DevOps for Kotlin Developers

The book "DevOps for Kotlin Developers" is a practical guide that bridges two worlds: modern Kotlin development and the DevOps culture. If you write server-side applications, Android projects, or microservices in Kotlin, but feel uncertain when setting up builds, deployments, or monitoring — this book is for you.

What is this book about?

The book is structured as an end-to-end example: from a simple Kotlin application to a fully automated production pipeline. You will learn how to:

• Configure Gradle Multi-Project for large Ktor and Spring Boot applications;
• Create CI/CD with GitHub Actions and GitLab CI, optimized for JVM builds;
• Containerize Kotlin services using Docker and reduce image sizes;
• Orchestrate microservices in Kubernetes (Deployments, Services, ConfigMaps);
• Implement monitoring and logging: Prometheus, Grafana, ELK for Kotlin applications;
• Automate testing (unit, integration, e2e) in the pipeline;
• Manage versions and releases using GitFlow and semantic versioning.

Who is this book for?

• Kotlin developers who want to independently deploy and maintain their projects;
• Backend engineers transitioning from Java to Kotlin and looking to master the modern DevOps stack;
• Team Leads and architects planning to implement automation in their team;
• DevOps engineers specializing in the JVM ecosystem and Kotlin.

What will you learn after reading?

• How to speed up Kotlin project builds by 2-3 times using Gradle Build Cache and configuration;
• How to set up zero-downtime deployment for Ktor services;
• How to write Helm charts for Kotlin microservices;
• How to integrate static code analysis (Detekt, Ktlint) into the pipeline;
• How to organize business metrics monitoring using Micrometer and Kotlin coroutines;
• How to avoid common mistakes when containerizing JVM applications (OutOfMemory, slow startup).

Why is this book important?

Kotlin is rapidly conquering the backend — Ktor, Spring Boot, Micronaut. But most DevOps tools and practices are described for Java, Python, or Go. This book fills the gap: all examples are written in Kotlin, taking into account the specifics of coroutines, serialization, and JVM optimizations. You won't just copy someone else's code — you will understand how to adapt any DevOps practice to your own project.

The book contains ready-made configurations that can be used immediately in real projects. Each chapter ends with a practical assignment to reinforce the material.

If you want your Kotlin applications to run stably, quickly, and without manual intervention — this book will become your desktop guide.
