role dependencies - path to parent role's templates folder

[ProfHase]

I am deploying multiple web applications that all have 4 tasks in common:

- name: copy nginx conf
  template:
     src=nginx.conf
     dest=/etc/nginx/{{ inventory_hostname }}.conf

- enable nginx conf
  file:
    state=link
  ...

- name: copy certs
  ....

- name: copy chain
  ...

To avoid this redundancy, I tried to define a meta role: `nginx` with the tasks above and set this role as dependency in every webapp role

# webapp1-role meta/main.yml

dependencies: {name: nginx, tags: [nginx]}

Unfortunately the nginx role does not search in `templates` folder of the `webapp1-role`

Does the `nginx` role somehow know about the role it is called with?
Or how would I prevent this redundancy?

Maybe you can give a relative path to the template module. So from
your role nginx you need to set a path something like this:

template: src=../webapp1-role/templates/foobar

Thanks Johannes,
the problem about it is: There is no way to pass the role path of the ``webapp1-role`` to the ``nginx`` role ( I'd rather not hardcode it, so that I could use nginx as dependence for multiple roles)
The

{{ role_path }}

always resolves to the nginx role

You can't? At least it does for me:

dependencies:
- { role: foobar, my_variable: whatever }

That way you can include a fail task in your nginx role (to fail when
the variable is not set) and use the variable as path to the file.
Untested...
