Overview of this book

Docker is a platform for running server applications in lightweight units called containers. You can run Docker on Windows Server 2016 and Windows 10, and run your existing apps in containers to get significant improvements in efficiency, security, and portability. This book teaches you all you need to know about Docker on Windows, from 101 to deploying highly-available workloads in production. This book takes you on a Docker journey, starting with the key concepts and simple examples of how to run .NET Framework and .NET Core apps in Windows Docker containers. Then it moves on to more complex examples—using Docker to modernize the architecture and development of traditional ASP.NET and SQL Server apps. The examples show you how to break up monoliths into distributed apps and deploy them to a clustered environment in the cloud, using the exact same artifacts you use to run them locally. To help you move confidently to production, it then explains Docker security, and the management and support options. The book finishes with guidance on getting started with Docker in your own projects, together with some real-world case studies for Docker implementations, from small-scale on-premises apps to very large-scale apps running on Azure.

Summary

In this chapter, we covered three main topics:

Containerizing legacy .NET Framework applications so they are good Docker citizens and integrate with the platform for configuration, logging, and monitoring
Containerizing database workloads with SQL Server Express and the Dacpac deployment model, building a versioned Docker image that can run as a new database or upgrade an existing database
Extracting functionality from monolithic apps into separate containers, using ASP.NET Core and Windows Nano Server to package a fast, lightweight service that the main application consumes

You've learned how to use more images from Microsoft on Docker Hub and how to use Windows Server Core for full .NET applications, SQL Server Express for databases, and the Nano Server flavors of the .NET Core image.

In later chapters, I'll return to NerdDinner and continue to modernize...
