Path to a script that streams the desired image on standard output.
This option is mainly intended for use with pkgs.dockerTools.streamLayeredImage so that the intermediate image archive does not need to be stored in the Nix store. For larger images this optimization can significantly reduce Nix store churn compared to using the imageFile option, because you don't have to store a new copy of the image archive in the Nix store every time you change the image. Instead, if you stream the image then you only need to build and store the layers that differ from the previous image.
