It's been a while since i last built the bluefin image with forge. I now found out that the build process uses some heavy logic. I can always reverse engineer all the --build-args but that is cumbersome and time consuming.
It would be nice if we could just kick of the build process with the included just files and then upload the image to the desired container repository. I would keep the existing mechanism but add an variable / argument which allows for using the just file.
