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.

Summary


This chapter was all about the Docker swarm mode, the native clustering option built right into Docker. You learned how to create a swarm and how to add and remove swarm nodes anddeploy services on the swarm connected with an overlay network. I showed that you have to create services for high availability and also discussed how to use secrets to store sensitive application data securely in the swarm.

You can deploy your application as a stack on the swarm using a Compose file, which makes it very easy to group and manage your application components. I demonstrated stack deployment on a single node swarm and on a multi-node swarm running in Azure and managed with Docker Cloud.

High availability in the swarm means you can perform application updates and rollbacks without downtime. You can even take nodes out of commission when you need to update Windows or Docker and have your application still running with the same service level on the remaining nodes.

In the next chapter, I'll look...
