Ubuntu 16.04 - How to Install Ansible

What is Ansible:

Ansible is an open source automation platform. It can help you with configuration management, application deployment and task automation.

Ansible works by configuring client machines from an computer with Ansible components installed and configured.

How it works:

Ansible communicates over normal SSH channels in order to retrieve information from remote machines, issue commands, and copy files. Because of this, an Ansible system does not require any additional software to be installed on the client computers (agentless). Any server that has an SSH port exposed can be brought up and configured by Ansible.

Environment:

OS: Ubuntu 16.04

Install Ansible:

1. Add Ansible's PPA (Personal Package Archive) to your system.

$ sudo apt-add-repository ppa:ansible/ansible
 Ansible is a radically simple IT automation platform that makes your applications and systems easier to deploy. 
Avoid writing scripts or custom code to deploy and update your applications— automate in a 
language that approaches plain English, using SSH, with no agents to install on 
remote systems.
