Mohammed Zaghloul is a senior front-end developer who has experience with C#, Angular, jQuery, and Ember. He will be giving a workshop on Docker that covers: (1) a quick introduction to Docker, (2) running a HelloWorld Docker container, and (3) building a Docker image and creating a containerized web application. Docker allows developers to package applications and dependencies into standardized units called containers that can be run anywhere. It uses a client-server architecture where the Docker client communicates with the Docker daemon to build, run, and distribute containers. Important concepts include Docker images, which are templates for creating containers, and containers, which are runnable instances of images.
