Cracking the Kubernetes Interview

Cracking the Kubernetes Interview

By: Viktor Vedmich, Alexander Dovnar

Overview of this book

In the high-stakes world of cloud-native technologies, Kubernetes technical interviews are notoriously challenging, and theory-heavy resources leave candidates unprepared for real-world scenarios. This guide by Viktor Vedmich and Alexander Dovnar, two seasoned professionals with decades of combined experience in DevOps, AWS, and Kubernetes architecture, bridges that gap to help you unlock actionable strategies and insights to excel in even the toughest interviews. Beginning with core concepts such as Pods and Services, the book guides you through scaling, networking, GitOps, and deployment strategies. You’ll explore advanced topics, including security, observability, monitoring, and troubleshooting, all framed in the context of real-world interviews. Each chapter includes practical scenarios and authentic questions that test both your understanding and problem-solving skills. Rather than relying on rote memorization, this guide helps you develop the depth and confidence expected of top-tier Kubernetes professionals. By the end of this hands-on journey, you'll be ready to take on roles from junior DevOps engineer to senior architect, equipped with the practical expertise needed to stand out in today’s competitive hiring process.

Storage: Persistence and CSI Drivers

Welcome to this chapter, where we delve into the critical aspects of managing data persistence and Container Storage Interface (CSI) drivers within Kubernetes environments. This chapter will equip you with the knowledge and skills to tackle storage-related questions during Kubernetes interviews. We’ll start by exploring the fundamentals of Kubernetes objects such as PersistentVolumes (PVs) and PersistentVolumeClaims (PVCs). These are essential components for ensuring data persistence in Kubernetes clusters. Additionally, we’ll delve into the complexity of StorageClasses and dynamic provisioning, empowering you to optimize storage resources effectively.

Furthermore, we’ll unravel the complexities of CSI drivers, providing insights into integrating external storage systems seamlessly with Kubernetes. We will deepen your understanding of storage persistence and CSI drivers, unlocking new opportunities for success in Kubernetes...
