How to retrieve the compute engine name from snapshot API response? - google-cloud-platform

Question

I need to list all the compute instance snapshots successfully created in a project (only for compute instance types), along with the compute engine names.
I am using this API: https://compute.googleapis.com/compute/v1/projects/my-project/global/snapshots
It lists the snapshot and I get the response like this:
"items": [
{
"id": "36734343434334343",
"creationTimestamp": "2020-09-16T11:38:54.780-07:00",

}
From this information, I need to find out what is the VM which is associated with this snapshot. How can I find out the compute engine for which this snapshot is created? Is there any REST API for finding the compute engine from the snapshot?

Answer 1

There is a little misunderstanding here: You snapshot a disk, not a VM. Indeed, you can detach the disk and attach it to another VM. You can also set the disk in multi-reader and attach it to several VM.
So, your question is wrong. You can list, among all your VM, the disk attache to them. Then check if a snapshot exists for each of these disks.
