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.

Common OpenStack networking tasks


This section outlines common OpenStack networking tasks for quick reference only. For more details on using Neutron and how Neutron works – including details of when and where to use features such as Floating IPs and Routers, refer to Chapter 4, Neutron – OpenStack Networking.

Getting ready

Ensure that you have the OpenStack clients installed, as described in the first recipes in this chapter.

How to do it…

Carry out the following steps to create and modify networks in OpenStack:

Creating a network

There are usually two steps to create a network: creating the equivalent of an L2 network, followed by assigning a subnet (and details to it).

  1. First, create the network:

    openstack network create NETWORK_NAME
    
  2. Now create the subnet on this network:

    openstack subnet create SUBNET_NAME
        --network NETWORK_NAME--subnet-range CIDR
    
Creating a provider network (for use with Floating IPs)

To create a floating IP provider network, carry out the following commands. This command...
