Kotlin and Docker: Application Containerization

The book "Kotlin and Docker: Application Containerization" is a practical guide that will help you master modern approaches to packaging, deploying, and scaling Kotlin applications using Docker. Whether you are writing microservices on Spring Boot, console utilities, or server applications on Ktor, this book will be your reliable companion in the world of containerization.

What is this book about?

The book covers the full cycle of working with Docker in the context of Kotlin development. You will start with the basics: what containers and images are, how to install Docker and set up your working environment. Then you will move on to building lightweight images for Kotlin applications, including layer optimization and the use of multi-stage builds. Special attention is given to working with Docker Compose for running multi-component systems, as well as integration with CI/CD pipelines (GitLab CI, GitHub Actions). The book covers real-world cases: cloud deployment, monitoring, logging, and troubleshooting.

Who is this book for?

• Kotlin developers who want to automate the deployment of their projects.
• DevOps engineers getting acquainted with Kotlin and wanting to understand its ecosystem.
• Students and beginner programmers learning modern development tools.
• Team leads and architects planning a transition to a container infrastructure.

What will you learn?

• How to write efficient Dockerfiles for Kotlin applications (Gradle, Maven, jar builds).
• How to reduce image size from 500 MB to 100 MB using multi-stage builds and Alpine distributions.
• How to organize work with databases, queues, and external services via Docker Compose.
• How to set up automatic builds and deployment via CI/CD.
• How to manage environment variables, volumes, and networks in Docker.
• How to debug containerized applications and analyze logs.

Why should you read it?

This book is written by a practitioner for practitioners. You will not find dry theory here — only proven recipes, code examples, and step-by-step instructions. Each chapter contains ready-to-use configurations that can be adapted to your project. After reading, you will be able to confidently containerize any Kotlin application, speeding up development and delivery processes.
