By now, you've probably heard the buzz around Docker. It's fundamentally changed the development process and been adopted by software teams of all sizes, and for good reason: Docker makes it considerably easier to create, deploy, and run applications with the use of containers.

Docker is here to stay, and is becoming one of the most in-demand technologies on the market. Mastering it now will help you produce better software, level up your career, and stand out from the crowd. Get started today.

Docker for Developers

Each container is created from an image. You provide the image name to the *docker run* command. Docker first looks for the image locally and uses it when present. When the image is not present locally, it is downloaded from a *registry*.


Throughout this chapter, we have been using images to create containers; but where do images come from? We explore just that in this lesson.
