[Rdo-list] [RDO-Manager] Working with the overcloud

After jumping some hoops and with the help of the usual suspects on IRC, I was able to deploy an overcloud with HA, Network isolation and Ceph. Great!

Now I want to focus on what’s next, or how to manage this environment going forward. Let me give you a couple of examples:

After the installation of the overcloud, I was hit with the cinder bug described here: https://bugzilla.redhat.com/show_bug.cgi?id=1272572 <https://bugzilla.redhat.com/show_bug.cgi?id=1272572>  The issue is that the cinder.conf file needs to replace ‘localhost’ with the ip of the public keystone. What I did, based on the bugzilla, was to log in to each controller node and then update the value inside the cinder.conf file.
Is this one off the proper way to patch and keep the environment updated? I mean, one week from now we will find that a particular RPM needs to be updated, how do you handle this? I thought that the proper way was to recreate the TripleO image and redeploy.

Or another example is Ceph. Currently Tripleo installs version 0.8 and I want to install version 9 Inferno. What is the correct path to achieve this?

Additionally, let’s say that I want to install, say: CloudKitty (choose your alternate, non mainstream openstack project here)
Do we recreate the images and redeploy, or do a puppet run after they have been installed with a tool like Foreman/Katello?
