You will learn how to set up an environment that you manage just as you would a public cloud provider like Rackspace with the help of experienced OpenStack administrators and architects.<br /><br />We begin by configuring the key components such as identity, image compute, and storage in a safe, virtual environment that we will then build on this throughout the book. The book will also teach you about provisioning and managing OpenStack in the datacenter using proven DevOps tools and techniques.<br /><br />From installing or creating a sandbox environment using Vagrant and VirtualBox to installing OpenStack in the datacenter, from understanding logging to automating OpenStack installations, whatever level of experience or interest you have with OpenStack there is a chapter for you.

Configuring per tenant IP ranges for VLAN Manager


Tenants in OpenStack are a way of keeping user's cloud resources separate and are also referred to as projects within Nova Network. In a tenant, there are a number of images, instances, and its own network resources assigned to it. When we create a tenant, we assign it its own VLAN with its own private and public ranges. For example, we may wish to create a development tenancy that is separate from the performance testing tenancy and live tenancies.

Tip

Nova Networking uses the phrase project, which is synonymous to tenants created with keystone, as such the two terms are interchangeable when referring to projects.

Getting ready

To begin with, ensure you're logged in to the Controller server (our OpenStack VirtualBox Virtual Machine, controller, created in Chapter 3, Starting OpenStack Compute). If this was created using Vagrant you can log into this box using the following command:

vagrant ssh controller
