Rust and Kubernetes: Reliable Cloud Application Development

The book "Rust and Kubernetes" is a practical guide for developers who want to build reliable, high-performance, and secure cloud applications using the Rust language and the Kubernetes orchestrator. The author, Sergey Volkov, a senior engineer with 10 years of experience in cloud technologies, shares proven patterns and real-world cases from industrial development.

What this book is about

The book covers the full cycle of creating a microservice application in Rust — from architecture design to deployment in production. You will learn:

• How to use Rust's memory safety and its type system to build reliable cloud services
• Principles of building microservice architecture using tokio, actix-web, and tonic (gRPC)
• How to package Rust applications into minimal Docker containers (multistage build)
• Deployment and management in Kubernetes: Pods, Deployments, Services, ConfigMaps, Secrets
• Setting up CI/CD with GitHub Actions and GitLab CI for automatic build and deployment
• Monitoring and logging: integration with Prometheus, Grafana, and OpenTelemetry
• Ensuring security: resource limits, network policies, secrets, and Pod Security Standards

Who this book is for

The book will be useful for:

• Rust developers who want to go beyond CLI utilities and start building cloud services
• DevOps engineers looking to master Rust for creating fast and secure system components
• SRE specialists seeking an alternative to Go and Java for high-load services
• Architects planning a migration from a monolith to microservices using Rust

What you will get after reading

• A ready-made Rust microservice template with support for REST, gRPC, and asynchronous processing
• A set of Helm charts for deployment in Kubernetes with autoscaling and health checks
• An understanding of how Rust helps avoid a whole class of runtime errors (race conditions, null pointers)
• Practical skills for working with the Kubernetes API via the kube-rs crate
• Examples of performance optimization: 40% lower memory consumption compared to Java counterparts

All code examples are available in the GitHub repository and have been tested on current versions of Rust (1.70+) and Kubernetes (1.28+). The book is suitable both for beginners familiar with the basics of Rust and for experienced engineers who want to systematize their knowledge.

"Rust and Kubernetes" is a bridge between two powerful technologies. You will learn to build systems that don't crash, don't leak memory, and scale easily under any load.
