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.

Developing Dockerized .NET Framework and .NET Core Applications

Docker is a platform for packaging, distributing, running, and managing applications. When you package your applications as Docker images, they all have the same shape. You can deploy, manage, secure, and upgrade them all in the same way. All Dockerized applications have the same requirements to run them: a Docker Engine running on a compatible operating system. Applications run in isolated environments, so you can host different application platforms and different platform versions on the same machine with no interference.

In the .NET world, this means you can run multiple workloads on a single Windows machine. They could be ASP.NET websites, or Windows Communication Foundation (WCF) apps running as .NET console applications or .NET Windows Services. In the previous chapter we looked at Dockerizing legacy .NET applications...
