OpenStack is the open source software for building public and private clouds, and privately hosted software-defined infrastructure services. It is a global open source success and is developed and supported by thousands of people around the globe and backed by leading players in the cloud space today. This book is specifically designed to quickly help you get up to speed with OpenStack and give you the confidence and understanding to roll it out into your own datacenters. This book covers an installation of OpenStack using Ansible, into your datacenters, in addition to providing steps for running under so that you can quickly gain the knowledge needed to install and operate OpenStack today. This book has been written by four principal level OpenStack engineers and architects from Rackspace, and it covers a wide range of topics that help you install and configure your OpenStack environments. This book will guide you in the following things:
How to install and configure all of the core components of OpenStack using OpenStack-Ansible
How to master the complete private cloud stack, from scaling out compute resources to managing object storage services for highly redundant, highly available storage
Examples of using Heat and Ansible to orchestrate workloads running on OpenStack
Practical, real-world examples of each service built upon in each chapter, allowing you to progress with the confidence that they will work in your own environments
This book gives you clear, step-by-step instructions to install and run your own private cloud successfully. It is full of practical and applicable recipes that enable you to use the latest capabilities of OpenStack and implement them.
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.

There are a number of text conventions used throughout this book.
CodeInText: Indicates code words in text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles. Here is an example: Configuration of the host’s networking, on a Ubuntu system, is performed by editing the /etc/network/interfaces file.A block of code is set as follows:
# Shared infrastructure parts
shared-infra_hosts:
controller-01:
ip: 172.29.236.110
controller-02:
ip: 172.29.236.111
controller-03:
ip: 172.29.236.112
# Compute Hosts
compute_hosts:
compute-01:
ip: 172.29.236.113
compute-02:
ip: 172.29.236.114When we wish to draw your attention to a particular part of a code block, the relevant lines or items are set in bold:
# Shared infrastructure parts shared-infra_hosts: controller-01: ip: 172.29.236.110 controller-02: ip: 172.29.236.111 controller-03: ip: 172.29.236.112 # Compute Hosts compute_hosts: compute-01: ip: 172.29.236.113 compute-02: ip: 172.29.236.114
Any command-line input or output is written as follows:
cd /opt/openstack-ansible/scripts
Bold: Indicates a new term, an important word, or words that you see on the screen, for example, in menus or dialog boxes, also appear in the text like this. Here is an example: "Next choose Advanced system settings from the menu on the left."
In this book, you will find several headings that appear frequently (Getting ready, How to do it..., How it works..., There’s more..., and See also).
To give clear instructions on how to complete a recipe, use these sections as follows:
This section tells you what to expect in the recipe and describes how to set up any software or any preliminary settings required for the recipe.
This section usually consists of a detailed explanation of what happened in the previous section.
This section consists of additional information about the recipe in order to make you more knowledgeable about the recipe.
