Hi,
I have been experiencing a rather peculiar issue when using an in-house
dynamic inventory (output
here: https://gist.github.com/oboukili/4bfc95d97fc340e770321201f70dce4c )
in conjunction with static group_vars files.
When using this simple playbook:
---
- hosts: infrastructure
become: true
pre_tasks:
- name: debug
debug:
msg: "{{ hostvars[item] }}"
with_items: "{{ groups['infrastructure'] }}"
...
## Invocation:
ansible-playbook -i ~/Workspaces/ansible-inventory/mycloud includes/test.yml
## Output:
PLAY [infrastructure]
***********************************************************************************************************************************************************************************************
TASK [Gathering Facts]
**********************************************************************************************************************************************************************************************
ok: [apps-public1]
ok: [bastion]
TASK [debug]

'/home/bki/Workspaces/playbooks/test.yml': line 5, column 7, but may\nbe
elsewhere in the file depending on the exact syntax problem.\n\nThe offending
line appears to be:\n\n pre_tasks:\n - name: debug\n ^ here\n"}
fatal: [bastion]: FAILED! => {"failed": true, "msg": "the field 'args' has an

When I delete the group_vars folder, everything runs fine (but I lose, of
course all the static configuration).
More specifically, I did a lot of debugging with the use of the inventory
script and without, and I pinpointed the issue to the
ansible.template.AnsibleJ2Vars.__get_item__() getter
(ansible/template.vars.py) that silently fails on this particular step when
mixing dynamic inventory script and static group_vars files:
variable = self._templar._available_variables[varname]".
(its value would then not be a hostvars object instance, but a string:
"Unable to get repr for <class 'ansible.vars.hostvars.HostVars'>")
Could anybody have pointers?
Thanks a lot,
--Olivier
