<div>Hi, all,</div>
<div><br>
</div>
<div>Let me recap what is hyper and the idea of hyperstack. </div>
<div><br>
</div>
<div><span style="line-height:1.5">Hyper is a single-host runtime engine.</span><span style="line-height:1.5"> </span>Technically, </div>

</div>
</blockquote>
<div><br>
</div>
I do not understand the last line above. My understanding is that AUFS == UnionFS, which is used to implement a storage driver for Docker. Others exist for btrfs, and devicemapper. You select which one you want by setting an option like this:</div>
<div><br>
</div>
<div>DOCKEROPTS=<span><span>”</span>-s devicemapper<span>”</span></span></div>
<div><br>
</div>
<div style="max-width:590px">Are you trying to say that with Hyper, AUFS is used to provide layered Docker image capability that are shared by multiple hypervisor guests?</div></div><div style="max-width:590px"><br></div></div></div></blockquote><font color="#000000"><div class="gmail_quote" style="max-width:590px"><font color="#000000">Peng >>> Yes, AUFS implies the Docker images here.</font></div><br></font><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div><div style="font:Verdana normal 14px;color:#000"><div>
<div>My guess is that you are trying to articulate that a host running Hyper is a 1:1 substitute for a host running Docker, and will respond using the Docker remote API. This would result in containers running on the same host that have a superior security
isolation than they would if LXC was used as the backend to Docker. Is this correct?</div></div><div><br></div></div></div></blockquote><font color="#000000"><div class="gmail_quote" style="max-width:590px"><font color="#000000">Peng>>> Exactly</font></div></font><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div><div style="font:Verdana normal 14px;color:#000"><div>

<div><span style="line-height:1.5">Due to the shared-kernel nature of LXC, Docker lacks of the necessary isolation in a multi-tenant CaaS platform, and this is what Hyper/hypervisor is good at.</span></div>
<div><br>
</div>
<div>And because of this, most CaaS today run on top of IaaS: <a href="https://trello-attachments.s3.amazonaws.com/55545e127c7cbe0ec5b82f2b/388x275/e286dea1266b46c1999d566b0f9e326b/iaas.png" target="_blank">https://trello-attachments.s3.amazonaws.com/55545e127c7cbe0ec5b82f2b/388x275/e286dea1266b46c1999d566b0f9e326b/iaas.png</a></div>

<div>From the tech stack perspective, Hyperstack turns Magnum o run in parallel with Nova, not running on atop.</div>

<div><br>
</div>
For this to work, we’d expect to get a compute host from Heat, so if the bay type were set to “hyper”, we’d need to use a template that can produce a compute host running Hyper. How would that host be produced, if we do not get it from nova? Might it make more
sense to make a dirt driver for nova that could produce a Hyper guest on a host already running the nova-compute agent? That way Magnum would not need to re-create any of Nova’s functionality in order to produce nova instances of type “hyper”.</div></div></div></div></blockquote><font color="#000000"><div class="gmail_quote" style="max-width:590px"><font color="#000000"><br></font></div><div class="gmail_quote" style="max-width:590px"><font color="#000000">Peng >>> We don’t have to get the physical host from nova.

In a HyperVM instance, there is no docker daemon, cgroup and namespace (except MNT for pod). VM serves the purpose of isolation. We plan to support cgroup and namespace, so you can control whether multiple containers in a pod share the same namespace, or completely isolated. But in either case, no docker daemon is present.</font></div><div class="gmail_quote" style="max-width:590px"><font color="#000000"><br></font><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div><div style="font:Verdana normal 14px;color:#000"><div>

Team,
<div><br>
</div>
<div>I woud like to ask for your input about adding support for Hyper in Magnum:</div>
<div><br>
</div>
<div><a href="https://blueprints.launchpad.net/magnum/+spec/hyperstack" target="_blank">https://blueprints.launchpad.net/magnum/+spec/hyperstack</a></div>
<div><br>
</div>
<div>We touched on this in our last team meeting, and it was apparent that achieving a higher level of understanding of the technology before weighing in about the directional approval of this blueprint. Peng Zhao and Xu Wang have graciously agreed
to respond to this thread to address questions about how the technology works, and how it could be integrated with Magnum.</div>
<div><br>
</div>
<div>Please take a moment to review the blueprint, and ask your questions here on this thread.</div>
<div><br>
</div>
<div>Thanks,</div>
<div><br>
