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.

Instrumentation in Dockerized applications

Debugging your app is what you do when the logic doesn't work as expected and you're trying to track down what's going wrong. You don't debug in production, so you need your app to record its behavior to help you trace any problems that occur.

Instrumentation is often neglected, but it should be a crucial component of your development. It's the best way to understand the health and activity of your app in production. Running your app in Docker provides new opportunities for centralized logging and instrumentation so that you can get a consistent view across the different parts of your application, even if they use different languages and platforms.

Adding instrumentation to your containers can be a straightforward process. Windows Server Core containers are already collecting lots of metrics in Windows performance...
