DescribeImages - Elastic Compute Service - Alibaba Cloud ドキュメントセンター

Queries available images. When you call this operation, you can specify parameters, such as ImageId, ImageFamily, and InstanceType, in the request.

Operation description

Usage notes

You can query your custom images, public images provided by Alibaba Cloud, Alibaba Cloud Marketplace images, and shared images from other Alibaba Cloud accounts.
This is a paginated query. The response contains the total number of available images and the images on the returned page. By default,10 entries are displayed on each page.
When you call an API operation by using Alibaba Cloud CLI, you must specify request parameter values of different data types in the required formats. For more information, see Parameter formats.
If you set ImageOwnerAlias to system or others when you call the DescribeImages operation to query public images that are provided by Alibaba Cloud or shared images, Resource Access Management (RAM) policies are ignored in the request. For more information, see RAM authorization.

Debugging

You can run this interface directly in OpenAPI Explorer, saving you the trouble of calculating signatures. After running successfully, OpenAPI Explorer can automatically generate SDK code samples.
