Tens of thousands of developers have learned how to develop and run a Kubernetes environment from Kubernetes in Action. This new second edition updates the definitive guide with new, in-depth coverage of the Kubernetes architecture, including the Kubernetes API, and then ins-and-outs of application deployment.

As more and more applications are created using cloud-native and container-based architectures, Kubernetes has become an essential tool for modern developers to master. This book lays out a complete introduction to container technologies and containerized applications along with practical tips for efficient deployment and operation. From building your first cluster, you’ll steadily expand your initial application, adding features and deepening your knowledge of Kubernetes architecture.

In it, you’ll find:

• Up and running with Kubernetes
• Deploying containers across a cluster
• Securing clusters
• Updating applications with zero downtime

About the technology

Kubernetes is the de facto standard for deploying containerized distributed applications. This powerful platform acts as an operating system for containers and clusters, reducing the need to micro-manage network and server infrastructure. Used daily by millions of developers, administrators, and architects, Kubernetes is must-know enterprise software.

About the book

Kubernetes in Action, Second Edition is the definitive guide to developing and deploying software with Kubernetes. Built on the bestselling first edition, this end-to-end revision provides up-to-date coverage on structuring Kubernetes-based applications and taking advantage of the Kubernetes API. You’ll also discover other key topics like configuration, attaching storage, scaling, and zero-downtime maintenance.

What's inside

• Up and running with Kubernetes
• Deploying containers across a cluster
• Updating applications safely

About the reader

Written for intermediate software developers. No prior experience with Kubernetes or containers is required.
