In tripleo-common/playbooks/roles/octavia-controller-config/tasks/main.yml playbook controller's node hostname is obtained using shell script. It should rather be collected using Ansible's facts. Especially because it uses hostname -f command which is not recommended even in its own manual:
If a machine has multiple network interfaces/addresses or is used in a mobile environment, then it may either have multiple FQDNs/domain names or none at all. Therefore avoid using hostname --fqdn, hostname --domain and dns‐domainname. hostname --ip-address is subject to the same limitations so it should be avoided as well.
It happened to me that deployment was failing because hostname -f was not working properly:
