Hello,

Yes openstack-ansible does support deploying keepalived along with
haproxy. The keepalived role is run just before the haproxy role in
this playbook: https://github.com/openstack/openstack-ansible/blob/master/playbooks/haproxy-install.yml#L27-L31

You can see an example keepalived configuration in the prod config
example of the OSA deployment guide:
