ansible.legacy.setup\n - module failed to execute on jenkins pipeline - jenkins

Question

I'm using Jenkins to launch a simple Ansible Pipeline (to create a folder on localhost as follow
name: Play1
hosts: localhost
become: true
remote_user: ec2-user
tasks:
- name: Create directory
file:
path: /home/ec2-user/Newfolder
state: directory
group: ec2-user
owner: ec2-user
mode: 0700
But when i build the pipeline I got this error message:
TASK [Gathering Facts] *********************************************************
fatal: [localhost]: FAILED! => {"ansible_facts": {}, "changed": false, "failed_modules": {"ansible.legacy.setup": {"failed": true, "module_stderr": "sudo: a password is required\n", "module_stdout": "", "msg": "MODULE FAILURE\nSee stdout/stderr for the exact error", "rc": 1}}, "msg": "The following modules failed to execute: ansible.legacy.setup\n"}
Have you an idea about this error please ?

Answer 1

I think you are not providing the sudo password, and the ansible_user is not already configured for passwordless sudo. Following is the error from the snippet you provided.
{"failed": true, "module_stderr": "sudo: a password is required\n",
In the playbook, you have provided become: true and remote_user: ec2-user
become: true
remote_user: ec2-user
So your ec2-user is not having permission to become a root user without password being passed. You can run sudo -l command to check what a user can do with his current sudo configurations.
If you do not want to change the sudoers file, then simply pass -K flag to the playbook while execution to get prompted for the sudo password.
-K, --ask-become-pass
However, the user ec2-user must be in a sudoer file; without it you will an error like the below regardless of supplying ec2-user password via -K
ec2-user is not in the sudoers file
