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.

Yes! You just added a new OpenStack feature to your cloud. The flexibility and gained capability due to having multiple hypervisors as a part of your cloud is huge. Have fun with your new Docker compute node(s). But before concluding this chapter, let's take a moment to recap. We talked about the benefits of multiple hypervisor support and explained why using Docker as a hypervisor within OpenStack is a good use case. Next we manually walked through the setup process for adding Docker as a compute node (Docker and nova-docker driver). Lastly, we developed the Ansible playbook and role to automate adding the OpenStack feature of using Docker as a hypervisor to your cloud

The next chapter happens to be something that came in as a customer demand for a pretty large OpenStack cloud. There is no cloud operator out there who does not want to know or have a complete inventory of their cloud. Tracking resources, auditing users, and recapping network utilization are just a few things that...
