Pass complex variables into roles

Hi folks,

I’m facing an issue with roles call in plays when passing complex var. I want to find a way to pass variable by reference like so:

`
#group_vars/python-app/fooapi.yml

fooapi:
uno: 1
dos: 2

`
#group_vars/python-app/barapi.yml

fooapi:
uno: 1000
dos: 2000

`

`

`
#play.yml

  • hosts: python-app
    roles:
  • { role: python, app: fooapi}
    - { role: python, app: barapi}

`

`
#roles/python/tasks/main.yml

  • debug: var=app

`

This is maybe a bad practice but if we found a solution, this is a very usefull and nice way to do what I want to do.

Thank you for your help :slight_smile:

Hi folks,

Maybe there is no solution for that exactly. I want to make a role that is completly free from looping over a list of complex map like so:

`

group_vars/python-app/apps.yml

-python_apps:

  • name: foo
    uno: 1
    dos: 2
    […]
  • name: bar
    uno: 1000
    dos: 2000
    […]

`

`

roles/python-apps/tasks/main.yml

  • include: install.yml
    with_items: “{{python_apps}}”
    tags:
  • python-apps
  • install

`

`

roles/python-apps/tasks/install.yml

  • debug: var={{item.name}}

`

The role itself is maintenable, but the group_vars file containing all complex data structures will become huge and hard to maintain. What do you do in this case?

Thanks !
