Rust and Docker: Containerizing Applications

The book "Rust and Docker: Containerizing Applications" is a practical guide for developers who want to master modern approaches to packaging, delivering, and deploying Rust services using Docker. The author, Alexey Kuznetsov, shares his experience in creating production-ready containers that are fast, secure, and stable.

What is this book about?

The book covers the full lifecycle of a Rust application in a container environment: from writing code to deploying in the cloud. You will learn:

• How to properly build multi-stage Docker images for Rust (multi-stage builds) — from a base image to a minimal final layer.
• Ways to optimize image size: using scratch, alpine, static linking, removing unnecessary dependencies.
• Configuring Docker Compose for local development and testing of microservices in Rust.
• Integration with CI/CD (GitHub Actions, GitLab CI) — automated building, testing, and publishing of images.
• Security: vulnerability scanning, minimal privileges, process isolation.
• Working with networks, volumes, and environment variables in Rust containers.

Who is this book for?

• Rust developers who want to package their applications in Docker and simplify deployment.
• DevOps engineers implementing containerization for high-performance services.
• Team leads and architects making decisions about project stack and infrastructure.
• Anyone already familiar with the basics of Rust and Docker but looking to deepen their knowledge of using them together.

What will you learn after reading?

• Create Docker images smaller than 10 MB for Rust applications.
• Set up hot reload in containers for rapid development.
• Implement graceful shutdown and signal handling in Rust services inside Docker.
• Use Docker for unit and integration testing of Rust code.
• Deploy containerized applications to Kubernetes (basics of orchestration).

The book contains many ready-made examples, Dockerfiles, and scripts that can be immediately adapted for your projects. All examples have been tested with current versions of Rust (1.70+) and Docker (24+).

Ideal for those who want to write fast code and deliver it just as quickly.
