Overview

Image lifecycle management supports global configuration and independent configuration for a specified image repository. If global image lifecycle management is enabled, the configured global rules are applied to all images of the root account. You can also configure an image tag automatic clearing policy for a specified image repository, and this policy has higher priority than the global configuration.

This document describes how to implement image lifecycle management through the TKE console.

Notes:

• For an image repository, the image tag automatic clearing policy configured specifically for this image repository has higher priority than a global image lifecycle management policy.
• After a global image lifecycle management policy is enabled, image tags are automatically cleared only after the number of image tags of the root account reaches the default quota.

Directions

Configuring global image lifecycle management

1. Log in to the TKE console, and choose Image Repositories -> My Images in the left sidebar.
2. On the My Images page, click Image Lifecycle Management. See the figure below.
