Open Stack

Hi Team,,

Upon further debugging, I found that pre-introspection internally calls the
ansible playbook located at path /usr/share/ansible/validation-playbooks
File "dhcp-introspection.yaml" has hosts mentioned as undercloud.

- hosts: *undercloud*
  become: true
  vars:
...
...


But the artifacts created for dhcp-introspection at
location /home/stack/validations/artifacts/<some_random_number>_dhcp-introspection.yaml_2021-10-01T11
has file *hosts *present which has *localhost* written into it as a
result of which when command gets executed it gives the error *"Could not
match supplied host pattern, ignoring: undercloud:"*

Can someone suggest how is this artifacts written in tripleo and the way we
can change hosts file entry to undercloud so that it can work

Similar is the case with other tasks
like undercloud-tokenflush, ctlplane-ip-range  etc

Regards
Anirudh Gupta
