Automating Simple Tasks

As mentioned in the previous chapter, Ansible can be used to both create and manage a whole infrastructure, as well as be integrated into an infrastructure that is already working.

In this chapter, we will cover the following topics:

• YAML
• Working with Playbook
• Ansible velocity
• Variables in Playbook
• Creating the Ansible User
• Configuring a basic server
• Installing and configuring a web server
• Publishing a website 
• Jinja2 templates

First, we will talk about YAML Ain't Markup Language (YAML), a human-readable data serialization language that is widely used in Ansible.
