Define `become=yes' per role with Ansible

Question

In my system provisioning with Ansible, I don't want to specify become=yes in every task, so I created the following ansible.cfg in the project main directory, and Ansible automatically runs everything as root:

[privilege_escalation] become = True 

But as the project kept growing, some new roles should not be run as root. I would like to know if it is possible to have some instruction inside the role that all tasks whithin that role should be run as root (eg. something in vars/), instead of the global ansible.cfg solution above!

Answer 1

I have found a solution, although I think a better solution should be implemented by the Ansible team. Rename main.yml to tasks.yml, and then write the following to main.yml:

--- - { include: tasks.yml, become: yes } 

Another solution is to pass the parameter directly in site.yml, but the main idea of the question was reusing the role in other projects without forgetting it needs root:

--- - hosts: localhost   roles:     - { role: name, become: yes }
