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.

Once the playbook is executed, the output and end result will be two separate reports consisting of the information we learned in the previous section. These two reports will be saved in a directory determined by you for retrieval. At this point, you can literally send it to leadership and/or peers for review. In the next chapter, we will learn how you can take things further and directly email the report as an added bonus.

Very similar to the last chapter, we will break up the multiple tasks into separate roles to keep things organized. We will now review the six roles used to automate creating our cloud report.

The first role that we will create will include the tasks needed to set up the foundation for the cloud report. The name of the file will be main.yml located within the role directory named cloud-inventory/tasks. The contents of this file...
