OpenStack Administration with Ansible 2 - Second Edition

Overview of this book

Most organizations are seeking methods to improve business agility because they have realized just having a cloud is not enough. Being able to improve application deployments, reduce infrastructure downtime, and eliminate daily manual tasks can only be accomplished through some sort of automation. We start with a brief overview of OpenStack and Ansible 2 and highlight some best practices. Each chapter will provide an introduction to handling various Cloud Operator administration tasks such as managing containers within your cloud; setting up/utilizing open source packages for monitoring; creating multiple users/tenants; taking instance snapshots; and customizing your cloud to run multiple active regions. Each chapter will also supply a step-by-step tutorial on how to automate these tasks with Ansible 2. Packed with real-world OpenStack administrative tasks, this book will walk you through working examples and explain how these tasks can be automated using one of the most popular open source automation tools on the market today.

Preface

Automation considerations


Automating this task was pretty straightforward and did not require any new framework decisions. All the other automation decisions we reviewed were previously carried over.

There was one area worth highlighting that you may too face when automating OpenStack tasks using the CLI. The default output of the CLI is pretty-printed (using the Python prettytable module) of which at times is not so pretty when you want to sort through the output. Some CLI commands allow specific formatting, but in the event the command does not allow it, you have other options. This is where the awk command becomes your very close ally again. In the next section, you will note the specific use of the awk command to filter out the values we need for the next task within the role.

It feels like we are ready to proceed now with creating our next playbook and role.
