Overview of this book

This is the fourth edition of the industry-acclaimed OpenStack Cloud Computing Cookbook, created by four recognized OpenStack experts. It has now been updated to work with the latest OpenStack builds, using tools and processes based on their collective and vast OpenStack experience. OpenStack Open Source Cloud software is one of the most used cloud infrastructures to support a wide variety of use cases, from software development to big data analysis. It is developed by a thriving community of individual developers from around the globe and backed by most of the leading players in the cloud space today. We make it simple to implement, massively scalable, and able to store a large pool of data and networking resources. OpenStack has a strong ecosystem that helps you provision your cloud storage needs. Add OpenStack's enterprise features to reduce the cost of your business. This book will begin by showing you the steps to build up an OpenStack private cloud environment using Ansible. You'll then discover the uses of cloud services such as the identity service, image service, and compute service. You'll dive into Neutron, the OpenStack Networking service, and get your hands dirty with configuring networks, routers, load balancers, and more. You’ll then gather more expert knowledge on OpenStack cloud computing by managing your cloud's security and migration. After that, we delve into OpenStack Object storage and you’ll see how to manage servers and work with objects, cluster, and storage functionalities. Finally, you will learn about OpenStack dashboard, Ansible, Keystone, and other interesting topics.

Working with volume snapshots


Cinder volume snapshots provide a way to nondisruptively copy a volume; allowing for in-situ volume backups to be taken. It also enables more advanced backup features and provides the ability to boot an instance from a given snapshot or from a point in time.

In this section, we will show you how to create a snapshot, mount a volume based off a snapshot, refresh a snapshot, and delete a given snapshot.

Getting ready

To work with Cinder volume snapshots, you will need the following:

  • The openstack command-line client

  • An openrc file with appropriate credentials for the environment

  • The name or ID of the volume to delete

How to do it…

To create a snapshot, the volume must be first detached from an instance:

  1. First, list your current volumes:

    If the volume you wish to snapshot has a status of in-use, you will need to detach it using the instructions in the Detaching volumes from an instance recipe earlier in this chapter.

  2. As our volume is the correct state of available, we...
