Using multiple config files using same template in a role in ansible

Question

I want to use a role with a template and want to use multiple config wiles with different names and values. I am using the group_vars directory which is on the same level as the playbook which hosts its runs.

Here's my sample playbook

---
- hosts: emea-stg-web
  vars_files:
    - group_vars/ssh_user.yml
  remote_user: "{{ ssh_user }}"
  become_user: root

  roles:
    - nginx-install
    - php5.6-install

I want to have each "item" in the role use different values, like variable "proj" can have values ["pro1","pro2","pro3"] in an iterative way. Any way I store them in a file.

- hosts: emea-stg-web
  vars_files:
    - group_vars/ssh_user.yml
  remote_user: "{{ ssh_user }}"
  become_user: root

  roles:
    - nginx-install
      with_items:
      - test1
      - test2
      - test3
    - php5.6-install

Answer 1

Go through this include_role module:

tasks:
  - include_role:
      role: nginx-install
      vars_from: "{{ item }}"
    with_items:
      - vars_file1
      - vars_file2

Also the group_vars directory is intended to store var files for host groups, so use it for that purpose only.
