Part 1 Understanding Docker containers and images

Welcome to Learn Docker in a Month of Lunches. This first part gets you up to speed quickly on the core Docker concepts: containers, images, and registries. You’ll see how to run applications in containers, package your own applications in containers, and share those applications for other people to use. You’ll also learn about storing data in Docker volumes, as well as how you can run stateful apps in containers. By the end of these first chapters, you’ll be comfortable with all the fundamentals of Docker, and you’ll be learning with best practices baked in from the start.
