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.

Building Out a Cloud Network

Now that we have launched servers in DigitalOcean, we will move on to starting to look at launching services within Amazon Web Services (AWS).

Before we launch instances, we will need to create a network for them to be hosted in. This is called a VPC, and there are a few different elements we will need to bring together in a playbook to create one, which we will then be able to use for our instances.

In this chapter, we will:

  • Get an introduction to AWS
  • Cover what it is we are trying to achieve and why
  • Create a VPC, subnets, and routes—networking and routing
  • Create security groups—firewall
  • Create an Elastic Load Balancing (ELB)—load balancer
