Create an Ansible Playbook which will dynamically load the variable file named same as OS_name and just by using the variable names we can Configure our target node.( Note: No need to use when keyword here. )

Description: Configure Apache webserver in RedHat and Ubuntu OS using Ansible Playbook. For RedHat OS we have httpd as a package name whereas for Ubuntu OS we have apache2 package for apache webserver.

AWS Console

Launched two instances of Redhat and Ubuntu/Debian OS

ansible facts for RedHat

We are going to use two variable from the ansible facts i.e distribution and distribution_major_version in the ansible playbook to load the variable file dynamically.

Create a variable file for Redhat and Ubuntu in a format like (<distribution>-<distribution_major_version>.yml)

(Note: It is case sensitive)

(RedHat-8.yml)
package_name: httpd
service_name: httpd
src_file: redhat.html

ansible facts for Ubuntu

(Ubuntu-20.yml)
package_name: apache2
service_name: apache2
src_file: ubuntu.html

I created different html file for Ubuntu (ubuntu.html) and RedHat (redhat.html) OS

(ubuntu.html)
Ubuntu's  Apache2

and

(redhat.html)
Redhat's  httpd

This is the main ansible playbook

(task.yml)
- hosts: all
vars_files:
    - "{{ansible_facts['distribution']}}-{{ansible_facts['distribution_major_version']}}.yml"
tasks:
  - name: "Downloading httpd"
    package:
       name: "{{ package_name }}"
       state: present
- name: "starting httpd service"
    service:
       name: "{{ service_name }}"
       state: started
- name: "Coping html pages"
    copy:
       dest: "/var/www/html"
       src: "{{src_file}}"

After running the PlayBook check the webserver configured or not
