Hi. I'd be interested in hearing from people who have implemented some form of replication with glance. I'm especially interested in how you went about it. I attended the session at the dev summit, but that was forward looking, and I am pretty sure that there wasn't any mention of current implementations.
I'll get the ball rolling -- I have just implemented API level replication for glance for an internal project. It uses the glance API to replicate images from a master glance to slave glances. Its not very smart at the moment, it just copies everything. Current warts: - no support for metadata update - no support for filtering of what is replicated - maintaining amazon ec2 ids across regions requires twiddling the nova database where this mapping is stored Advantages of this approach: - API level replication means that I can run different versions of glance at each end of the replication relationship - it really wasn't that hard to do Would other people be interested in getting this code into glance, probably as a stand alone command line tool? Or has someone done something much better that I should be using instead?
