Ansible-Jinja2 Templating.

Jinja2 is one of the most powerful and famous python-based template engines. Jinja2 template is able to access the variables in ansible. In Ansible playbook, we generally have to change a lot of configuration & values for each server which is time consuming. With jinja2 templating, one can change variables only to that template which results in saving a lot of time and an easily manage the config changes in systems.

When using jinja templating, it good to give the extension .j2

- hosts: webserver
  vars:
    pkg_name: httpd
    http_port: 8080
    web_path: /var/www/html

      name: "{{ pkg_name }}
      state: present

    template:
