Through fast-paced chapters, you'll unlock the benefits of GitOps for flexible configuration management, monitoring, robustness, multi-environment support, and discover tricks and tips for managing secrets in the unique GitOps fashion. GitOps and Kubernetes is half reference, half practical tutorial for operating Kubernetes the GitOps way. Table of Contents PART 1 - OVERVIEW Introducing Kubernetes First steps with Docker and Kubernetes PART 2 - CORE CONCEPTS Pods: running containers in Kubernetes Replication and other controllers: deploying managed pods Services: enabling clients to discover and talk to pods Volumes: attaching disk storage to containers ConfigMaps and Secrets: configuring applications Accessing pod metadata and other resources from applications Deployments: updating applications declaratively StatefulSets: deploying replicated stateful applications PART 3 - BEYOND THE BASICS Understanding Kubernetes internals Securing the Kubernetes API server Securing cluster nodes and the network Managing pods' computational resources Automatic scaling of pods and cluster nodes Advanced scheduling Best practices for developing apps Extending Kubernetes About the Author Marko Luksa is an engineer at Red Hat working on Kubernetes and OpenShift. 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.

As you navigate this comprehensive guide, you'll explore high-value topics like monitoring, tuning, and scaling. You'll gradually expand your initial application, adding features and deepening your knowledge of Kubernetes architecture and operation. You'll start with an overview of Docker and Kubernetes before building your first Kubernetes cluster. About the Book Kubernetes in Action teaches you to use Kubernetes to deploy container-based distributed applications. Kubernetes serves as an operating system for your clusters, eliminating the need to factor the underlying network and server infrastructure into your designs.

The Kubernetes container orchestration system safely manages the structure and flow of a distributed application, organizing containers and services for maximum efficiency. About the Technology Kubernetes is Greek for 'helmsman,' your guide through unknown waters. Purchase of the print book includes a free eBook in PDF, Kindle, and ePub formats from Manning Publications. 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. Summary Kubernetes in Action is a comprehensive guide to effectively developing and running applications in a Kubernetes environment.
