Ansible: How to iterate over a role with an array?

Question

Is it possible to call a role multiple times in a loop like this:

vars:
  my_array:
    - foo
    - bar
    - baz 
roles:
  - role: foobar
    with_items: my         


        

Answer 1

There's no way to loop over a role currently but as mentioned in that Google Group discussion you can pass a list or dict to the role and then loop through that internally.

So instead you could do something like:

# loop_role/tasks/main.yml

- name: debug item
  debug: var="{{ item }}"
  with_items: my_array

And then use it like this:

- hosts: all
  vars:
    my_array:
      - foo
      - bar
      - baz 
  roles:
    - { role: loop_role, my_array: "{{ my_array }}" }
