# Ansible Basics

Ansible is an open source automation tool used to configure multiple computers at the same time.

## Ansible Playbooks 

Text files / Configuration files written in YAML language which tells ansible what to do & how to do it.

Ansible can work with **1 or multiple systems** in your infrastructure at the same time. Ansible establishes connection between these servers using **SSH for Linux** & Power shell remoting for windows.

Information about target systems is stored in **Inventory file**.

Its in Playbooks where we define what we want Ansible to do. Playbook has **set of tasks** to be run on Hosts. Task is an action performed on the Hosts. 

Eg. Execute a command, Run a script, Install a package, Shutdown / Restart.

## Modules 

The different actions run by tasks are called modules. Different types of modules are System modules, Files, database, cloud, windows, etc.   

## Syntax 

To run a playbook -> ansible-playbook <playbook file name>
