The document outlines an agenda for a Docker workshop. It will cover setting up Docker on VirtualBox, an introduction to Docker components and architecture, and hands-on exercises. Attendees will learn about building, distributing, and running Docker containers, Dockerfile commands, image repositories, and storage drivers. The presenter will also discuss CoreOS and its integration with Docker.
