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.

Using the Neutron client


Neutron provides a command-line client for interfacing with its API. It is typically installed as part of the OpenStack distribution.

Note

The Neutron client can also be installed on your local workstation, provided you have a supported operating system. For more information on installing the client locally, refer to the OpenStack documentation at http://docs.openstack.org/user-guide/common/cli_install_openstack_command_line_clients.html.

When authenticated, Neutron commands can be run directly from the Linux command line, or the Neutron shell can be invoked by issuing the neutron command, like this:

[root@allinone ~(keystone_admin)]# neutron
(neutron)

The neutron shell provides commands that can be used to create, read, update, and delete the networking configuration within the OpenStack cloud. By typing ? or help within the Neutron shell, a list of commands available within the client can be found, as shown here:

Running the neutron help command from the Linux command...
