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.

Chapter 5. Snapshot Your Cloud

In this chapter, we will cover the task of creating instance backups and/or snapshots using the native OpenStack capability built into the compute service (Nova). When adopting a true cloud approach, you will find a great use in snapshots versus backups, but it is still a good idea to understand both the capabilities and the proper use case for each. We will see how to manually create backups or snapshots first and then move on to creating a playbook with roles to fully automate it on a tenant level. In this chapter, we will cover the following points:

  • Define backups and snapshots

  • Creating backups and snapshots manually

  • Restoring an instance backup

  • Automation considerations

  • Coding the playbook and roles

  • Playbook and role review
