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.

Hardening Your Servers Using Ansible and OpenSCAP

One of the advantages of using an orchestration and configuration tool like Ansible is that it can be used to generate and deploy a complex set of configurations in a repeatable task across many hosts. In this chapter, we are going to a look at a tool that actually generates the configuration for you to then apply.

In this chapter, we will learn how to harden a Red Hat-based CentOS 7.5.1804 host using Ansible and OpenSCAP.
