Kubernetes in Action de Marko Luksa

Kubernetes in Action

Autor Marko Luksa
en Limba Engleză Paperback – 12 mai 2026

Prin parcurgerea acestui volum, veți reuși să implementați și să gestionați aplicații distribuite pe containere, pornind de la zero. Ne-a atras atenția structura progresivă a lucrării: nu sunteți aruncați direct în complexitatea orchestrației, ci începeți cu fundamentele tehnologiei Docker pentru a înțelege cum se construiesc imaginile ce vor rula ulterior în cluster. Apreciem modul în care Kubernetes in Action transformă concepte abstracte de rețea și infrastructură în elemente controlabile prin software, oferind cititorului control total asupra fluxului aplicațiilor.

Abordarea diferă de Kubernetes: Up and Running prin nivelul de detaliu oferit asupra mecanismelor interne — este mai puțin un manifest de arhitectură și mai mult un ghid de implementare aplicabil. În timp ce alte resurse se concentrează pe ecosistemul cloud, Marko Luksa pune accent pe operarea efectivă: cum să utilizați volume pentru stocare persistentă, cum să gestionați secretele prin ConfigMaps și cum să asigurați actualizări fără întreruperi (zero downtime). Reținem de asemenea capitolele avansate dedicate obiectelor StatefulSets, esențiale pentru rularea aplicațiilor care necesită persistența stării, un subiect adesea tratat superficial în literatura tehnică.

Fiecare etapă de învățare este susținută de exemple concrete de scalare automată și monitorizare, pregătind dezvoltatorii pentru provocările reale din producție. Stilul este tehnic și riguros, reflectând experiența autorului în cadrul Red Hat, ceea ce face ca această resursă să fie indispensabilă pentru înțelegerea modului în care Kubernetes acționează ca un sistem de operare pentru clustere de servere.

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 this book, 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.

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.
