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

Here is a code sample for using include_role looping on my_array:

- name: Use role in loop
  include_role:
    name: myrole
  loop: "{{ my_array }}"

Answer 2

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 }}" }

Answer 3

The include_role module is documented here: https://docs.ansible.com/ansible/include_role_module.html

According to the docs it was introduced in Ansible 2.2 already

Answer 4

I used something like below on Ansible version 2.8

tasks:
  - name: looping role to create multiple filesystem
    include_role:
      name: /opt/ansible/playbook/app_filesystem
    vars:
      vgname: "{{ item.vgname }}"
      lvname: "{{ item.lvname }}"
      lvsize: "{{ item.lvsize }}"
      mountpoint: "{{ item.mountpoint }}"
    loop:
      - { vgname: 'vgapp', lvname: 'lvapp', lvsize: '30g', mountpoint: '/app' }
      - { vgname: 'vgapp', lvname: 'lvappzk', lvsize: '64g', mountpoint: '/app/z' }
      - { vgname: 'vgapp', lvname: 'lvappdatazk', lvsize: '+100%FREE', mountpoint: '/app/data/zookeeper' }

tasks:
  - name: looping role to create multiple filesystem
    include_role:
      name: /opt/ansible/playbook/app_filesystem
    vars:
      vgname: "{{ item.vgname }}"
      lvname: "{{ item.lvname }}"
      lvsize: "{{ item.lvsize }}"
      mountpoint: "{{ item.mountpoint }}"
    loop:
      - { vgname: 'vgapp', lvname: 'lvapp', lvsize: '30g', mountpoint: '/app' }
      - { vgname: 'vgapp', lvname: 'lvappzk', lvsize: '64g', mountpoint: '/app/zookeeper' }
      - { vgname: 'vgapp', lvname: 'lvappdatazk', lvsize: '+100%FREE', mountpoint: '/app/data/zookeeper' }

Now supported as of Ansible 2.3.0:

- name: myrole
  with_items:
    - "aone"
    - "atwo"
  include_role:
    name: myrole
  vars:
    thing: "{{ item }}"
