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 3. Creating Multiple Users/Tenants

We have finally arrived at the part of the book where we can put our hands on the keyboard and create our very first OpenStack administration playbook. The task of creating users and tenants for your OpenStack cloud is literally one of the first steps in setting up your cloud for user consumption. So, let's get started. We will see how one would manually do this first and then transition into creating a playbook with roles to fully automate it. While creating the playbook/role, I will try to highlight any possible concerns and flexible ways in which you can accomplish this using Ansible. We will cover the following:

  • Creating users and tenants

  • Automation considerations

  • Coding the playbook and roles

  • The playbook and role review
