OpenStack Administration with Ansible 2 - Second Edition

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. We start with a brief overview of OpenStack and Ansible 2 and highlight some best practices. Each chapter will provide an introduction to handling various Cloud Operator administration tasks such as managing containers within your cloud; setting up/utilizing open source packages for monitoring; creating multiple users/tenants; taking instance snapshots; and customizing your cloud to run multiple active regions. Each chapter will also supply a step-by-step tutorial on how to automate these tasks with Ansible 2. 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 on the market today.

Coding the playbooks and roles


We will now create a role that allows us to update a single and/or multiple project(s) quotas at one time. Updating a quota is a relatively simple two-step process. Step 1 is to record the tenant ID or user ID in which you wish to update the quota for. Then, step 2 is to actually update the quota.

Since we are only creating a role in this example, we can start with the main.yml file within the role directory named adjust-quotas/tasks. The contents at the beginning of this file will look like this:

--- 
 
- name: Adjust tenant quotas 
 command: openstack --os-cloud="{{ CLOUD_NAME }}" 
      quota set "{{ item.1 }}" "{{ item.0 }}" 
 with_together: 
  - "{{qoptions}}" 
  - "{{tenantname}}" 

Just like the manual commands we reviewed earlier in this chapter, you must supply the quota options you wish to adjust and the tenant name from the variable file we will review later. Again, we are using the with_together command to loop...
