Faster Already! You only need to build the image once, and use it until the installed dependencies (like Python packages) or OS-level package versions need to be changed. Not every time your code is modified. Just because you're mounting the code directory, does not mean you can't ADD code to the image.

A build is the process of transforming input parameters into a resulting object. Most often, the process is used to transform input parameters or source code into a runnable image.

With Dockerfile written, you can build the image using the following command: $ docker build . We can see the image we just built using the command docker images.
