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


It's nice to have completed yet another chapter covering real-life OpenStack administrative duties. The more you create playbooks and roles, the faster you will be able to create a new code just by simply reusing the code created earlier for other purposes. Before this book is over, you will have a nice collection of playbooks/roles to reference for future Ansible automation.

Taking a moment to recap this chapter, you will recall that we covered what an instance migration is and why you might want to use this functionality, we reviewed the two possible migration methods—traditional and live-migration—learned how to manually migrate an instance, and also a work-around on how to use traditional migration to migrate an instance to a specific compute node. Lastly, we created the Ansible playbook and role to automate that work-around approach.

The next chapter is near and dear to my heart, as it required me to spend hours perfecting it for a customer I was working with at the time. It even...
