Learn Ansible

By: Russ McKendrick

Overview of this book

Ansible has grown from a small, open source orchestration tool to a full-blown orchestration and configuration management tool owned by Red Hat. Its powerful core modules cover a wide range of infrastructures, including on-premises systems and public clouds, operating systems, devices, and services—meaning it can be used to manage pretty much your entire end-to-end environment. Trends and surveys say that Ansible is the first choice of tool among system administrators as it is so easy to use. This end-to-end, practical guide will take you on a learning curve from beginner to pro. You'll start by installing and configuring the Ansible to perform various automation tasks. Then, we'll dive deep into the various facets of infrastructure, such as cloud, compute and network infrastructure along with security. By the end of this book, you'll have an end-to-end understanding of Ansible and how you can apply it to your own environments.

The WordPress playbook

As you have already guessed, this is going to be extremely simple, as we already have written a playbook that deploys WordPress on a CentOS 7 host. In fact, all we need to do is copy the group_vars, roles folders, plus their contents, and also the site.yml file from the Chapter05/lemp folder in the repository and we are done.

This is one of the great advantages of using a tool such as Ansible: Write once and use often; the only change we will be making is the site.yml file when we add in the plays that deploy the software.
