I agree to follow this project's code of conduct.
I have checked the current issues for duplicates.
I understand that ansible-rulebook is open source software provided for free and that I might not receive a timely response.

Bug Summary

I have a simple ansible playbook which prints variables defined in host_vars and group_vars files defined in the inventory directory. If I execute the playbook with ansible-playbook (or ansible-runner), the tasks can be executed. If I trigger it by a webhook via ansible-rulebook the variables are not found.

Environment

OS: WSL2, Ubuntu 22.04.3 LTS
Ansible:

ansible [core 2.16.0]
  config file = None
  configured module search path = ['/home/evonlanthen/.ansible/plugins/modules', '/usr/share/ansible/plugins/modules']
  ansible python module location = /home/evonlanthen/.local/lib/python3.10/site-packages/ansible
  ansible collection location = /home/evonlanthen/.ansible/collections:/usr/share/ansible/collections
  executable location = /home/evonlanthen/.local/bin/ansible
  python version = 3.10.12 (main, Nov 20 2023, 15:14:05) [GCC 11.4.0] (/usr/bin/python3)
  jinja version = 3.0.3
  libyaml = True

Ansible-rulebook:

Actual results

Ansible-playbook run fails with undefined variable (it doesn't matter if a variable from group_vars or hosts_vars is used first).

Expected results

Successful ansible playbook run.

Synchronizing the directories to the ansible playbook main directory solves the issue:

for TYPE in host group; do
  rsync -av inventories/*/${TYPE}_vars/ ${TYPE}_vars/
done

It there a better way?

Hi @evonlanthen Thanks for the report.
Indeed I see two different bugs.

When the inventory is a file, we only copy the file and we don't take into account other potential files.
If the inventory is a directory, we are not setting correctly the path.

I'm going to fix them in #683

Hi @Alex-Izquierdo

Thanks for your investigation and your fix.

Kind regards
Elmar

mkanoor · 2024-05-16T15:36:45Z

@evonlanthen When you ran the ansible-rulebook command line can you use the directory name for inventory without the file name e.g

ansible-rulebook -i inventories

@evonlanthen When you ran the ansible-rulebook command line can you use the directory name for inventory without the file name e.g
ansible-rulebook -i inventories

If I specify the directory only, no hosts are found anymore. The same happens with:

ansible-rulebook -i inventories/production

Alex-Izquierdo · 2024-05-23T16:45:39Z

@evonlanthen When a directory is set it should take the whole directory as inventory. This is what is going to fix: #684

Alex-Izquierdo linked a pull request May 16, 2024 that will close this issue

fix: set correct inventory path when it is a dir #684
