REST Resource: regionInstanceTemplates

Resource: InstanceTemplate

Represents an Instance Template resource.

Google Compute Engine has two Instance Template resources:

You can reuse a global instance template in different regions whereas you can use a regional instance template in a specified region only. If you want to reduce cross-region dependency or achieve data residency, use a regional instance template.

To create VMs, managed instance groups, and reservations, you can use either global or regional instance templates.

For more information, read Instance Templates.

The fingerprint is initially generated by Compute Engine and changes after every request to modify or update tags. You must always provide an up-to-date fingerprint hash in order to update or change tags.

To see the latest fingerprint, make get() request to the instance.

A base64-encoded string.
