[ansible-project] Get all groups from parent group

[starflighter . one]

Hi guys,

I want to get all existent subgroups from a parent group.

Example Playbook:

---
- hosts: "test"

  tasks:
  - group_by:
     key: "{{ansible_distribution}}-{{ansible_distribution_major_version}}"
     parents: "dist"

  - debug: var="{{ groups['dist'] }}"
    run_once: true

#unfortunately I only get all the hosts of the parent group instead the 
groups created by 'group_by'

#Something like {% for group in groups['dist'] %} .... {% endfor %} ??
#or this:
  - name: test
    command: echo {{ item }}
    with_items: "{{ groups['dist'] }}"
    delegate_to: localhost
    run_once: true

#-> only hosts... :-(


Any ideas?

Thanks,
starflighter
