Kubernetes in Action

Summary

Kubernetes in Action is a comprehensive guide to effectively developing and running applications in a Kubernetes environment. Before diving into Kubernetes, the book gives an overview of container technologies like Docker, including how to build containers, so that even readers who haven’t used these technologies before can get up and running.

Purchase of the print book includes a free eBook in PDF, Kindle, and ePub formats from Manning Publications.

About the Technology

Kubernetes is Greek for “helmsman,” your guide through unknown waters. The Kubernetes container orchestration system safely manages the structure and flow of a distributed application, organizing containers and services for maximum efficiency. Kubernetes serves as an operating system for your clusters, eliminating the need to factor the underlying network and server infrastructure into your designs.

About the Book

Kubernetes in Action teaches you to use Kubernetes to deploy container-based distributed applications. You’ll start with an overview of Docker and Kubernetes before building your first Kubernetes cluster. You’ll gradually expand your initial application, adding features and deepening your knowledge of Kubernetes architecture and operation. As you navigate this comprehensive guide, you’ll explore high-value topics like monitoring, tuning, and scaling.

What’s Inside

• Kubernetes’ internals
• Deploying containers across a cluster
• Securing clusters
• Updating applications with zero downtime

About the Reader

Written for intermediate software developers with little or no familiarity with Docker or container orchestration systems.
