In this chapter I introduced Docker, an application platform that can run new and old apps in lightweight units of compute called containers. Companies are moving to Docker for efficiency, security, and portability. I covered:
- How Docker works on Windows and how containers are licensed
- The key Docker concepts: images, registries, containers, and swarms
- The options to run Docker on Windows 10, Windows Server 2016, and Azure
If you're planning to work along with the code samples in the rest of the book, you should have a working Docker environment by now. In Chapter 2, Packaging and Running Applications as Docker Containers, I'll move on to packaging more complex apps as Docker images and showing how to manage state in containers with Docker volumes.
