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.

Highly Available Cloud Deployments

Continuing with our AWS deployment, we will start to deploy services into the network we created in the previous chapter, and by the end of the chapter, we will be left with a highly available WordPress installation, which we will test by removing the instances while sending traffic to the site.

Building on top of the roles we created in the previous chapter, we will be doing the following:

  • Launching and configuring Amazon RDS (database)
  • Launching and configuring Amazon EFS (shared storage)
  • Launching and creating an Amazon Machine Image (AMI) (deploying the WordPress code)
  • Launching and configuring a launch configuration and autoscaling group (high availability)
