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.

Moving to the Cloud

In this chapter, we will move from using our local virtual machine to using Ansible to launch instances in a public cloud provider. For this chapter, we will be using DigitalOcean, and we are targeting this provider as it allows us to simply launch virtual machines and interact with them, without having too much configuration overhead.

We will then look at adapting our WordPress playbook so that it interacts with the newly launched instance.

In this chapter, we will cover the following topics:

  • A quick introduction to DigitalOcean
  • Launching instances in DigitalOcean
  • How to switch between running Ansible locally and remotely so we can deploy WordPress
