OpenStack Networking Essentials

By: James Denton, Derek Chamorro

Overview of this book

The OpenStack Networking API offers users the ability to create and manage both basic and complex network architectures that blend the virtual and physical network infrastructure. This book kicks off by describing various components of Openstack Neutron and installing Ubuntu OpenStack based on Canonical's process. Further on, you will use various methods to interface with Neutron to create and manage network resources. You will also get to grips with the relationship between ports, networks, and subnets through diagrams and explanations, and see how the logical components are implemented via plugins and agents. Moving forward, you will learn how virtual switches are implemented and how to build Neutron routers. You will also configure networks, subnets, and routers to provide connectivity to instances using simple examples. At the end, you will configure and manage security groups, and will observe how these rules translate to iptables rules on the host machines. By the end of the book, you will be able to build basic network architectures using Neutron networks and routers in no time.

Configure the answer file

Packstack relies on an answer file composed of key-value pairs that describe how various OpenStack and environment settings should be configured. The Packstack command has a parameter that can be passed to generate an initial answer file that can then be modified to suit your needs. You can also pass a file containing a subset of key-value pairs that can then be used during the installation process along with other defaults that Packstack specifies.

In your home directory, create a file named answers.cfg containing the following [general] header and subsequent key-value pairs as follows:

[general]

# Generic config options
CONFIG_UNSUPPORTED=n
CONFIG_DEBUG_MODE=n
CONFIG_PROVISION_DEMO...
