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, youll steadily expand your initial application, adding features and deepening your knowledge of Kubernetes architecture. In this book, youll 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. Youll 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 with zero downtime About the reader Written for intermediate software developers. No prior experience with Kubernetes or containers is required. About the author Marko Luka is an independent software engineer specializing in cloud-native technologies. Kevin Conner is a Senior Principal Software Engineer at Red Hat, focussed on cloud technologies and software supply chain security.

SummaryKubernetes 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 TechnologyKubernetes 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 BookKubernetes 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.
