=======================================================
|
|
Spec Lite: Add glance-cache-manage utility using v2 API
|
|
=======================================================
|
|
|
|
:project: glance
|
|
|
|
:problem: In Rocky, the v1 dependant glance-cache-manage command was removed
|
|
while removing Images API v1 entry points. As a part of Edge
|
|
computing glance cache needs to be enabled on far-edge nodes
|
|
via Split Control plane where glance-cache-manage utility will be
|
|
essential to queue image for prefetching, to list & delete images
|
|
from Image Cache.
|
|
|
|
:solution: In Stein, as per Edge computing architecture, glance cache will be
|
|
enabled on far-edge nodes. Hence it will be good to add
|
|
glance-cache-manage utility using v2 API in glance. This utility
|
|
will have the following commands and the same interface as Queens
|
|
glance-cache-manage utility [0] insofar as possible,
|
|

|
|
|

|

$ glance-cache-manage --host=<HOST> list-queued

|
|
$ glance-cache-manage --host=<HOST> delete-cached-image <IMAGE_ID>

$ glance-cache-manage --host=<HOST> delete-all-cached-images
|
|
