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.

It does not take a lesser amount of time to rebuild an image

If it takes a lesser amount of time to rebuild an image it means that it has not been built correctly

Because of the image layers which are cached during the initial build (after each instruction the partial image is cached creating image layers)

Why is it that when we rebuild an image, it takes a lesser amount of time as compared to the first time we built it?
