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


Here we are again, with yet another tool to add to our OpenStack administration toolbox. Having a quick cloud health report at your fingertips is extremely useful and valuable. Remember, this is only a starting point. I expect you to improve/customize it for your specific needs. I am looking forward to seeing all your great work in the future. Before wrapping up this final chapter, let's take a moment to recap. Together we reviewed some monitoring tips and tricks and examined the OpenStack components worth monitoring. Next, we learned how to use Ansible ad-hoc commands. Lastly, we developed an Ansible playbook and role to automate the generation of cloud reports.

Well ladies and gentleman, it has been fun and honestly a privilege to be allowed to share these automation examples with you. Do keep up the great work and also keep an eye out for future revisions as both OpenStack and Ansible continues to mature. I'm really looking forward to hearing your feedback and seeing how you took...
