Preparing for the Certified OpenStack Administrator Exam

By: Matt Dorn

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!

Summary

Great! We just completed the Heat exam objective section of our COA prep. Remember that you can complete Horizon objectives on both the dashboard and CLI, but updating an existing stack is much easier on the CLI thanks to the --existing flag. Don't forget to always try to use UUIDs of virtual resources for Heat parameters. There may be multiple resources with the same name and UUIDS allow us to be specific. Do not be overly concerned with building Heat templates from scratch or overly complex Heat template scenarios. If you can kick a stack and provide the appropriate parameters, you'll be good to go! Now that we have completed all service-related objectives in the exam, let's move on to the final section: troubleshooting!
