octavia health manager bind host

i have deployed Octavia services and neutron LBaaS agent from kolla-ansible. kolla deploys vanilla Octavia and I'm struggling a bit with post deployment configuration. specifically the management port configuration for the health manager service - there is no documentation on this so I have been searching around the web. So, the health manager needs access to the amphora instances that run on the lb-mgmt-network - to achieve this, we need to create a neutron port on that networks subnet and record the ports id, mac and ip address - then using this information create an interface on the br-int switch e.g. o-hm0 (octavia-healthmanager0)

I have created the interface and configured it with the mac, and id of the neutron port on lb-mgmt-subnet and the ovs interface is bound to the host. I have tested connectivity to test instances on the lb-mgmt-subnet and I can access them directly from the host.

However because the interface is bound to only one host, only one of my 3 controllers have access to the amphorae - what is the correct way to configure this port for 3 network controllers - do I need to create a port for each host and them bind to the controllers VIP in octavia config? - any pointers would be much appreciated.

Hi, Yes, if you are using the local port binding method to get access to the lb-mgmt-net for the controllers, you would do the same procedure on each controller to provide it a port on the lb-mgmt-net.

There are many ways to setup the lb-mgmt-net. Some folks use provider nets, other vxlan connections, etc. The OpenStack Ansible role uses a provider network. I will also note that you can use routes to access the lb-mgmt-net as well, it does not need to be a L2 network to function correctly.

Sorry we have not had the resource to write up the detailed installation guide with example network configurations yet, it will happen in the future.

I failed to understand and create this o-hm0 interface. Could someone please provide a step by step guide to get connectivity from/to the control nodes to the lb-mgmt-net by using OVS and o-hm0?
