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.

Chapter 7. Setting up Isolated Tenants

In this chapter, we will cover the concept of setting up multi-tenant isolation within your OpenStack cloud. Imagine the idea of being able to force strict segregation of your tenants and being able to assign each unshared resource. Well, out-of-the-box OpenStack offers this functionality. This can be accomplished using the combination of the identity, compute and block storage services. We will start this chapter explaining the building blocks of how to set up multi-tenant isolation. Once the concept is clear, we will review the steps required to automate this task. A special emphasis will be placed on explaining how automation of this level prevents incorrect configurations, missed steps, and provides an easily repeatable process. The chapter will end with us creating a fully working Ansible playbook, with roles to configure tenant creation with multi-tenant isolation enabled. In this chapter, we will cover the following topics:

  • Multi-tenant isolation...
