By: Fabio Alessandro Locati

Overview of this book

Ansible is an open source automation platform that assists organizations with tasks such as application deployment, orchestration, and task automation. With the release of Ansible 2.7, even complex tasks can be handled much more easily than before. Learning Ansible 2.7 will help you take your first steps toward understanding the fundamentals and practical aspects of Ansible by introducing you to topics such as playbooks, modules, and the installation of Linux, Berkeley Software Distribution (BSD), and Windows support. In addition to this, you will focus on various testing strategies, deployment, and orchestration to build on your knowledge. The book will then help you get accustomed to features including cleaner architecture, task blocks, and playbook parsing, which can help you to streamline automation processes. Next, you will learn how to integrate Ansible with cloud platforms such as Amazon Web Services (AWS) before gaining insights into the enterprise versions of Ansible, Ansible Tower and Ansible Galaxy. This will help you to use Ansible to interact with different operating systems and improve your working efficiency. By the end of this book, you will be equipped with the Ansible skills you need to automate complex tasks for your organization.

Rocket Chat

Many companies like the functionality of Slack, but do not want to lose out on the privacy that an on-premises service gives you when using Slack. Rocket Chat is an open source software solution that implements most of the features of Slack, as well as the majority of its interface. Being open source, every company can install it on-premises and manage it in a way that is compliant with their IT rules.

As Rocket Chat's goal is to be a drop-in replacement for Slack, from our point of view, very few changes need to be done. In fact, we can create the uptime_and_rocket.yaml file with the following content:

---
- hosts: localhost
connection: local
tasks:
- name: Read the machine uptime
command: 'uptime -p'
register: uptime
- name: Send the uptime to rocketchat channel
