Each Dockerfile is a script, composed of various commands (instructions) and arguments listed successively to automatically perform actions on a base image in order to create (or form) a new one. They are used for organizing things and greatly help with deployments by simplifying the process start-to-finish.

Create a Docker image from an existing container: In this case, you start with an existing image, customize it with the changes you want, then build a new image from it. Use a Dockerfile: In this case, you use a file of instructions the Dockerfile to specify the base image and the changes you want to make to it.

A Dockerfile must be created with no extension. To do this in Windows, create the file with your editor of choice, then save it with the notation "Dockerfile" (including the quotes). For additional examples of Dockerfiles for Windows, see the Dockerfile for Windows repository.

A base image is the image that is used to create all of your container images. Your base image can be an official Docker image, such as Centos, or you can modify an official Docker image to suit your needs, or you can create your own base image from scratch.

I'd recommend keeping the Dockerfile with the source as you would a makefile. The build context issue means most Dockerfiles are kept at or near the top-level of the project. You can get around this by using scripts or build tooling to copy Dockerfiles or source folders about, but it gets a bit painful.
