Fundamentals of Kubernetes: A Step-By-Step Development and Interview Guide

Explore the world of Kubernetes and learn the concepts needed to develop, deploy, and manage applications on this container orchestrator. This step-by-step development guide is designed for application developers and support members aiming to learn Kubernetes and/or prepare for interviews. All the concepts in the book are presented in Q&A format, framing questions exactly the way they are asked in an interview, giving you a distinctive edge in interviews.

You'll start by understanding how application development and deployment have evolved over the decades leading up to containerization. You'll then dive deep into the Kubernetes concepts, understanding Kubernetes architecture, Kubernetes objects and workload resources, and how to exploit them to their full potential. You'll also understand Kubernetes deployment strategies and concepts related to rollout and rollback.

Moving on, you'll look at two very important aspects of any computing ecosystem: networking and storage. You will understand access control in Kubernetes and how to manage a Kubernetes cluster using probes, resource quotas, taints, and tolerations. You will also get an overview of Docker and go through some of Docker and Kubernetes best practices. Finally, you will learn about the kubectl command line tool.

• All about basic and advanced Kubernetes objects and workload resources
• Important concepts such as namespaces, selectors, annotations, and access control
• The Kubernetes networking and storage system
• How to manage a Kubernetes cluster with the help of probes, resource quotas, limits, and taints
• A summary of important kubectl commands (a cheat sheet)

Who This Book Is For

Application developers and technical managers--both on the development and support sides, beginner and intermediate Kubernetes practitioners and aspirants, and those preparing for Kubernetes interviews.
