Comment 2 for bug 1979208

I believe this happens because of missing cache facts for zun containers. We take care of facts gathering inside playbook, but it seems we had a type in the playbook which lead to that failure.

As another workaround, you can try running simple ad-hoc against zun_all group, like:

  /opt/openstack-ansible$ ANSIBLE_GATHER_SUBSET="!all,hardware" ansible -m setup zun_all

This should also populate facts and cache them IIRC.
