DevOps for Kotlin Developers: From Code to Production

Modern development in Kotlin requires not only knowledge of the language, but also an understanding of how to deliver code to the user quickly, reliably, and with minimal risks. The book "DevOps for Kotlin Developers" is a bridge between writing clean code and successfully deploying it to production. It is created specifically for Kotlin programmers who want to master DevOps practices without diving into excessive infrastructure theory.

What is this book about?

You will learn how to set up a complete delivery cycle for a Kotlin application: from the first commit to monitoring in production. The book covers the following key topics:

• Build automation and CI/CD. Configuring Gradle scripts, integrating with GitHub Actions and GitLab CI, creating pipelines for Kotlin projects.
• Containerization. Docker images for JVM applications, optimizing build size and time, working with Docker Compose.
• Orchestration. Deploying in Kubernetes: writing manifests, Helm charts, update strategies (rolling update, blue-green).
• Monitoring and logging. Prometheus + Grafana for Ktor/Spring Boot metrics, centralized log collection via Loki or ELK.
• Security. Secrets management, SAST scanners for Kotlin code, container security policies.

Who is this book for?

The book is intended for Kotlin developers of any level — from juniors just starting to understand deployment, to seniors looking to systematize their knowledge. If you write in Kotlin (Ktor, Spring Boot, Android) and want to manage infrastructure yourself or effectively collaborate with DevOps engineers — this publication is for you. Basic knowledge of Kotlin and JVM is assumed, but no experience with Docker or Kubernetes is required.

What will you gain after reading?

• Learn to write production-ready Dockerfiles for Kotlin applications.
• Be able to set up a CI/CD pipeline that automatically tests, builds, and deploys your project.
• Master basic and advanced techniques for working with Kubernetes.
• Understand how to monitor application performance and quickly find bottlenecks.
• Get ready-made templates and checklists for implementing DevOps practices in your team.

The book contains numerous practical examples, code listings, and step-by-step instructions. You won't just read theory — you'll be able to immediately apply the knowledge to real projects. The author, Alexey Voronov, has 10 years of experience in JVM development and 5 years in DevOps engineering, allowing him to speak the same language as both developers and infrastructure specialists.

"DevOps for Kotlin Developers" will become your desktop guide, helping to reduce the time from idea to release and make your applications more stable.
