Dockerfile is a script that contains instructions for building a Docker image. The author emphasizes the importance of optimizing Dockerfiles, which can save time in the build process and reduce the size of the resulting image. It is highlighted that using the right instructions, such as COPY instead of ADD, is essential to avoid unnecessary complications. The article also presents the use of layers, allowing for more efficient management of bundles while minimizing the amount of data transferred during the image build. Ultimately, the author encourages adherence to the outlined rules to achieve a more efficient and organized approach to working with Docker.
