<br>
</span>I think we still desire some (basic no upgrades) support for<br>
non-containerized baremetal at this time.<br>

<br>
</span>It already supports this if use don't use the --heat-native option,<br>
also you can customize the container used for heat via<br>
--heat-container-image. So we already have this! But rather than do<br>
this I personally prefer the container to have python-tripleoclient<br>
and heat-monolith in it. That way everything everything is in there to<br>
generate Ansible templates. If you just use Heat you are missing some<br>
of the pieces that you'd still have to install elsewhere on your host.<br>
Having them all be in one scoped container which generates Ansible<br>
playbooks from Heat templates is better IMO.<br>

<br>
</span>Yes. Lets remove some of the undercloud logic. But do note that most<br>
of the undercloud specific login is now in undercloud_config.py anyway<br>
so this is mostly already on its way.<br>

<br>
</span>The wrapper could be just another set of playbooks. That we give a<br>
name too... and perhaps put a CLI in front of as well.<br>

<br>
</span>This would be configurable I think depending on which templates were<br>
used. Noop as a default for developer deployments but do note that<br>
some services like Neutron aren't going to work unless you have some<br>
basic network setup. Noop is useful if you prefer to do this manually,<br>
but our os-net-config templates are quite useful to automate things.<br>
