Overview
This proposal aims to recover an image which is in 'pending-delete' state so as to provide the revert capability for the purposes of allowing emergency operational action to recover from an accidental delete
General Workflow
- The 'delayed_delete' config entry is enabled in glance-api.conf
- Delete the specific image
- List the images which are 'pending-delete'
- User PUT /v2/images/{image-uuid} on the requested image to recover it
- Eventually, the requested image should be in 'active' state after recovering successfully.
Design Details
HTTP Request - PUT /v2/images/12345678-1234-1234-1234-123456789abc

}
Known code impact
1. List pending-delete image
2. Only the image which in 'active' status can be recovered to 'pending-delete'
