Ansible 2 Cloud Automation Cookbook

By: Aditya Patawari, Vikas Aggarwal

Overview of this book

Ansible has a large collection of inbuilt modules to manage various cloud resources. The book begins with the concepts needed to safeguard your credentials and explain how you interact with cloud providers to manage resources. Each chapter begins with an introduction and prerequisites to use the right modules to manage a given cloud provider. Learn about Amazon Web Services, Google Cloud, Microsoft Azure, and other providers. Each chapter shows you how to create basic computing resources, which you can then use to deploy an application. Finally, you will be able to deploy a sample application to demonstrate various usage patterns and utilities of resources.

Using dynamic inventory

As we have established in previous chapters, managing a text-based inventory can be a pain. There are chances that a manually managed inventory can consist of stale data that can impact our applications. Ansible provides dynamic inventory to address this.

Ansible's GitHub repository has scripts for various infrastructure providers, including a script for DigitalOcean (https://github.com/ansible/ansible/blob/devel/contrib/inventory/digital_ocean.py).

How to do it...

We need to download this script and configure it to use our credentials:

$ curl https://github.com/ansible/ansible/raw/devel/contrib/inventory/digital_ocean.py > digital_ocean.py
$ chmod +x digital_ocean.py
$ curl https://raw.githubusercontent...
