<br>
I think it can be reduced to a single manifest per node.<br>
Also, when a review is created it would be easier to check if you create one <br>
review for the python, puppet, tests and release notes.<br>

<br>
I would like to have packstack to be multi node since the requirements for <br>
TripleO are still to big for PoC.<br>
<br>
But it is :-<br>
<br>
RDO Mitaka ML2&OVS&VXLAN (VLAN) <br>
Controller+Network+N*Compute+Storage (CONFIG_UNSUPORTED=y)<br>
Controller/Network+N*Compute+Storage <font size="2"><span style="font-size:10pt;">(CONFIG_UNSUPORTED=y)</span></font><br>
Just external OVS bridge on Controller/Network ( Network) has to be configured manually.<br>
It works fine unless HA Controller(s) is a must.<br>
Some posts to this thread sound like intend to drop features present and working all way long
<br>
in packstack. I hardly understand why working features should be dropped due to not passing through CI.<br>
Yes , conversion system to DVR requires several updates after packstack pre-deployment,<br>
but I would never compare Packstack with Devstack due to<br>
<br>
1. Packstack installs different services on different nodes exactly as answer-file instructs it to do.<br>
2. Devstack starts a bunch of non-restart able ( in meantime ) daemons on one or several nodes,
<br>
<br>
Thanks.<br>

Does it make sense to convert packstack to an ansible module?<br>

<br>
I started a refactor [1] as part of a manifest cleanup, unifcation and to<br>
start de refactor discussion, i'm happy that Javier took the puppet-openstack-integration<br>
road. <br>
Another idea around this refactor is to make packstack create manifests<br>
that can be used even without packstack runs, installing them in the proper puppet
<br>
environment directories and setting the OPM path as part of the this OpenStack? environment,<br>
thus making packstack a puppet manifest generator...<br>
<br>
Cheers,<br>
