glance-scrubber is a utility for the Image Service that cleans up images that have been deleted; its configuration is stored in the glance-scrubber.conf file. Multiple instances of glance-scrubber can be run in a single deployment, but only one of them can be designated as the cleanup_scrubber in the glance-scrubber.conf file. The cleanup_scrubber coordinates other glance-scrubber instances by maintaining the master queue of images that need to be removed.
