This isn’t terribly useful, as you can just specify the value directly in the task. However, if the task uses the same value multiple times, it can be useful to make it a variable. A good example of this is the Apache2 package.

On Debian-based machines, the Apache2 configuration file lives at /etc/apache2/apache2.conf. On RedHat-based machines, the Apache2 configuration file lives at /etc/httpd/httpd.conf. Instead of providing apache2 or httpd multiple times, you can use a task-level variable, as follows:

---

- hosts: all

tasks:

- template: src=webserver.conf dest=”/etc/{{name}}/{{name}}.conf”

vars:

name: apache2
