<p>Hi Esra,</p>
<p>Take a look at Virtuozzo, which is supported in Nova via libvirt
virt_type=parallels. It provides both VMs and OS Containers
similar to lxc except our containers have beed in production for
more than 10 years already. Though
<a class="moz-txt-link-freetext" href="http://docs.openstack.org/developer/nova/support-matrix.html">http://docs.openstack.org/developer/nova/support-matrix.html</a> looks
a bit outdated, you still can use Libvirt Virtuozzo CT column to
understand what features are supported.<br>

<div>Not sure what's your use case, but I would also take a
look at nova LXC driver. It looks like you are treating
your Containers as VMs and for that I would say the nova
lxc driver is a better fit. [1] Docker has specific
requirements on images and networking, which doesn't fit
well in the nova model imo.</div>
<div><br>
</div>
<div>There is also a new hypervisor LXD which aims to treat
containers as VMs as well. [2]</div>

<div dir="ltr">I guess "extra virtualization

<div>I think you could consider using Magnum
with Ironic driver. If the driver is
Ironic, COEs are deployed to nova
instances that are physical machines
provided by Ironic. Zun project [1] could
be another option for your use case. Zun
is similar to nova-docker, which enables
running containers on compute hosts. You
could find a thoughtful introduction here

<br>
It is very sad to hear nova-docker's
retirement. Me and my team (3) are<br>
working for a cloud computing
laboratory and we were very keen on<br>
working with nova-docker.<br>
After some research about its current
state I saw these mails. Will you<br>
actually propose another equivalent to
nova-docker or is it just the<br>
lack of contributors to this project?<br>
Some of the contributors previously
advised us the magnum project<br>
instead of nova-docker, however it
does not satisfy our needs because of<br>
the additional virtualization layer it
needs.<br>
If the main problem is the lack of
contributors we may participate in<br>
this project.<br>
</blockquote>
There's never any need to ask permission
to contribute to a project :) If
nova-docker driver is something you
cannot do without, feel free to
contribute to it.<br>
<br>
That said, Magnum does seem to be where
most of the docker-related contributions
to the compute landscape have moved. So,
it's more likely you will find company
in that project and perhaps be able to
make more effective contributions there.
Can I ask what is the "extra
virtualization layer" that you are
referring to in Magnum?<br>
<br>
Best,<br>
