This document discusses using Swift for server-side development with Docker and Kitura. It provides an agenda that covers a WWDC 2016 Swift session on server-side development, discusses common backend frameworks, and demonstrates setting up a Kitura project in a VirtualBox virtual machine and building and running a Docker container for the project. Code examples are provided for initializing a Swift package, defining routes and starting a Kitura server.
