This document discusses Docker and how it powers the Eclipse Che IDE platform. It provides an overview of Docker concepts like containers, images, and orchestration. It also demonstrates how to build a sample Spring Boot app as a Docker image and run it as a container. Finally, it outlines the agenda for the CheConf2016 conference, including sessions on deploying Che on OpenShift and building an IoT IDE with Che.
