I have created a custom dataproc image using this command ...
$ python generate_custom_image.py --image-name my-ubuntu18-custom --dataproc-version 1.5-ubuntu18 --customization-script my-customization-script.sh --zone us-central-1 --gcs-bucket gs://dataproc-xxxxxx-imgs
After creation, I tried to list all the custom dataproc images created by me and was surprised to see 83 images. Mine was showing up alongside 82 other images. I expected to see only mine. How to ensure mine is not in the public list of dataproc images?
