TripleO to deploy Ceph standlone

Here is a nice Christmas present: you can use TripleO for a standalone Ceph deployment, with just a few lines of YAML. Assuming you have an undercloud ready for a new overcloud, create an environment file like the following:

No default is going to fit everybody, but we want to know what the default is to improve from there. So let's try and see:

Ceph for Cinder in TripleO

This said, should $subject sound interesting to you, beware the code still …
