Hi Team,

I need a playbook to update the sudoer file based on os distribution. I have written below code but it is failing.

- name: Copy sudoers files  
copy:  
src: files/{{ file\_name }}  
dest: /etc/sudoers  
validate: /usr/sbin/visudo -csf %s  
{% if ansible\_distribution == “amazon” %}  
file\_name: ‘sudoers.aspera’  
{% elif ansible\_distribution == “Debian” %}  
file\_name: ‘sudoers.debian’  
{% else %}  
file\_name: ‘sudoers.general’  
{% end %}

The offending line appears to be:

validate: /usr/sbin/visudo -csf %s  
{% if ansible\_distribution == “amazon” %}  
^ here

Regards

Do as the following, which will make playbook readable

file\_name: sudoers.general  
tasks:

- name: Set file name when Amazon  
set\_fact:  
file\_name: “sudoers.aspera”  
when: ansible\_distribution == ‘amazon’

- name: Set file name when Debian  
set\_fact:  
file\_name: “sudoers.debian”  
when: ansible\_distribution == ‘Debian’

- debug:  
msg: “{{ file\_name }}”

This is also possible

vars:  
file\_name\_mapping:  
amazon: “sudoers.general”  
debian: “sudoers.debian”  
tasks:

- debug:  
msg: “{{ file\_name\_mapping[ansible\_distribution] | default(‘sudoers.general’)}}”
