RDO Manager does a lot more than packstack. Too much, for many use
cases, which is why we have people continuing to use packstack. Where do
people use packstack?
1. Demos
2. Development Work
3. CI
I'm sure there are others, but lets start there. I personally need
support for use cases 1 and 2. Can we get to the point where rdo-manager
can support these use cases?
There are, as I can see it, two potential approaches that could make
this work:
1. Treat the undercloud deployment as an all-in-one, and not deploy the
overcloud.
2. Have rdo-manager assume that the undercloud is already deployed, and
only deploy the overcloud.
Are there others?
I think that 2 is an interesting option? What if ... we took something
like the next gen oslab and put only an rdo-manager undercloud out on
it? Then...allowed multiple people to run rdo-manager --overcloud
against it, perhaps each with their own slice?
I'm already deploying OpenStack on OpenStack. If most of the business
logic/value add comes from the overcloud, can we split the deployment
along these lines?

Followup question - how do RDO Manager developers develop/test RDO
manager? Do you require access to a lab with several bare metal machines?

Hi Adam,
Revising this thread with my own reasons...

Installing OpenStack on low-end hardware (1 NIC, no IPMI) or in VMs with
nested virt. Personally, I have some NUCs for a personal OpenStack
cluster. I also have access to an internal OpenStack cloud and I want to
test ODL for Neutron on that.
Ultra simple deployment architecture (no HA, one controller, N compute
nodes, or all-in-one on a home server).
Personally, I'm OK manually powering on a host (when prompted) to PXE
boot an undercloud host. I don't know if it's even possible, but if we
could detect that hosts have only one NIC, using the same NIC for
management, data and provisioning, that would be awesome.
Thanks,
Dave.

I'm guessing IPMI is a requirement of the Ironic driver.

This would work with the overcloud approach.

Id plainly like to see a breakdown of how this compares to say FUEL, or HP
Helion, or IBMs openstack deployments
Though Id also like to see someone get RDO to work with XENServer
deployments also, seems RDO is pretty much kvm based only

While any compute nodes deployed by RDO would be KVM nodes, I don't see
any reason that someone couldn't add Hyper-V, ESX or Xen nodes to Nova's
compute pool with RDO - the bits are the same as upstream Nova, and of
course whether such a configuration is supported is not an issue.
In fact, I'm pretty sure that CERN deploys Hyper-V and KVM nodes using
RDO. I don't see any reason why someone couldn't do the same with Xen,
and document any issues they have on rdoproject.org
Thanks,
Dave.

For what it's worth, Ironic supports all kinds of interesting power
drivers, way more than just IPMI. DRAC, ILO, AMT, ssh (for virt), WOL (a
super-simple wake-on-lan driver that only knows how to power machines
on), etc. cc-ing Lucas for more info.

For what it's worth, Ironic supports all kinds of interesting power

I'm Guessing this is really what we want; an undercloud deployment
using ssh?
ssh (for virt),
Say I have a RHEL7 laptop. Could I install an undercloud deployment on
it, using the ironic driver as the target for my development, and then
install an overcloud on top of that?
WOL (a
super-simple wake-on-lan driver that only knows how to power machines
on), etc. cc-ing Lucas for more info.

CERN uses the RDO packages as the basis for the deployment to the 4,000 or soc Linux
servers. We use the cloudbase Windows packages for Hyper-V (a few hundred).
These are then glued together using the OpenStack puppet modules on both Windows and
Linux.
We do use packstack for our R&D work. It provides a really simple way of bringing up a
small OpenStack set up for newcomers in a few virtual machines to experiment or for us to
evaluate if a backport of a recent feature is useful. This sort of case is shown by the
RDO test days of new releases.
I have concerns that the rdo-manager model does not seem to address this packstack use
case (unless the undercloud is also deployed using rdo-manager). Using devstack for these
deployments would make it a much larger transition to a Puppet/RDO packaged based
configuration for production.
