Updating Image Information (Native OpenStack API)

Function

This API is used to modify image information.

Constraints

Only customized attributes, image name, and image description can be modified.

URI

PATCH /v2/images/{image_id}

Table 1 lists the parameters in the URI.

**Table 1** Parameter description
Parameter	Mandatory	Type	Description
image_id	Yes	String	Specifies the image ID. For details about how to obtain the image ID, see Querying Images.

Request

Request parameters

Glance has two methods of updating image information. The method is specified by Content-Type in the HTTP header. application/openstack-images-v2.0-json-patch and application/openstack-images-v2.1-json-patch are supported. Content types differ only in the format of the request message body.

**Table 2** v2.1 request message body
Parameter	Mandatory	Type	Description
[Array]	Yes	Array of objects	For details, see Table 3.

**Table 3** Data structure description of the [Array] field
Parameter	Type	Mandatory	Description
op	String	Yes	Indicates the type of the update operation, including replacing, adding, and deleting an attribute. The value can be replace, add, or remove.
path	String	Yes	Indicates the name of the target attribute. For replace and remove, the value can only be an existing attribute of the image. For add, the value can be an existing or a new attribute. If the value is an existing attribute, add takes the same effect as replace. If the value is a new attribute, the add operation is performed. Add a slash (/) before the attribute name.
value	String	No	Indicates the value of the attribute to be updated or added. Mandatory for replace and add, and not for remove

**Table 4** v2.0 request message body
Parameter	Mandatory	Type	Description
[Array]	Yes	Array of objects	For details, see Table 5.

**Table 5** Data structure description of the [Array] field
Parameter	Type	Mandatory	Description
replace	String	Mandatory for any of the three values	Indicates that an image attribute will be replaced. The value is the attribute to be replaced and a slash (/) must be added in front of the attribute name.
add	String		Indicates that an image attribute will be added. The value is the attribute to be added and a slash (/) must be added in front of the attribute name.
remove	String		Indicates that an image attribute will be deleted. The value is the attribute to be deleted and a slash (/) must be added in front of the attribute name.
value	String	Mandatory for replace and add, and not for remove	Indicates the value of the attribute to be updated or added. For detailed description, see Image Attributes.
