Building .NET Apps with Docker: A Developer’s Guide to Containerizing, Deploying, and Scaling .NET Applications with Docker

Rate this book
Build modern, portable, and production-ready .NET applications with the power of Docker. Building .NET Apps with Docker is a practical, hands-on guide for developers and DevOps engineers who want to harness containerization to streamline development, testing, deployment, and scaling of .NET applications across environments.

Whether you're developing with .NET Core or the latest .NET 7+ versions, Docker enables you to create consistent environments, reduce deployment friction, and scale services seamlessly. This book provides everything you need to know—from setting up your Docker workspace and writing Dockerfiles to deploying multi-container applications in the cloud.

Designed for developers at every level, this comprehensive resource dives deep into real-world use cases, sample code, and best practices. It starts with the fundamentals of Docker and builds up to advanced topics such as Docker Compose, secure deployments, CI/CD pipelines, and running containers in production environments like Azure, AWS, and Kubernetes.

You’ll learn how to containerize different types of .NET applications—console apps, ASP.NET Core web apps, microservices—and connect them with containerized databases and services. With step-by-step instructions, you’ll explore how to optimize image size, troubleshoot issues, write efficient Dockerfiles, and implement secure, scalable containers for real-world scenarios.
