OpenStack Administration with Ansible

By: Walter Bentley

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. 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—Ansible. We will start with a brief overview of OpenStack and Ansible and highlight some best practices. Each chapter will provide an introduction to handling various Cloud Operator administration tasks such as creating multiple users/tenants, setting up Multi-Tenant Isolation, customizing your clouds quotas, taking instance snapshots, evacuating compute hosts for maintenance, and running cloud health checks, and a step-by-step tutorial on how to automate these tasks with Ansible.

Summary


See, now that was not so bad right? Ansible really does a great job in streamlining the efforts involved in automating OpenStack administrative tasks. You can now reuse that role over and over again, reducing the amount of time required to create users and tenants to single digit minutes. The time investment is well worth the benefits.

We covered how to create users and tenants in OpenStack via the API and CLI, gathered an understanding of basic automation considerations, and developed the Ansible playbook and role to automate the user and tenant creation.

With this great foundation, we are ready to move on to our next administrative task of customizing your cloud quotas. The next chapter will include a general understanding of what quotas are and how they are used in your OpenStack cloud. We will then transition into the exercise of creating quotas manually and then conclude with how to automate tasks with Ansible. See you in Chapter 4, Customizing Your Cloud's Quotas.
