command: echo "Flag exists"
delegate_to: localhost
when: flag_check.stat.exists
Explanation:
Delegation combined with conditional logic ensures tasks are executed only under specific circumstances.

Retrieve and display a list of available files in a directory using the lookup plugin.
정답:
- name: List directory files hosts: localhost
tasks:
- name: Get files in directory set_fact:
files: "{{ lookup('pipe', 'ls /tmp') }}"
- debug:
var: files
Explanation:
