JavaScript (Node.js) and Kubernetes: A Practical Guide to Orchestration

Modern web development is unthinkable without containerization and orchestration. If you write in JavaScript and Node.js but feel uncertain at the word "Kubernetes" — this book will be your practical guide. "JavaScript (Node.js) and Kubernetes" is not another theory on cluster administration, but a focused guide for developers who want to learn how to package their applications into containers and manage them in a production environment.

What is this book about?

The book will take you through the entire journey: from creating a simple Node.js application and containerizing it with Docker to deploying it in a full-fledged Kubernetes cluster. You will learn how to set up a CI/CD pipeline, organize monitoring and logging, and how to scale the application under load. Special attention is paid to typical problems of Node.js developers: working with asynchrony in containers, state management, configuring health checks and graceful shutdown.

Who is this book for?

• Node.js developers who want to master DevOps practices without diving into Linux administration.
• Fullstack engineers who want to understand how their applications work in production.
• Tech leads planning a transition to a microservice architecture.
• DevOps engineers looking for clear examples in JavaScript, rather than Go or Java.

What will you learn?

• How to write a Dockerfile for a Node.js application (multi-stage build, layer optimization).
• How to create and configure a Kubernetes cluster (Minikube, kind, cloud solutions).
• How to describe Deployment, Service, Ingress, and ConfigMap for a Node.js service.
• How to configure automatic scaling (HPA) and load balancing.
• How to organize seamless deployment (rolling update, blue-green deployment).
• How to connect monitoring (Prometheus + Grafana) and centralized logging.
• How to work with databases and caches in Kubernetes (StatefulSet, PersistentVolume).
• How to write tests and implement CI/CD (GitHub Actions, GitLab CI).

Why should you read it?

This book is not about abstract concepts — it is about real tasks. Each chapter contains ready-to-use code examples, manifests, and scripts. You will not just read the theory, but will be able to immediately reproduce the described scenarios on your local cluster. By the end of the book, you will feel confident in the world of containers and will be able to independently design infrastructure for Node.js projects of any scale.

If you want to stop fearing Kubernetes and start using it as a powerful tool for your JavaScript applications — this book is for you.
