Is there any way to output the roles_path in a task (not the specific path
to a role, I mean the search path)?
The doco for Ansible 2.5 says that roles are found in the ./roles directory
relative to the playbook file, and in /etc/ansible/roles.
"ansible-config list" says that roles are also found in ~/.ansible/roles,
/usr/share/ansible/roles and /etc/ansible/roles - the first two are not
mentioned in the doco.
It seems to me from my testing that roles are also found in the current
working directory, and in the playbooks directory.
I have a role called other_role (i.e., a directory called other_role,
containing a tasks directory containing main.yaml) in /tmp.
As a control, I have another role called local_role in ./playbooks/roles
Finally I have an extremely simple playbook in ./playbooks that references
the roles:
---
- hosts: localhost
roles:
- { role: local_role }
- { role: other_role }
If I place other_role in my ./playbooks/roles directory:
mv /tmp/other_role ./playbooks/roles
ansible-playbook -v playbooks/test.yaml --> both roles run
If I place other_role in my ./playbooks directory:
mv ./playbooks/roles/other_role ./playbooks
ansible-playbook -v playbooks/test.yaml --> both roles run
If I place other_role in my current working directory (my playbook
directory's parent) :
mv ./playbooks/other_role .
ansible-playbook -v playbooks/test.yaml --> both roles run
If I place other_role in /etc/ansible/roles:
sudo mv ./other_role /etc/ansible/roles
ansible-playbook -v playbooks/test.yaml --> both roles run
If I place other_role back in the /tmp directory (or anywhere else except
the above four locations), running the playbook produces a "role not found"
error:
mv ./other_role /tmp
so it seems to me that the search path for roles contains at least these
four locations:
- the current working directory
- the directory containing the playbook
- the roles directory relative to the directory containing the playbook
- /etc/ansible/roles
Plus the other two that ansible-config reports (that I didn't test):
- ~/.ansible/roles
- /usr/share/ansible/roles
Is all this expected? In what order are these locations checked when a role
is referenced?
