DevOps for Rust Developers: CI/CD, Containerization, and Deployment

The book "DevOps for Rust Developers" is a practical guide that bridges the gap between writing Rust code and reliably deploying it to production. You will learn how to turn a raw project into a polished service that is easy to scale and maintain.

What is this book about?

We cover the full lifecycle of a Rust application: from repository setup to production monitoring. Special emphasis is placed on tools that are most effective in the Rust ecosystem:

• CI/CD pipelines — setting up GitHub Actions and GitLab CI for automatic building, testing, and publishing crates;
• Containerization — creating minimal Docker images for Rust (multistage build, distroless, scratch);
• Orchestration — deploying to Kubernetes considering the specifics of Rust binaries (low memory consumption, fast startup);
• Monitoring and logging — integration with Prometheus, Grafana, OpenTelemetry, and structured logging via tracing and log;
• Configuration management — working with environment variables, Vault, secrets, and feature flags.

Who is this book for?

The book is aimed at intermediate and advanced Rust developers who:

• Already write in Rust but want to automate build and delivery processes;
• Plan to move their applications to the cloud or their own servers;
• Want to learn DevOps best practices specifically in the context of Rust (as opposed to general DevOps books);
• Are looking for ways to reduce container size and speed up build time.

What will you learn?

• How to set up smart dependency caching so CI builds take <30 seconds;
• How to create a Docker image weighing less than 5 MB for a Rust binary;
• How to organize zero-downtime deployment for high-load microservices;
• How to write custom metrics for monitoring Rust code performance;
• How to use cross-compilation and multi-architecture images.

All code examples are available in the repository and ready to use. The book is written in a lively style, without excessive theory — only practice, tested on real projects.

Ideal for those who want their Rust applications to run stably, quickly, and without surprises.
