Overview of this book

<p>OpenStack is an open source cloud operating stack that was born from Rackspace and NASA and became a global success, developed by scores of people around the globe and backed by some of the leading players in the cloud space today.<br /><br />OpenStack Cloud Computing Cookbook, Second Edition will show you exactly how to install the components that are required to make up a private cloud environment. 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. Installation steps cover compute, object storage, identity, block storage volumes, image, horizon, software defined networking and DevOps tools for automating your infrastructure OpenStack Cloud Computing Cookbook, Second edition gives you clear step-by-step instructions to installing and running your own private cloud.</p>

Creating and managing keypairs


Keypairs refers to SSH keypairs and consist of two elements—a public key and a private key. Keypairs are used for access to our Linux hosts via SSH. The public portion of our keypair is injected into our instance at boot-time through a service known as cloud-init. Cloud-init can perform many tasks, one of which is managing this public keypair injection. Only this specific combination of the public and private key will allow us access to our instances.

Getting ready

To begin with, ensure that you are logged in to your Ubuntu client that has access to the Nova Client tools. This can be installed using the following commands:

sudo apt-get update
sudo apt-get –y install python-novaclient

And ensure you have set the following credentials set:

export OS_TENANT_NAME=cookbook
export OS_USERNAME=admin
export OS_PASSWORD=openstack
export OS_AUTH_URL=http://172.16.0.200:5000/v2.0/
export OS_NO_CACHE=1

How to do it...

To create a keypair, we use the nova keypair-add command...
