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.

Running a message queue in Docker


The web application now publishes messages, and a handler listens for them, so the final component I need is a message queue to connect the two. Queues need the same level of availability as the rest of the solution, so they're good candidates for running in Docker containers. In a distributed solution deployed on many servers, the queue can be clustered across multiple containers for performance and redundancy.

Your choice of messaging technology depends on the features you need, but there are plenty of options with .NET client librariesMicrosoft Message Queue (MSMQ) is the native Windows queue, RabbitMQ is a popular open source queue that supports durable messaging, and nats is an open source in-memory queue that is hugely performant.

The high throughput and low latency of nats messaging make it a good choice to communicate between containers, and there is an official image for nats on Docker Hub. nats is a Go application that runs cross-platform and there...
