Kotlin and Kubernetes: Microservices Development and Orchestration

Modern software development requires not only the ability to write quality code but also the skills to deploy and scale it effectively. The book "Kotlin and Kubernetes" is a practical guide that combines the power of the Kotlin language with the capabilities of one of the most popular container orchestration platforms — Kubernetes.

What is this book about?

The book will take you through the complete journey of creating a microservice application in Kotlin: from setting up a local environment and writing your first REST services to deploying in a production Kubernetes cluster. You will learn how to effectively use the Ktor and Spring Boot frameworks in a containerized environment, as well as how to configure auto-scaling, load balancing, and monitoring.

Who will benefit from this book?

• Kotlin developers who want to master Kubernetes and DevOps practices without switching to other languages.
• Java programmers transitioning to Kotlin who want to immediately gain skills in containerization and orchestration.
• DevOps engineers looking for examples of setting up CI/CD and monitoring for JVM applications.
• Architects designing highly resilient microservice systems.

What will you learn?

• Kotlin basics for backend development and creating REST APIs.
• Containerizing applications with Docker and writing efficient Dockerfiles for Kotlin.
• Kubernetes architecture: Pods, Deployments, Services, ConfigMaps, and Secrets.
• Configuring auto-scaling (HPA) and self-healing.
• Integrating with databases in the cluster (PostgreSQL, MongoDB).
• Building and deploying via GitHub Actions and GitLab CI/CD.
• Monitoring and logging with Prometheus, Grafana, and the ELK stack.
• Security: secret management, RBAC, network policies.

Why should you read it?

This book is not dry theory. Each chapter contains practical examples, ready-to-use configurations, and step-by-step instructions. You will be able to immediately apply the knowledge gained in your own projects. Special attention is given to common mistakes and how to avoid them.

If you want not just to write code in Kotlin but also to deliver it to users quickly, reliably, and with minimal cost — this book is for you. It will become your guide in the world of modern cloud development.
