Kubernetes Cookbook

Kubernetes is the de facto standard for container orchestration and distributed applications management across a microservices framework. With this practical cookbook, you’ll learn hands-on Kubernetes recipes for automating the deployment, scaling, and operations of application containers across clusters of hosts.

In this fully updated second edition, Sameer Naik, Sébastien Goasguen, and Jonathan Michaux from TriggerMesh provide a problem-solution-discussion format with easy lookups to help you find the detailed answers you need—fast. Kubernetes lets you deploy your applications quickly and predictably, so you can efficiently respond to customer demand. This cookbook delivers the essential knowledge that developers and system administrators need to get there.

Recipes in this cookbook focus on:

• Creating a Kubernetes cluster
• Using the Kubernetes command-line interface
• Managing fundamental workload types
• Working with services
• Exploring the Kubernetes API
• Managing stateful and non-cloud-native apps
• Working with volumes and configuration data
• Cluster-level and application-level scaling
• Securing your applications
• Monitoring and logging
• Maintenance and troubleshooting

Welcome to Kubernetes Cookbook, and thanks for choosing it! With this book, we want to help you solve concrete problems around Kubernetes. We’ve compiled more than 100 recipes covering topics such as setting up a cluster, managing containerized workloads using Kubernetes API objects, using storage primitives, configuring security, and plenty more. Whether you are new to Kubernetes or have been using it for a while, we hope you’ll find something useful here to improve your experience and use of Kubernetes.

Who Should Read This Book

This book was written for anyone who belongs somewhere in the DevOps spectrum. You might be an application developer who is required to occasionally interact with Kubernetes, or a platform engineer creating reusable solutions for other engineers in your organization, or anywhere in between. This book will help you navigate your way successfully through the Kubernetes jungle, from development to production. It covers core Kubernetes concepts as well as solutions from the broader ecosystem that have almost become de facto standards in the industry.

Why We Wrote This Book

Collectively, we have been part of the Kubernetes community for many years and have seen the many issues beginners and even more advanced users run into. We wanted to share the knowledge we’ve gathered running Kubernetes in production, as well as developing on and in Kubernetes—​i.e., contributing to the core codebase or the ecosystem and writing applications that run on Kubernetes. It made perfect sense to work on the second edition of this book, considering that Kubernetes adoption has continued to grow in the years since the first edition of the book was published.
