Overview of this book

Network Automation Cookbook is designed to help system administrators, network engineers, and infrastructure automation engineers to centrally manage switches, routers, and other devices in their organization's network. This book will help you gain hands-on experience in automating enterprise networks and take you through core network automation techniques using the latest version of Ansible and Python. With the help of practical recipes, you'll learn how to build a network infrastructure that can be easily managed and updated as it scales through a large number of devices. You'll also cover topics related to security automation and get to grips with essential techniques to maintain network robustness. As you make progress, the book will show you how to automate networks on public cloud providers such as AWS, Google Cloud Platform, and Azure. Finally, you will get up and running with Ansible 2.9 and discover troubleshooting techniques and network automation best practices. By the end of this book, you'll be able to use Ansible to automate modern network devices and integrate third-party tools such as NAPALM, NetBox, and Batfish easily to build robust network automation solutions.

Deploying IGWs using Ansible

In this recipe, we will outline how to deploy Internet Gateways (IGWs) to our AWS VPCs using Ansible. IGWs are our exit points from our VPC to the internet in order to reach a public external destination. Since we are building a public-facing service, we need to have internet reachability from our VPC. This is accomplished by the IGW construct in the AWS cloud.

Getting ready

The Ansible control machine must have internet reachability and the VPCs must already be provisioned, as per the previous recipe.
