C# (.NET) and Docker: Containerizing Applications

Modern software development is unthinkable without containerization. The book "C# (.NET) and Docker: Containerizing Applications" is a practical guide that will teach you how to package .NET applications into Docker containers, manage multi-container environments, and automate deployment processes.

What is this book about?

The book covers the full cycle of working with Docker in the .NET ecosystem: from installing tools to publishing ready-made images to a private or public registry. You will learn:

• How to create efficient Dockerfiles for ASP.NET Core, console, and background applications
• Principles of working with docker-compose for orchestrating multiple services (web API, databases, message queues)
• Image optimization: multi-stage builds, reducing size, layer caching
• Integrating Docker into CI/CD pipelines (GitLab CI, GitHub Actions, Azure DevOps)
• Container security: minimal privileges, vulnerability scanning, secret management
• Local development with hot reload and debugging inside a container

Who is this book for?

The material is intended for C# developers who are already familiar with the basics of the language and want to master modern application delivery methods. The book will be useful for:

• Backend developers striving to transition to a microservice architecture
• DevOps engineers responsible for the infrastructure of .NET projects
• Team Leads looking to standardize build and deployment processes within the team
• Students and entry-level specialists who want to acquire the in-demand skill of containerization

What will you learn after reading?

• Learn to write clean and efficient Dockerfiles for any type of .NET application
• Master launching multi-service projects using docker-compose
• Understand how to organize data storage (volumes) and configure network interactions
• Be able to automate image building and publishing via CI/CD
• Gain practical skills in working with logs, monitoring, and debugging containers

The book contains over 50 practical examples ready for use in real projects. All examples are relevant for .NET 6, 7, and 8, as well as the latest versions of Docker Desktop and Docker Engine. Start your journey to modern cloud development today!
