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

When I run the *docker build* command to create an image from a *Dockerfile* file, the resultant image is stored locally on the computer where the *docker build* command is run.

This allows me to run as many containers as I want from the locally created image, but the chances are that I want other computers to be able to run containers from the image I created. We'll learn how to do that in the next chapter.

I can see the images available locally on my computer by running the following command:



In this lesson, we are going to briefly discuss the advantages of having locally stored images.
