Querying Images

Function

This API is used to query images using search criteria and to display the images in a list.

URI

GET /v2/cloudimages

You can type a question mark (?) and an ampersand (&) at the end of the URI to define multiple search criteria. For details, see the example request.

Table 1 Parameter description

Parameter

Mandatory

Type

Description

  • KooGallery image: The value is market.
NOTE:

The __imagetype of images you share with other tenants or those other tenants share with you and you have accepted is shared. You can use field owner to distinguish the two types of shared images. You can use member_status to filter out shared images you have accepted.

__whole_image

No

Boolean

Specifies whether the image is a full-ECS image. The value can be true or false.

__system__cmkid

String

Specifies the ID of the key used to encrypt the image. You can obtain the ID from the IMS console or by calling the Querying Image Details (Native OpenStack API) API.
