How to use F5 image generator tool to prep BIG-IP images for AWS and Azure

I have a GCP image builder quick snippet in my v1 cloud template BIG-IP article last year (need to update to use v2 templates). The last section shows how to use image builder (at a super high level) but to Chris' point...it is similar.

Note: look in section "Option #4: Edit Latest Template to Use Custom Uploaded Image"
