And don't forget about:

Sounds pretty similar (the proxy could proxy to anything, etc.d,
zookeeper, a email system, a snail, a web-service, whatever...).

Chmouel,
Nice!
Ben added a topic "Alternative file formats for oslo.config" for
Liberty[1]. this would be great if we can talk about alternative
backends as well :)

Hello,
While on a long oversea flight with Sebastien Han we were talking how he had
implemented ceph-docker with central configuration over etcd. We quickly
came up to the conclusion that if we wanted to have that in Kolla it would
be neat if it was done straight from oslo.config so that would quickly
override the default keys in a central point.
There is multiple advantage to use that method not just for containers but
as well to avoid issues when orchestrating an openstack deployment.
I have heard arguments that this should be the job of an ansible/puppet/chef
tool and while I completely agree I just don't think it has to write to
files the tool would just write to the etcd database.
I have quickly came up with a quick and dirty POC on oslo.cfg here :
https://github.com/chmouel/oslo.config/commit/01ee54dd5219b1434eaac422055b58e77694d89f
and the demo :
https://gist.github.com/chmouel/05fb715f96344161268c
What others thinks about it ?
I believe if we wanted to do that we would have to add a stevesdor based
modular backend support directly to oslo.cfg first and have an etcd backend
implemented.

PS: I am using etcd here cause it's easy and fancy but this could be any
backends like a DB/NoSQL/Swift or whatever if we wanted
