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.

Targeting Multiple Distributions

As mentioned at the end of the last chapter, so far we have been targeting a single operating system with our playbook. While this is great if we are only going to run our playbook against CentOS 7 hosts, that might not always be the case.

In this chapter, we are going to look at adapting our WordPress installation playbook to target an Ubuntu 17.04 server instance.

In this chapter, we will:

  • Look at and implement core modules that are operating system-dependent
  • Discuss and apply best practices for targeting multiple distributions
  • See how we can target multiple hosts with an Ansible inventory
