AK/DK is an Akka.NET extension for interacting with, and responding to, the Docker API.
Docker, itself, is an inherently stateful system; anyone can write code to call the Docker API and start a container, but things get more difficult if you want to start a container, wait for it to finish, and then perform another action. This is where a toolkit like Akka.NET (and AK/DK) can help.
To see what you can do with AK/DK, have a look at the orchestration engine example or the test harness.
Note - this is a work-in-progress; please feel free to open an issue for questions, feedback, or if you'd like to pitch in! :)
