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!

The admin life

The admin user in our virtual appliance environment has the admin role on every project in the environment. Because we are logged in with a user who has the admin role, the Horizon dashboard exposes an Admin Panel Group, in addition to the Project Panel Group. Users who do not have the admin role will not see the admin panel group. See Figure 3.8.

Figure 3.8: By default, the Horizon dashboard admin panel group is only seen by users with the admin role

The admin panel group will allow the logged-in user to see all resources created in all projects across all domains. It's very important to not forget this when performing exam objectives. Some exam objectives may require access to the admin panel and we will explore this in upcoming chapters.
