You have said that overlay networks are involved,
and are now talking about load balancers. Is this Neutron LBaaS?
As far as I know, a Neutron LBaaS instance is "one-armed"
--- both the VIP and the back endpoints have to be on the same Neutron
network. But you seem to have all the k8s services on a single subnet.
So I am having some trouble following exactly what is going on. Can
you please elaborate?</font></blockquote><div><br></div><div>Hi Mike,<br><br></div><div>Thanks for reaching out and thanks for going over the video!<br><br></div><div>For those following at home, we are talking about the explanation I gave about slide 18 in [1].<br><br></div><div>This topic was also discussed in the work sessions about Kubernetes integration (maybe also in the architecture one, but I don't remember it for sure). The further explanation I gave in the work session is that the setup we use is having a Neutron network with a subnet for all the load balancer pools and then each Kubernetes namespace have a different Neutron net and subnets. To make it work, we have all the subnets (including the load balancer one) connected to a single `raven` router. This is not blocked by the API and I think according to the LB spec it should work, although I have not tried it with ovs.<br><br></div><div>Christophe (CCed) is trying to verify this OVS usage.<br></div><div><br><br></div><div>[1] <a href="http://www.slideshare.net/celebdor/project-kuryr-returns-docker-delivered-kubernetes-next">http://www.slideshare.net/celebdor/project-kuryr-returns-docker-delivered-kubernetes-next</a></div><div> <br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><br><br><font face="sans-serif" size="2">BTW, there is also some discussion of
