Storing the Dockerfile in source control is a vital practice for tracking changes made to a Docker image. The Dockerfile acts as the blueprint for the image, detailing all the instructions needed to build it, such as which base image to use, additional packages to install, environment variables to set, and commands to run. By keeping the Dockerfile in a version-controlled repository, developers can effectively manage alterations over time. This allows for clear visibility of when and why changes were made, enabling collaboration and the ability to roll back to previous versions if necessary.

This approach aligns with common software development practices where source code is versioned, ensuring consistency and accountability in the development process, particularly for teams working on collaborative projects.
