$vi get_compute_info.yml
- name: Get and print instance IP
hosts: localhost
gather_facts: False

- name: Get VM infos
os_server_facts:
auth:
auth_url: https://openstack-identity.mygroup/v2.0

This is very verbose. Lots of information is displayed. Usually only the IP address is needed to access the new instance via SSH.
