DescribeImages - Elastic Compute Service - Alibaba Cloud Documentation Center

Queries available images.

Description

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 operation supports paged query. The response contains the total number of available images and the number of 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 required formats. For more information, see Parameter format overview.

Debugging

OpenAPI Explorer automatically calculates the signature value. For your convenience, we recommend that you call this operation in OpenAPI Explorer. OpenAPI Explorer dynamically generates the sample code of the operation for different SDKs.
