I just put up <a class="moz-txt-link-freetext" href="https://review.openstack.org/#/c/79088/">https://review.openstack.org/#/c/79088/</a> for review to
get the teeth-agent imported into openstack. I'm not sure if we want
this merged immediately or if we want to get the outstanding
non-Openstack dependencies settled before then, but hopefully this
can help get things started.<br>

<div>Great to hear you are going to move towards Pecan+WSME.
Yesterday I had a look at teeth projects. Next few days I am
going to start contributing. First of all, I think, we need to
arrange all that stuff about pluggable architecture. I've
created a wiki page about Ironic python agent <a
moz-do-not-send="true"
href="https://wiki.openstack.org/wiki/Ironic-python-agent">https://wiki.openstack.org/wiki/Ironic-python-agent</a>. </div>
<div><br>
</div>
<div>And the question about contributing. Have you managed to
send pull request to openstack-infra in order to move this
project into <a moz-do-not-send="true"
href="http://github.com/stackforge">github.com/stackforge</a>?
Or we are supposed to arrange everything (werkzeug ->
Pecan/WSME, architectural questions) before we move this agent
to stackforge?</div>

<div>Hey, I'm on the team working on this agent, let me
offer a little history. We were working on a system of
our own for managing bare metal gear which we were
calling "Teeth". The project was mostly composed of:</div>
<div><br>
</div>
<div>1. teeth-agent: an on-host provisioning agent</div>
<div>2. teeth-overlord: a centralized automation mechanism</div>
<div><br>
</div>
<div>Plus a few other libraries (including teeth-rest,
which contains some common code we factored out of the
agent/overlord).</div>
<div><br>
</div>
<div>A few weeks back we decided to shift our focus to
using Ironic. At this point we have effectively
abandoned teeth-overlord, and are instead focusing on
upstream Ironic development, continued agent development
and building an Ironic driver capable of talking to our
agent.</div>
<div><br>
</div>
<div>Over the last few days we've been removing
non-OS-approved dependencies from our agent: I think
teeth-rest (and werkzeug, which it depends on) will be
the last to go when we replace it with Pecan+WSME
sometime in the next few days.</div>
<div><br>
</div>
<div>Thanks,</div>

<div>The Ironic team has been
discussing the need for a "deploy
agent" since well before the last
summit -- we even laid out a few
blueprints along those lines. That
work was deferred and we have
been using the same deploy ramdisk
that nova-baremetal used, and we
will continue to use that ramdisk
for the PXE driver in the Icehouse
release.</div>
<div><br>
</div>
<div>That being the case, at the
sprint this week, a team from
Rackspace shared work they have
been doing to create a more
featureful hardware agent and an
Ironic driver which utilizes that
agent. Early drafts of that work
can be found here:</div>

target="_blank">https://github.com/rackerlabs/ironic-teeth-driver</a><br>
</div>
<div><br>
</div>
<div>I've updated the original
blueprint and assigned it to Josh.
For reference:</div>

</div>
<div><br>
</div>
<div>I believe this agent falls
within the scope of the baremetal
provisioning program, and welcome
their contributions and
collaboration on this. To that
effect, I have suggested that the
code be moved to a new OpenStack
project named
"openstack/ironic-python-agent".
This would follow an independent
release cycle, and reuse some
components of tripleo
(os-*-config). To keep the
collaborative momentup up, I would
like this work to be done now
(after all, it's not part of the
Ironic repo or release). The new
driver which will interface with
that agent will need to stay on
github -- or in a gerrit feature
branch -- until Juno opens, at
which point it should be proposed
to Ironic.</div>
<div><br>
</div>
<div>The agent architecture we
discussed is roughly:</div>
<div>- a pluggable JSON transport
layer by which the Ironic driver
will pass information to the
ramdisk. Their initial
implementation is a REST API.</div>
<div>- a collection of
hardware-specific utilities
(python modules, bash scripts,
what ever) which take JSON as
input and perform specific actions
(whether gathering data about the
hardware or applying changes to
it).<br>
</div>
<div>- and an agent which routes the
incoming JSON to the appropriate
utility, and routes the response
back via the transport layer.</div>
