Yep, that's pretty much it.

Makes sense. Is there a discussion going on for this or some patch set
adding this functionality? I will be happy to be part of that effort.

Thanks Nir for pointing that out [1]. I am considering moving to LBaaSv2
moving forward.

 I was talking about the HAProxy used to provide load balancing to
OpenSatck services [2]. Sorry for the confusion, i hope that explains.

Yeah, there's work under way to allow custom placement of services, but
for the moment it would probably need to run on the controllers.

Assuming the service supports this, it should be doable.

It's possible, but to my knowledge there isn't any existing support for
LBaaS in TripleO.  To enable it, you would need to:

-Add it to the TripleO loadbalancer puppet manifest:
https://github.com/openstack/puppet-tripleo/blob/master/manifests/loadbalancer.pp
-Add the necessary hieradata to enable it in tripleo-heat-templates.

This is assuming there is existing puppet support for it.  If not, there
would be some additional steps to get that into the puppet modules we use.

Hi Qasim,

Replied inline to your non-triple-o specific related questions.
Also regarding your following email, any specific reason you try to use
LBaaSv1?
I highly recommend that you go with LBaaSv2 (you may still choose haproxy
if you wish), since LBaaSv1 is deprecated[1] and will be removed[2]
sometime in the future.

I have not tested this myself, but I suspect you will run into some
difficulties. The VIP for your loadbalancer is actually a neutron port. a
port contains a hostname in its binding information.

Adding to the provided information in the previous email. I am trying to
enable lbaasv1 with HAproxy.
