To all the people contributing to and being part of the open source community, building it one piece at a time, pushing its boundaries to make huge things.

Miguel Prez Colino is an experienced IT enthusiast with a clear orientation towards open source software and open standards. He has an extensive background in IT, from operations to the architecture of large deployments and from identifying and prototyping solutions to defining IT strategies. He has delivered large projects, including NATO interoperable command and control systems in defense, extensive large deployments in retail (>15,000 devices), and digital transformation in the finance sector.

Now, as part of the Cloud Platforms Business Unit of Red Hat, he works as a senior principal product manager building tools and defining methodologies to ease modernization and migration for customers, enabling the use of open source.

I want to thank my family, Sonia, Miguel, and Matilde, for the support and patience they have had with me during the months that I have been writing this book. Also, to Pablo Iranzo for being part of this adventure, and without whom we would not have been able to finish it. The whole Packt editing team has helped this first-time book authors immensely, as well as Scott and Gunnar, and I'd like to thank all of them for their contributions.

Pablo Iranzo Gmez is a software engineer whose Linux exposure began while studying physics, a period during which he was also involved in LUGs and some projects related to HPC clusters and system administration and consultancy.

Currently, he is a senior software engineer in Red Hat's SolEng department, focusing on OpenShift, with experience in consulting, cloud technical account management, OpenStack software maintenance in industries such as hospitality, retail, airlines, government, telco, 5G, partners, IT covering system administration and automation, virtualization, PaaS, support, the cloud, and so on, having a broad understanding of different views, needs, and risks across the industry.

Pablo was born in and lives in Valencia, Spain with his family.

I want to thank my wife, Eva, for all the support she offered me enrolling in this endeavor; to my kid, Pau, for all the happy moments that empowered me to drive forward; to Javier, for the countless hours of unconditional understanding; and I want also to say thanks to Miguel for offering me to help him with this; and, of course, the whole Packt team, who have helped, guided, and advised me during the whole process.

At Red Hat, Scott McCarty is a principal product manager for the container subsystem team, which enables key product capabilities in OpenShift Container Platform and Red Hat Enterprise Linux. His focus areas include container runtimes, tools, and images.

Scott is a social media start-up veteran, an e-commerce old-timer, and a weathered government research technologist, with experience across a variety of companies and organizations, from seven-person start-ups to 15,000-employee technology companies. This has culminated in a unique perspective on open source software development, delivery, and maintenance.

First, I would like to thank all of the people in the open source community that have contributed to creating code and documentation that helps us all achieve more. I would like to thank all of the people that build, distribute, document, and release Red Hat Enterprise Linux and bring it into environments that I never thought Linux could reach. Finally, I'd also like to thank all of the sysadmins out there that run all of this software to prevent downtime and move projects forward.

Matthew Bach is a senior specialist solutions architect at Red Hat, focused on the emerging technologies portfolio, such as OpenShift, middleware, and Ansible for DoD customers. He has been in the IT industry for over 17 years and is a 13-year US Navy information systems technician veteran. Matthew currently holds several Red Hat and other security-related certifications. When Matthew is not working with his customers on exciting technologies, he likes to spend time with his family, or on a mountain bike exploring the many trails Virginia has to offer.

To my wife, Ashley, with love: Thank you for your love, support, and patience through all of my endeavors in the endless pursuit of this career. I can think of no one I'd rather be with for the rest of my days than you and our five awesome kids.

To Maurice Carroll, thank you for the countless hours you spent cultivating an interest in computers with a teenage grandson, and my very first box of Red Hat Linux. You lit a spark in me that remains today.
