Ansible requirements.yml: ERROR! Expected role dependencies to be a list

General Discussion

Hi, is this expected?

(ansible) jose@jose-t14s:~/projects/phoebe_aee$ ansible-galaxy install -f -r ./requirements.yml 
Starting galaxy role install process
- changing role osc.open_ondemand from v3.0.1 to unspecified
- downloading role 'open_ondemand', owned by osc
- downloading role from https://github.com/OSC/ood-ansible/archive/v3.0.1.tar.gz
- extracting osc.open_ondemand to /home/jose/.ansible/roles/osc.open_ondemand
- osc.open_ondemand (v3.0.1) was installed successfully
ERROR! Expected role dependencies to be a list. Role osc.open_ondemand (v3.0.1) has meta/requirements.yml {'collections': ['community.general']}
(ansible) jose@jose-t14s:~/projects/phoebe_aee$ cat requirements.yml 
---
#collections:
#  - name: awx.awx
#  - name: community.general
roles:
  - name: osc.open_ondemand

Google returns only one (!) instance of this error message from this ansible feature proposal…

Second and more relevant content is this bugreport, Documentation on requirements.yml is confusing or misleading · Issue #73347 · ansible/ansible · GitHub - where member of Ansible staff says:

We do not support dependencies between stand alone roles and collections

so isn’t meta/requirements.yml actually using some old/invalid syntax? Anyway I must admit that I’m not ansible guru…

What version of ansible are you running? That syntax appears to be correct. Seems like that was last updated when I was fixing linting issues. So I’m guessing you’re using an older ansible version than we are.

https://docs.ansible.com/ansible/latest/galaxy/user_guide.html#install-multiple-collections-with-a-requirements-file

What version of ansible are you running?

2.14.2, full version info below.

The more I read docu the more it seems to me that role can not have collection as a dependency. But it is not explicitly stated anywhere - there is only that

Role dependencies let you automatically pull in other roles when using a role.

(source).

(ansible) jose@jose-t14s:~/projects/phoebe_aee$ ansible-galaxy --version
ansible-galaxy [core 2.14.2]
  config file = None
  configured module search path = ['/home/jose/.ansible/plugins/modules', '/usr/share/ansible/plugins/modules']
  ansible python module location = /usr/lib/python3/dist-packages/ansible
  ansible collection location = /home/jose/.ansible/collections:/usr/share/ansible/collections
  executable location = /usr/bin/ansible-galaxy
  python version = 3.11.2 (main, May 30 2023, 17:45:26) [GCC 12.2.0] (/usr/bin/python3)
  jinja version = 3.1.2
  libyaml = True

The outcome: After even more reading of Ansible documentation, I learned that ansible execution environments, involved in this case are actually not expected to contain role at all - the fact it’s actually somehow partially (pretending) that it’s working was subject of my confusion.

So I think the unexpected behavior reported above is actually fine and it is not indicating bug in OOD Ansible code.
