Upper Limit for Image Garbage Collection

It specifies that image garbage collection will be triggered when the available disk space reaches a certain percentage.

If it is set to a large value, the disk space may be insufficient, affecting the stability of nodes and containers. If it is set to a small value, there may be unnecessary and overly frequent image deletions, which will increase the system load.

Value Range

0–100

To disable image garbage collection, set this parameter to 100.

Default Value

80

Modifiable

Yes

Scope

CCE standard and CCE Turbo clusters

Suggestions

If disk space is limited or container images are frequently updated, you can lower the threshold to avoid running out of disk space. If there is plenty of storage available, you can increase the threshold, so that images will be garbage collected less frequently. Unless otherwise specified, keep the default settings.
