Unable to use "tripleo_podman" role on Centos-8

[Cédric Jeanneret]

Hello,

There's something wrong with the "tripleo_podman" role provided by tripleo-ansible:
[root@undercloud ~]# ansible -m include_role -a name=tripleo_podman -e 'tripleo_container_registry_insecure_registries=["localhost","undercloud.ctlplane"]' localhost
localhost | SUCCESS => {
    "changed": false,
    "include_args": {
        "name": "tripleo_podman"
    }
}
localhost | FAILED! => {
    "msg": "No file was found when using first_found. Use errors='ignore' to allow this task to be skipped if no files are found"
}

The files that should be affected by that role do exist in /etc/containers - and seeing that message, it's apparently due to the "with_first_found" located in the main.yaml:
https://opendev.org/openstack/tripleo-ansible/src/branch/master/tripleo_ansible/roles/tripleo_podman/tasks/main.yml#L23-L33

Fun fact, the same call with another role (tripleo_image_serve) does work without any issue... And that one doesn't have that "with_first_found":
https://opendev.org/openstack/tripleo-ansible/src/branch/master/tripleo_ansible/roles/tripleo_image_serve/tasks/main.yml

The ansible version on that CentOS-8 node is:
ansible 2.9.1
  config file = /etc/ansible/ansible.cfg
  configured module search path = ['/root/.ansible/plugins/modules', '/usr/share/ansible/plugins/modules']
  ansible python module location = /usr/lib/python3.6/site-packages/ansible
  executable location = /bin/ansible
  python version = 3.6.8 (default, Nov 21 2019, 19:31:34) [GCC 8.3.1 20190507 (Red Hat 8.3.1-4)]

Maybe there's a change on how it handles errors/missing files for that specific module in 2.9.x?

Cheers,

C.

Nice misleading error message: the real issue was the missing facts.... So the current syntax still works, but will raise some deprecation warning. The change is still valid.
