Kotlin and Kubernetes: Microservices Development and Orchestration

The book "Kotlin and Kubernetes: Microservices Development and Orchestration" is a practical guide for developers who want to master building modern cloud applications using the Kotlin language and the Kubernetes platform. The author, Alexey Petrov, shares his experience in building fault-tolerant, scalable, and easily maintainable systems.

The book starts with the basics: you will learn why Kotlin is ideal for microservices architecture and how to set up a local development environment. Next, it covers creating REST services with Spring Boot and Ktor, containerizing them with Docker, and deploying them in a Kubernetes cluster. Special attention is paid to practical aspects: configuring Pod, Service, Deployment, traffic management via Ingress, working with ConfigMap and Secrets.

• Who this book is for: Java/Kotlin developers, DevOps engineers, team leads looking to transition to a microservices architecture. Basic knowledge of Kotlin and Linux is required.
• What you will learn:
  • How to design microservices in Kotlin using Spring Boot and Ktor
  • How to package applications into Docker images and manage them
  • How to set up a Kubernetes cluster for development and production
  • How to organize CI/CD with GitHub Actions and Helm
  • How to implement monitoring (Prometheus + Grafana) and logging (ELK)
  • How to test and debug microservices in Kubernetes
• Practical value: All code examples are available in a GitHub repository. You will be able to replicate the project from start to finish: from writing the first controller to deploying to the cloud.

The book contains over 20 practical exercises and 5 full-fledged projects. You will learn how to work with the Kubernetes API from Kotlin, use Coroutines for asynchronous processing, and configure autoscaling. A separate chapter is dedicated to security: access control, TLS certificates, secrets.

This is not just a reference book, but a step-by-step guide that will help you shorten the path from an idea to a working production solution. The book will be useful both for beginners in Kubernetes and for experienced developers wanting to master Kotlin in the context of cloud technologies.
