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

Summary


Having a rock solid monitor platform on your side is the key to cloud success (actually any production  systems success). Remember that 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. Please make sure to share any changes you make, remember Open Source is all about sharing. Before wrapping up this final chapter, let's take a moment to recap what we discussed. First we covered some monitoring tips and tricks. Then examined the OpenStack components worth monitoring. Next, we learned how to use Ansible ad hoc commands. We then transitioned into how to set up Nagios and import the custom plugins for the service checks. Finally, we developed Ansible playbooks and roles to automate the base installation of Nagios and NConf with customizing it to completely monitor an OpenStack cloud.  

Well ladies and gentleman, this has been fun and honestly a privilege to be allowed to share...
