This book is aimed at system administrators and technical architects moving from a virtualized environment to cloud environments who are familiar with cloud computing platforms. Knowledge of virtualization and managing Linux environments is expected. Prior knowledge or experience of OpenStack is not required, although beneficial.

Chapter 1, Installing OpenStack with Ansible, walks you through a practical installation of OpenStack using OpenStack-Ansible.

Chapter 2, The OpenStack Client, shows you how to install the tools needed to operate OpenStack, as well as providing a quick reference to commonly used commands.

Chapter 3, Keystone – OpenStack Identity Service, explains how to use Keystone to configure and maintain services and projects within OpenStack.

Chapter 4, Neutron – OpenStack Networking, covers the introduction and use of the software-defined networking service and its plugins.

Chapter 5, Nova – OpenStack Compute, works through a number of examples of running and operating virtual machine instances to run your applications.

Chapter 6, Glance – OpenStack Image Service, explores the use of the machine images that are used to spawn instances.

Chapter 7, Cinder – OpenStack Block Storage, presents how to work with block storage volumes to attach to your instances.

Chapter 8, Swift – OpenStack Object Storage, depicts how to use the highly available and redundant object storage service.

Chapter 9, OpenStack Orchestration Using Heat and Ansible, discusses how to begin orchestrating your workloads within OpenStack using both Heat and Ansible.

Chapter 10, Using OpenStack Dashboard, shows you how to navigate the Horizon user-interface dashboard.

To use this book, you will need access to computers or servers that have hardware virtualization capabilities. Familiarity of Linux and accessing Linux servers using SSH is expected.

To set up the lab environment described at the end of Chapter 1, Installing OpenStack with Ansible, you will need to install and use Oracle’s VirtualBox and Vagrant. You can access details of how to set up your computer using VirtualBox and Vagrant by visiting https://github.com/OpenStackCookbook/vagrant-openstack.

There are additional recipes to get you started with the lab environment available at http://www.openstackcookbook.com. Refer to this website for information on installation of supporting software such as MariaDB/MySQL. More information can be found at http://bit.ly/OpenStackCookbookPreReqs.
