Red Hat Enterprise Linux Server release 7.6 (Maipo)
[root@openshift-master-0 ~]# ls /etc/yum.repos.d/

[root@openshift-master-0 ~]# 
======================================================
1) repo setup
   copy rhos-release rpm
   yum install -y rhos-release-latest.noarch.rpm
   rhos-release 14-director -p passed_phase2
   yum update -y; reboot
   
2) yum install git ansible tmux -y
   git clone https://github.com/smalleni/sahasra
   
3) let infrared use nodes topology from ./plugins/virsh/defaults/topology/nodes
create ssh-key and add it to authorized_keys

In undercloud /home/stack create cloud.yml with below content i.e 
(undercloud) [stack@undercloud-0 ~]$ cat /home/stack/clouds.yml 
clouds:
  undercloud:
   auth:
    username: admin
    password: o9MoCYyS7JK7jHG2Y2Bp3Gzmi
    project_name: admin
    auth_url: https://192.168.24.2:13000/
    user_domain_name: Default
    project_domain_name: Default
Note: I didn't install openstack ansible modules explicitly in undercloud or ansbile (i.e infrared) host.

Ansible playbook in infrared(ansbile) node os_ports.yml
---
- hosts: localhost
  remote_user: stack
  tasks:
  - name: os get ports
    os_port_facts:
      cloud: undercloud
      port: 053e8a57-70dd-4e72-bc1f-4eb35b052b38
    delegate_to: undercloud-0
I ran it like
(undercloud) (.venv) [stack@gprfc044 ansible]$ ansible-playbook -vvv os_ports.yml

output is
