Docker on Windows - Second Edition

By: Elton Stoneman

Overview of this book

Docker on Windows, Second Edition teaches you all you need to know about Docker on Windows, from the 101 to running highly-available workloads in production. You’ll be guided through a Docker journey, starting with the key concepts and simple examples of .NET Framework and .NET Core apps in Docker containers on Windows. Then you’ll learn how to use Docker to modernize the architecture and development of traditional ASP.NET and SQL Server apps. The examples show you how to break up legacy monolithic applications into distributed apps and deploy them to a clustered environment in the cloud, using the exact same artifacts you use to run them locally. You’ll see how to build a CI/CD pipeline which uses Docker to compile, package, test and deploy your applications. To help you move confidently to production, you’ll learn about Docker security, and the management and support options. The book finishes with guidance on getting started with Docker in your own projects. You’ll walk through some real-world case studies for Docker implementations, from small-scale on-premises apps to very large-scale apps running on Azure.

Breaking up monolithic applications

Traditional .NET web applications which rely on a SQL Server database can be migrated to Docker with minimal effort and without having to rewrite any application code. At this stage in my NerdDinner migration, I have an application Docker image and a database Docker image which I can reliably and repeatedly deploy and maintain. I also have some beneficial side effects.

Encapsulating the database definition in a Visual Studio project may be a new approach, but it adds quality assurance to database scripts and brings the schema into the code base, so it can be source-controlled and managed alongside the rest of the system. Dacpacs, PowerShell scripts, and Dockerfiles provide a new common ground for different IT functions. Development, operations, and database administration teams can work together on the same artifacts, using the same language...
