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.

Introduction – using OpenStack


OpenStack can be interacted with in a number of ways – from using the Horizon (the OpenStack control panel) web interface to, the power of the command line to using third -party software, all of which are transparently integrated with OpenStack. In this chapter, we will introduce the OpenStack Command-Line Interface (CLI) and see how to configure it for use with your installation of OpenStack. The OpenStack command-line tools, like the vast majority of OpenStack, are written in Python. This means that there is a direct dependency on Python being available on the computer that will be running the clients.

When we interact with OpenStack, we are technically making REST API calls to the services that run the Service APIs (Application Programming Interfaces). A REST API defines a set of functions that developers can perform requests and receive responses via HTTP protocol such as GET and POST. The OpenStack command-line clients translate your intuitive commands...
