About Dockerfiles
A Dockerfile is a script of instructions that tells Docker how to build a container image for your application. Each instruction - FROM, COPY, RUN, CMD and others - adds a layer to the image.
This generator produces a straightforward starting point. Real projects often add multi-stage builds, a .dockerignore file, and tuned caching for faster rebuilds.
