**Note**: Don't like the api very much, but at the same time didn't want to touch the existing commands. Needed this so drafting it here for feedback (or in case someone else needs it).

not sure of the use-case here? can you elaborate? you want to be able to create an image from an existing volume and create a volume from an image?

[rinor]

The idea is to create a volume image and later on create different instance disk volumes from that same image that is already uploaded and available. I.e I'm testing/creating 100 instances that need a persistent volume and don't see a reason to locally create/upload the same thing 100 times.

ah ok, GCP has a disk clone feature that might be a better fit for that? https://cloud.google.com/compute/docs/disks/create-disk-from-source

closing this until I find a better/less intrusive format/api
