Hi,

I need help with the internal_lb_vip_address/external_lb_vip_addresses.
I've found several posts people asking for a clarification of the purpose
and settings of that load balancers.
One of the discussions pointed to
https://github.com/openstack/openstack-ansible/blob/a46a72aa7838a3d500e8e397038c6fbded21745c/etc/openstack_deploy/openstack_user_config.yml.example#L103-L118,
but that's unclear to me.
Does openstack-ansible (17.0.0.0b2 on CentOS7) take care of those load
balancers or do I need to configure them manually (if so how?)?

Taking
https://docs.openstack.org/project-deploy-guide/openstack-ansible/pike/app-config-prod.html
as an example I thought that internal_lb_vip_address of 172.29.236.9
corresponds to the deployment host, but when running
setup-infrastructure.yml I see haproxy are being configured on the infra
nodes (.11, .12, .13) and listen on 172.29.236.9:8181.

Since there is no service listening on 8181 on the deployment host
172.29.236.9 I'getting the behavior described in
https://ask.openstack.org/en/question/104307/openstack-ansible-pip-issues-while-installing-the-infrastructure/

Cheers,

Marcin
