C# (.NET) and Docker: Application Containerization

Modern software development is unthinkable without containerization. Docker has become the de facto standard for packaging, delivering, and running applications. If you write in C# and work with the .NET ecosystem, this book will become your indispensable guide to mastering container technologies.

What is this book about?
This is a practical guide that will take you step by step from the basic concepts of Docker to creating production-ready solutions in C#. You will learn how to:

• Install and configure Docker for .NET development
• Write efficient Dockerfiles for ASP.NET Core applications
• Manage multi-layer images and minimize their size
• Work with docker-compose for orchestrating microservices
• Integrate containerization into CI/CD pipelines (GitHub Actions, GitLab CI)
• Deploy .NET applications in Kubernetes
• Ensure container security and monitoring

Who is this book for?
The book will be useful for:

• C# (.NET) developers who want to master modern deployment approaches
• DevOps engineers looking to deepen their knowledge of the .NET ecosystem specifics
• Team Leads and architects planning a transition to a microservices architecture
• Students and entry-level specialists striving to gain in-demand skills

What will you learn?
After reading, you will be able to:

• Containerize existing .NET applications without changing code
• Design microservices architecture considering Docker best practices
• Configure automatic build and publishing of images
• Work with volumes, networks, and environment variables in the .NET context
• Diagnose and optimize container performance

Each chapter contains real code examples, ready-made Dockerfiles, and architectural solution diagrams. You won't just read theory — you will be able to immediately apply the knowledge gained in practice. The book is written in a lively language, with complex concepts explained through analogies and visual diagrams.

Why choose this book?
The author is a practicing developer with 10 years of experience in .NET and DevOps. All examples are tested on current versions of .NET 8/9 and Docker. The book is regularly updated to keep up with the latest changes in the ecosystem.
