Creating a hail Dataproc cluster with a custom image

Our environment is moving to a FedRAMP-approved environment (in Google Cloud). We have a custom Ubuntu image (Ubuntu Pro 22.04) generated for us. In trying to test the image with our Hail environment, we noticed that hailctl defaults to a Debian image. We have attempted to override that, but have been unsuccessful.

Currently, we’re trying alternative build methods using:

gcloud dataproc clusters create

If it’s not possible to manually reconfigure hailctl to use our custom image, do you have any recommendations for a fresh build using our image? Any guidance would be greatly appreciated to either specify our image in hailctl or create a custom cluster.

Thank you.
