delegate_facts does not work with container connection plugin

[Logan V]

http://logs.openstack.org/92/507092/2/check/gate-openstack-ansible-openstack-ansible-ceph-ubuntu-xenial/ce71081/console.html#_2017-10-06_00_51_31_111103

The delegate_facts that occurs here does not actually assign the facts to the ceph-mon container, because even though the fact is delegated to the container's inventory_hostname, you can see from the task output that it is being delegated to the container's ansible_host instead, so the facts are never mapped back to the inventory_hostname.

The facts seem to be stored in the host "{{ item }}" ... see the cache:

# ls -1 /etc/openstack_deploy/ansible_facts/\{\{\ item\ \}\}
/etc/openstack_deploy/ansible_facts/{{ item }}

^ this contains the facts collected by this delegate_facts task

I haven't been able to reproduce this. It seems to be working as expected after testing on an AIO.

Created a test playbook that would delegate from a glance hosts to all nova hosts:

---
- name: delegate test
  hosts: glance_all[0]
  gather_facts: no
  tasks:
    - name: gather facts from nova hosts
      setup:
      delegate_to: "{{item}}"
      delegate_facts: True
      with_items: "{{ groups['nova_all'] }}"

    - name: lookup addresses of nova hosts
      debug:
        msg: "{{ hostvars[item]['ansible_default_ipv4']['address'] }}"
      with_items: "{{ groups['nova_all'] }}"

I used the same playbook as jimmy, with the exception that I added gather_facts: yes.
Same result, no issue.

[Logan V (loganv)]

I was seeing it on Ocata. I wonder if we're missing a necessary backport. Let me do some more testing on various branches and see if I can get a useful repro instruction together :)

[Jean-Philippe Evrard (jean-philippe-evrard)]

I tried in Ocata, same issue as Logan.

Sorry, I guess that's pretty much stale, going to close this.
