I'm trying to get the output of my Ansible script using register module but the loop I'm using is probably causing some issue.
Whats a default way of using register module with loop?
Code:
---
- name:
hosts:
gather_facts:
tasks:
- name: Execute file
ansible.builtin.shell:
environment:
"setting environment"
register: output
loop:
"value"
- debug:
vars: output.std_lines
Whats a default way of using
registermodule withloop?
It is just registering the result.
The only difference will be, that a single task will provide you just with an dictionary result (or output in your example) and registering in a loop will provide with a list result.results (or output.results in your example). To access the .stdout_lines you will need to loop over the result set .results too.
You may have a look into the following example playbook which will show some aspects of Registering variables, Loops, data structures, dicts and lists and type debugging.

- hosts: localhost
become: false
gather_facts: false
tasks:
- name: Create STDOUT output (single)
command: 'echo "1"'
register: result
- name: Show full result (single)
debug:
var: result
- name: Show '.stdout' (single)
debug:
msg: "The result in '.stdout': {{ result.stdout }} is of type {{ result.stdout | type_debug }}"
- name: Create STDOUT output (loop)
command: 'echo "{{ item }}"'
register: result
loop: [1, 2, 3]
loop_control:
label: "{{ item }}"
- name: Show full result (loop)
debug:
var: result
- name: Show '.stdout' (loop)
debug:
msg: "The result in '.stdout': {{ item.stdout }} is of type {{ item.stdout | type_debug }}"
loop: "{{ result.results }}"
loop_control:
label: "{{ item.item }}"
By running it and going through the output you can get familiar with the differences in your tasks.
