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.

Modernizing legacy applications

Breaking out backend features is a great way to start decomposing legacy monoliths. Adding a message queue to your deployment makes this a pattern you can repeat with any feature that would benefit from being asynchronous. There are other patterns for breaking down monolithic apps. We can really start to modernize NerdDinner if we expose a REST API and move to a modular UI for the frontend, with a reverse proxy to route between different components. We can do all of this with Docker.

Adding a REST API to expose data

Legacy apps often end up as stores of data that can't be accessed outside the app. The data would be valuable to other applications or to business partners if it was accessible...
