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

* Create a file named *Dockerfile* and add the following code to it:



FROM node:11-alpine

ENV diameter=4.0

COPY compute.js .

CMD node compute.js

* Open a command-line. Change the current directory to the directory where you created the *Dockerfile* and the *compute.js* file.

* The following command will build your docker image.

In this lesson, we will go over the step-by-step solution for the exercise: Enable an Image to Be Parameterized.
