array	List of tags for this image, possibly an empty list.
`updated_at`	body	string	The date and time when the resource was updated. The date and time stamp format is ISO 8601: CCYY-MM-DDThh:mm:ss±hh:mm For example, `2015-08-27T09:49:58-05:00`. The `±hh:mm` value, if included, is the time zone as an offset from UTC. In the previous example, the offset value is `-05:00`. If the `updated_at` date and time stamp is not set, its value is `null`.
`visibility`	body	string	Image visibility, that is, the access permission for the image.
`direct_url` (Optional)	body	string	The URL to access the image file kept in external store. It is present only if the `show_image_direct_url` option is `true` in the Image service’s configuration file. Because it presents a security risk, this option is disabled by default.
`locations` (Optional)	body	array	A list of objects, each of which describes an image location. Each object contains a `url` key, whose value is a URL specifying a location, and a `metadata` key, whose value is a dict of key:value pairs containing information appropriate to the use of whatever external store is indicated by the URL. This list appears only if the `show_multiple_locations` option is set to `true` in the Image service’s configuration file. Because it presents a security risk, this option is disabled by default.
