Rust and Kubernetes: Building Reliable Cloud Applications

The book "Rust and Kubernetes" is a practical guide for developers who want to master building high-performance and secure cloud applications in Rust within the Kubernetes environment. The author, Alexey Voronov, an experienced software engineer with many years of experience in Rust development and managing Kubernetes clusters, shares proven techniques and best practices.

What is this book about?

The book covers the full development cycle of Rust applications for Kubernetes:

• Rust basics: memory ownership, type system, asynchronous programming (tokio, async-std).
• Containerization of Rust applications: creating minimal Docker images (musl, scratch), multi-stage builds.
• Deployment in Kubernetes: Pods, Deployments, Services, ConfigMaps, Secrets.
• Microservice architecture: gRPC, REST API (actix-web, warp), inter-service communication.
• Advanced patterns: Operator pattern, Custom Resource Definitions (CRD), controllers.
• Security: secret management, RBAC, container security (seccomp, AppArmor).
• Monitoring and logging: Prometheus, OpenTelemetry, structured logging (tracing, slog).
• Testing: unit tests, integration tests, testing in Kubernetes (kind, k3s).

Who is this book for?

This book will be useful for:

• Python developers who want to learn Rust for building high-load services and understand how Rust complements Python in tasks requiring maximum performance and security.
• DevOps engineers who want to write their own tools and operators for Kubernetes in Rust.
• Backend developers striving to master modern approaches to building cloud microservices.
• Students and professionals interested in systems programming and cloud technologies.

What will you learn?

After reading the book, you will be able to:

• Create efficient and secure containers for Rust applications.
• Design and deploy microservices in Kubernetes from scratch.
• Use Rust to automate Kubernetes cluster management (operators, controllers).
• Configure monitoring, logging, and tracing for fault-tolerant systems.
• Apply security best practices at all stages — from code to production.

The book contains numerous ready-to-use code examples and practical exercises. Each chapter concludes with a summary and self-assessment questions. "Rust and Kubernetes" is your reliable guide to the world of modern cloud development in Rust.
