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

Coding the playbooks and roles


In this section, we will now create the playbooks and roles to set up the Admin region. We will also then outline the Ansible ad hoc commands needed to complete the other steps to set up the Active-Active clouds. When creating Ansible automation code for something of this nature, I typically like to create multiple tasks broken out into separate roles. This format allows you to be able to reuse roles created with other playbooks. We will end up with two playbooks and two roles to automate the steps to set up the Admin region. In the end, we will then recap the playbooks consuming those roles.

In the other half of this section, we will also outline the Ansible ad hoc commands needed to complete the other steps to set up the Active-Active clouds. You could surely collect the commands together to create playbooks and roles. I felt that this would be a few hundred lines of unnecessary code, so I went with drafting the commands and using search-and-replace.
