Utilizing packaging infrastructure to efficiently replication images between

Registered by Dwight Hubbard on 2013-04-30

An efficient way to install images to glance services in multiple zones and across geographically distributed datacenters. This will use existing geographically distributed packaging infrastructure to securely distribute openstack images into glance servers in a number of clusters.

Whiteboard

Requirements:
    * Can leverage existing infrastructure
    * Data is only copied one time from the source of truth into a zone
    * Secure, does not require root level trust between hosts

Some work similar to this was discussed at the Havana Design Summit, and has produced several blueprints related to a one-time clone operation that copies an image and its metadata from one glance deployment/endpoint to another. There was not any strong consensus on continued replication throughout the life of the clone, though there already exists glance-replicator* which may cover your use case.

An interesting idea but it looks like we'll need to get more cloning and replication in place before we can see how it fits. However, due to age I'm considering it abandoned for now.
