ansible loop with include_variable - ansible

Question

I have a playbook, there are multiple yaml files under include_vars section of the task as you see i am defining them individually one by one. I'm wondering if i can pass them through the loop.
I went through the google and ansible doc link here but i don't find loop example however, i see with_first_found but i don't want that.
My playbook below
---
- name: Creating aws host
hosts: localhost
connection: local
become: yes
tasks:
- include_vars: awsvariable.yml
no_log: true
- include_vars: vaults/mysecrets.yml
no_log: true
- include_vars: vaults/mydev.yml
no_log: true
- include_vars: requirements.yml
Below is what i am considering
Is this doable as below?
tasks:
- include_vars: "{{ item }}"
loop:
- awsvariable.yml
- vaults/mysecrets.yml
- vaults/mydev.yml
- requirements.yml
OR
tasks:
- include_vars: ['awsvariable.yml', 'vaults/mysecrets.yml', 'vaults/mydev.yml', 'requirements.yml']
no_log: true
Please suggest, if we can better align them some other way around.
ansible version: 2.9
BR.

Answer 1

I see you are already close to your answer and yes loop should work, try to run your play in the dry run mode and set the no_log: false to see if your variables are getting expanded.
Example:
$ ansible-playbook test_play.yml --check --ask-vault-pass
your code
- include_vars: "{{ item }}"
loop:
- 'awsvariable.yml'
- 'vaults/mysecrets.yml'
- 'vaults/mydev.yml'
- 'requirements.yml'
no_log: true

Use dir to include all the files in a folder.
- name: Include variable files
include_vars:
dir: vars
extensions:
- "yml"
Alternatively can use both loop or with_items to loop through the filenames and include them.
- name: Include variable files
include_vars: "{{ item }}"
with_items:
- "vars/file.yml"
- "vars/anotherfile.yml"
Or using the newer loop.
- name: Include variable files
include_vars: "{{ item }}"
loop:
- "vars/file.yml"
- "vars/anotherfile.yml"

Seems the include_vars module can't work with loops. You could use the include_task module to loop over a file that has a single task to include_vars:
---
- hosts: localhost
gather_facts: false
vars:
files_to_load:
- file1.yml
- file2.yml
- file3.yml
tasks:
- include_tasks: include_vars.yml
loop: "{{ files_to_load }}"
loop_control:
loop_var: file_to_load
ant the include_vars.yml file:
- name: include vars {{ file_to_load }}
include_vars: "{{ file_to_load }}"
UPDATE:
Regarding loop syntax that i tried and didnt work, the below attempts failed:
1st:
- include_vars: "{{ item }}"
loop: - "{{ files_to_load }}"
2nd:
- include_vars: "{{ item }}"
loop:
- "{{ files_to_load }}"
i am aware that this syntax works:
- name: Include variable files
include_vars: "{{ item }}"
loop:
- "vars/file.yml"
- "vars/anotherfile.yml"
but personally i dont find convenient the fact that you need to list the loop items on task level.
