Welcome to Introduction to Docker! In this course you'll learn the foundations of using Docker. You'll learn about images and containers, port mapping, Docker networks, volumes, tagging, and more. By the end of the course you should be comfortable with the basic functionality of Docker.

Containers have existed in some form for a while now. However, it was Docker that brought them into the mainstream. And Docker containers have become synonymous with the word "container" because of their popularity. Docker containers have made it easier for many developers and operations teams to build, ship, and deploy their code.

While Docker containers may only be a transitional technology between virtual machines and unikernels (or something similar), they currently remain one of the more effective ways to ship code. Which is why having an understanding of Docker has become, almost a requirement, for technical engineers.
