Open Stack

Hello,

I prefer for kolla to create the bridge automatically.  Each node has two
physical interfaces. The network_interface and neutron_external_interface
options are set in the inventory file.

> you need set octavia_network_interface and configure external switch properly

I have octavia_network_interface set to "{{ api_interface }}" and api_interface
is set to "{{ network_interface }}", the defaults.

What do you mean by "configure external switch properly"? If you mean the
external option when creating OpenStack networks, then I used the defaults
in globals.yml which does not include that option. If you mean the physical
switch, I'm using a low-budget switch I had lying around that is not configurable.

Thanks for the help - everything else with kolla-ansible has been fairly easy.

Hi Stuart:

Usually, you need to add a bridge to all network nodes,  you can use "ovs-vsctl add-br  {br-name}" to add a ovs bridge, then you need to add a physical port  to that bridge by executing "ovs-vsctl  add-port {bridge} {port}".
another alternatives, you can append the physical port to neutron_external_interface variable in globals.yml.  in this case, kolla will create the ovs bridge automatically.
both of them, you need set octavia_network_interface and configure external switch properly.

if you really don't know how this works, I propose you  use   "octavia_network_type: tenant"  ref: [0] , in this case, kolla-ansible will setup the octavia management network for you, you don't need to do anything.

thanks.

Hello,

I enabled Octavia on a kolla-ansible installed Openstack
cluster. When I try to launch a loadbalancer instance, the
octavia-worker.log file reports:
"WARNING octavia.amphorae.drivers.haproxy.rest_api_driver [-]
Could not connect to instance."

I researched enough to know that the problem has to do with networking
between the controller and the lb-mgmt-net network. I initially
overlooked this in the kolla-ansible Octavia documentation:
"If using a VLAN provider network, ensure that the traffic is also bridged
to Open vSwitch on the controllers." But, I don't know how to do it.

Help to create the necessary bridge would be greatly appreciated.

Thanks,
-Stu
