Access to the Dockerfile from which the image was built.

I’m using this docker image right now: nvcr.io/nvidia/tensorflow:19.10-py3. This is great with things like tftrt enabled out of the box.

However, there are a lot of thing I do not need inside the container, I’d like to build a bare-minimum image with just Tensorflow/TensorRT. Just wondering if I can find the Dockerfile from which the image was built? That would be a excellent starting point.
