I hit a similar issue a while back and found
https://github.com/ansible/ansible/issues/24987 which explains why
refresh_inventory doesn't cover this case.
Based on that, I ended up using include_vars to explicitly include the
variables onto the hosts after creating the yml file. E.g.
- hosts: localhost
gather_facts: false
tasks:
# use stat module to determine if "{{ inventory_dir }}/group_vars/all.yml"
exists
# create all.yml when it doesn't
- hosts: all
gather_facts: false
tasks:
- include_vars:
file: "{{ inventory_dir }}/group_vars/all.yml"
when: hostvars['localhost'].... #whatever you registered in the top host so
this only happens if all.yml was created
Bit of a hack, but it works. If you set up the when's properly then it
becomes idempotent and safe to include multiple times.
Hope that helps.
