Implementing DevOps with Ansible 2

By: Jonathan McAllister

Overview of this book

Thinking about adapting the DevOps culture for your organization using a very simple, yet powerful automation tool, Ansible 2? Then this book is for you! In this book, you will start with the role of Ansible in the DevOps module, which covers fundamental DevOps practices and how Ansible is leveraged by DevOps organizations to implement consistent and simplified configuration management and deployment. You will then move on to the next module, Ansible with DevOps, where you will understand Ansible fundamentals and how Ansible Playbooks can be used for simple configuration management and deployment tasks. After simpler tasks, you will move on to the third module, Ansible Syntax and Playbook Development, where you will learn advanced configuration management implementations, and use Ansible Vault to secure top-secret information in your organization. In this module, you will also learn about popular DevOps tools and the support that Ansible provides for them (MYSQL, NGINX, APACHE and so on). The last module, Scaling Ansible for the enterprise, is where you will integrate Ansible with CI and CD solutions and provision Docker containers using Ansible. By the end of the book you will have learned to use Ansible to leverage your DevOps tasks.

Preface

Installing Ansible


Ansible itself is cross-platform. The basic installation of the Ansible system is actually fairly easy. Before we can install it, we need to get the Ansible runtime packages. Ansible is available for consumption via the following online solutions:

  • Yum (Red Hat Linux-based distributions)
  • Apt (Debian)
  • Apt (Ubuntu)
  • Portage (Gentoo)
  • Pkg (FreeBSD)
  • macOS (dmg)
  • OpenCSW (Solaris)
  • Pacman (Arch Linux)
  • Pip (Python)
  • Tarball (Source)
  • Source (Source)

The following is a set of examples and command-line syntaxes for each of the listed options. These commands will help you get up-and-running with Ansible quickly (they are taken from the Ansible website).

Red Hat Enterprise Linux via Configuration Management

Installing Ansible on most popular Red Hat Enterprise Linux flavor distributions is quite easy. This can be accomplished as follows:

# NOTE: Before installing Ansible you may need to install the epel-release repo
# for RHEL or 
# Scientific Linux. Additional details on how to install EPEL can be found...
