Overview of this book

This book provides you with a specific strategy to pass the OpenStack Foundation’s first professional certification: the Certified OpenStack Administrator. In a recent survey, 78% of respondents said the OpenStack skills shortage had deterred them from adopting OpenStack. Consider this an opportunity to increase employer and customer confidence by proving you have the skills required to administrate real-world OpenStack clouds. You will begin your journey by getting well-versed with the OpenStack environment, understanding the benefits of taking the exam, and installing an included OpenStack All-in-One Virtual Appliance to work through objectives covered throughout the book. After exploring the basics of the individual services, you will be introduced to strategies to accomplish the exam objectives relevant to Keystone, Glance, Nova, Neutron, Cinder, Swift, Heat, and troubleshooting. Finally, you’ll benefit from the special tips section and a practice exam to put your knowledge to the test. By the end of the journey, you will be ready to become a Certified OpenStack Administrator!

$ cp openrc openrc-<project-name>

After making a copy of the original openrc file, use the editor of your choice to fill in the proper variables for project and tenant:

$ nano openrc-<project-name>

Ensure that you set both the OS_PROJECT_NAME and OS_TENANT_NAME variables:

export OS_PROJECT_NAME=<project-name>
