Dockerfiles are universal scripts, but what if you just want the build artifact and are not interested in the container? This project enables that workflow!
Clone this repository and copy 'docker-script' to your preferred $PATH.
Take any Dockerfile, and add label docker-script.export with path to what you want exported from the image, for example
FROM ubuntu:latest
RUN apt update -y
RUN apt install -y sudo build-essential
WORKDIR /root
ADD main.c .
RUN gcc main.c
LABEL docker-script.export="/root/a.out"Running docker-script in this directory will build the Dockerfile, the app, and automatically extracts the compiled program! Which will be available in $PWD/a.out.
