Does OSP support running each service in an LXC container as well?
What about nova-cells? How does it handle people who need to carry
local changes? What is the upgrade path like with OSP?
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.
venv is not really sufficient, as the system level binaries can still
conflict (MysQL and LDAP both require system libraries for Keystone, for
example)
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.
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.

This would not be acceptable for those running OSP.

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

I would not recommend an approach targetting RHEL that does not use
packages.
OSAD support for RHEL using packages would be an outstanding tool.
Which way are you planning on taking it?

Hey everyone,
I've started looking at osad, and I like much of the direction it
takes.
I'm pretty interested in developing it to run on RHEL, I just
wanted to
check if anyone would be -2 opposed to that before I spend cycles on
it.
