This document provides an overview of a webinar on Docker containers. It introduces Docker terminology like images and containers. It discusses how Docker provides isolation while running on a single shared kernel. It also outlines some benefits of Docker for development teams like continuous integration and parallel testing. Finally, it announces there will be a live demo and Q&A on Docker basics, benefits, and using Docker Compose.
