Rust and Docker: Containerizing Applications

The book "Rust and Docker: Containerizing Applications" is a practical guide for developers seeking to master the modern approach to deploying fast and reliable Rust applications in a container environment. The author, Alexey Voronov — an experienced software engineer and DevOps architect — shares proven techniques and best practices for integrating two powerful technologies.

What is this book about?

The book covers the full lifecycle of working with Rust and Docker: from writing your first container to deploying to production. You will learn how to create minimal and efficient images, manage dependencies, configure multi-container applications using Docker Compose, and automate building and testing via CI/CD. Special attention is given to security, performance, and reducing the final image size — critically important aspects for Rust projects.

Who is this book for?

• Rust developers who want to master containerization and simplify the deployment of their projects.
• DevOps engineers familiar with Docker who wish to gain a deeper understanding of working with binary Rust applications.
• Backend programmers building high-load microservices and striving for maximum isolation and deployment speed.
• Students and aspiring engineers who want to gain practical skills with a modern technology stack.

What will you learn from the book?

• How to create an efficient Dockerfile for a Rust project using multi-stage builds.
• Secrets to reducing container size to 10 MB and below — through static linking and Alpine/scratch images.
• How to organize building and testing of Rust code in CI/CD pipelines (GitHub Actions, GitLab CI).
• Principles of working with Docker Compose for microservice architecture on Rust.
• How to securely store secrets and manage configuration in containerized applications.
• Methods for profiling and debugging Rust applications inside a container.
• Practical examples: REST API, WebSocket server, CLI utility in a container.

The book contains numerous ready-to-use code examples, checklists, and step-by-step instructions. All examples are tested on current versions of Rust (1.75+) and Docker (24+). After reading, you will be able to confidently package any Rust projects into containers, reducing deployment time and increasing application stability.

Whether you are building microservices, CLI utilities, or web applications — this book will be your reliable companion on the path to professional containerization with Rust.
