Hello Flint,

what version of Kubernetes are you deploying on top of Openstack ?

are you using the external Openstack cloud controller ? I tested it an
it works only if you have at least v.1.10.3

Look at this page:

Please test that you can make a SSL termination on the loadbalancer,
describing it with Kubernetes yaml files. That is important for
production operation. Test also if you have downtime when you have to
renew SSL certificates.

You will also want to check that traffic that hits your pods has the
HTTP header X-Forwarded-For, or even better the IP packets you receive
at the Pods have the source IP address of the original client.

If needed test everything also with IPv6

I personally decided not to use Octavia, but to go for the Kubernetes

The key idea is that instead of Openstack controlling the LoadBalancer
having Octavia spinning up a VM running nginx, you have Kubernetes
controlling the LoadBalancer, running a nginx-container.
At the end you need a nginx to reverse proxy, you have to decided if
this resource is managed by Openstack or Kubernetes.

Keep in mind that if you go for a kubernetes ingress controller you
can avoid using nginx. There is already an alternative ha-proxy
