Go (Golang) and Docker: Containerizing Applications

The book "Go (Golang) and Docker: Containerizing Applications" is a practical guide that bridges the gap between writing Go code and deploying it effectively in modern container environments. The author systematically takes the reader from basic Docker concepts to creating production-ready container solutions in Go.

What is this book about?

This is not just a Docker tutorial. It is a book about how to make the most of Go's capabilities (static compilation, small binary size, built-in concurrency) together with Docker to create fast, secure, and easily scalable applications. You will learn:

• Docker basics for Go developers: installation, images, containers, Dockerfile, working with registries.
• Creating minimal images: multi-stage builds, using scratch and distroless images to reduce size and improve security.
• Working with networks and data: configuring networks, mounting volumes, managing configuration via environment variables.
• Docker Compose in real projects: orchestrating multi-container applications (Go + database + cache + message queue).
• Logging and monitoring: centralized log collection, metrics, health checks.
• CI/CD and automation: integrating Docker into build and deployment pipelines.
• Container security: best practices, vulnerability scanning, resource limits.

Who is this book for?

The book will be useful for:

• Go developers who want to master containerization and DevOps practices.
• DevOps engineers transitioning to Go or wanting to deepen their understanding of containerization specifics for Go applications.
• Teams implementing microservice architecture in Go.
• Students and beginner developers familiar with Go basics who want to learn how to professionally deploy their projects.

What will you learn?

After reading, you will be able to:

• Create Docker images for Go applications smaller than 10 MB.
• Design multi-container application architecture using Docker Compose.
• Set up automated builds and deployments via CI/CD.
• Apply best practices for security and optimization.
• Confidently work with Docker in a production environment.

The book contains numerous practical examples, ready-to-use Dockerfiles and compose files, as well as real-world cases from the author's experience. All examples are available in a GitHub repository.

Note: The book assumes basic familiarity with the Go language (variables, functions, structures) and a general understanding of web development principles. Knowledge of Docker is not required — everything is explained from scratch.
