huge forklift to get that work done though adding in distinct code paths for deployments powered by packages would be a lot more work. As for Fedora support, I dont think thats far off once we have a base RHEL/CentOS7 system running.</span></font></div>

<p>To be clear the present OSAD project really has no intention to bring package based installations of OpenStack. We'd certainly not reject the idea and wouldn't mind having an implementation spec for it but all of our current tooling and design principles
have been based on the fact that we've move away from distro packages and on to upstream source as it pertains to OpenStack. The system as it stands today creates an internal repository of built wheels for your environment and all of the OpenStack services
are installed within LXC containers, where possible and it makes sense. The installation of these bits comes from the internal wheel repository and uses pip and all of the pre / post config happens within the Ansible playbooks.<br>
</p>

<br>
I understand your frustration with the packaging approach. For a first approximation, getting the code for OpenStack/Python operations out of Pip makes sense. Ideally, we would be able to support both approaches. Red Hat would not support a pip based install,
but I am sure some Centos base users would be happy with pip.<br>
<br>
We had the same general discussion around devstack. <br>

<p>One issue that will become a problem, for users of RedHat specifically, is the fact that RedHat has no LXC container templates (at least none that are publicly available) and even if someone were to make an official RedHat container template there'd be issues
with the containers being able to connect to the satellite servers as well as other potential license problems.
<br>

<br>
I'd leave the issues with getting blessed RHEL LXC support to Red Hat. Making something that works for CentOS with publically available LXC containers there would be more what I expect from OSAD upstream.<br>
<br>
What about Fedora support? It seems to me that we would be far more likely to have something supportable with Fedora that could then be backported to CentOS?<br>

<p>I've done some experimenting with a RedHat 7.1 hosts and CentOS 7 containers and things seem to work OK but I'd not say that I have really put a lot of effort into it. That said, if its something that you'd all like to work on I'd be happy to help out to
make it all go. <br>

Sounds good. I'll give it a try after the Keystone Midcycle.<br>

<br>
So, ignoring the Hypervisor for the moment, there is no reason that the rest of the controllers can't run in separate Containers. I think a container based deployment would be fantastic.<br>
<br>
venv is not really sufficient, as the system level binaries can still conflict (MysQL and LDAP both require system libraries for Keystone, for example)<br>
<br>
From an Ansible perspective; we need to be able to share the HTTPD instance for Keystone and Apache, and getting that right will solve most of the issues deploying in a secure manner. Putting Them on separate hosts or containers should be a degenerate case,
and thus be supported, too.<br>

<div>Asking, because in Philly the general consensus, I fel,t was people want to move away from the current system level package stuff and move towards: venv's, "lightweight packages", containers. The only reason that was brought up to keep packages around
was to solve the non-python lib stuff and using a depsolver (yum/apt) that doesn't suck (pip). So I am pretty sure my wants are inline with what other people in the community are either already doing or moving towards.</div>

<div>I should be more clear. My current thought is to have a venv packaged</div>
<div>inside an rpm - so the rpm includes the needed init scripts, ensures the</div>
<div>required system level binaries are installed, adds the users - ect ect.</div>
<div>But would be a single deployable autonomous unit. Also, have a versioning</div>
<div>schema to roll forward and back between venvs for quick update/rollback.</div>
<div>We are already working on doing something similar to this to run kilo on</div>
<div>cent6 boxen, until we can finish revving the remaining parts of the fleet</div>
<div>to cent7.</div>
<div><br>
</div>
<div>My desire is to move away from using system level python & openstack</div>
<div>packages, so that I can possibly run mismatched versions if I need to. We</div>
<div>had a need to run kilo ceilometer and juno neutron/nova on a single</div>
<div>server. The conflicting python requirements between those made that task</div>
<div>impossible. In general I want to get away from treating Openstack as a</div>
<div>single system that everything needs to be upgraded in lock step (packages</div>
<div>force you into this). I want to move to being able to upgrade say</div>
<div>oslo.messaging to a newer version on just say nova on my control plane</div>
<div>servers. Or upgrade nova to kilo while keeping the rest of the system</div>
<div>(neutron) on juno. Unless I run each service in a vm/container or on a</div>
<div>physical piece of hardware that is pretty much impossible to do with</div>
<div>packages - outside of placing everything inside venv's.</div>
<div><br>
</div>
<div>However, it is my understanding that OSAD already builds its own</div>
<div>python-wheels and runs those inside lxc containers. So I don¹t really</div>
<div>follow what good throwing those into an rpm would really do?</div>
