OpenStack Administration with Ansible

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.

In this chapter, we will review a few possible approaches to adding new or existing features to your OpenStack cloud. The power of OpenStack is in the many capabilities that exist within the many OpenStack projects that make up the ecosystem. Some examples of these features can be seen in the different hypervisors supported by Nova, network plugins created for Neutron from many of the network device providers, and the storage drivers available that can be added to your Cinder configuration. Of course, there are many more features that can be easily enabled. Since we have to start somewhere, it felt best to cover one of the most asked-about features of Nova, the multiple hypervisor support. We will also go through the process of enabling a secondary hypervisor type. For our exercise here, we will cover the steps need to deploy Docker as a hypervisor on to your OpenStack cloud. I decided to pick a very popular hypervisor this time, in order to show relevance...
