fingerprint property

String? fingerprint
getter/setter pair

Specifies a fingerprint for instance settings, which is essentially a hash of the instance settings resource's contents and used for optimistic locking.

The fingerprint is initially generated by Compute Engine and changes after every request to modify or update the instance settings resource. You must always provide an up-to-date fingerprint hash in order to update or change the resource, otherwise the request will fail with error 412 conditionNotMet. To see the latest fingerprint, make a get() request to retrieve the resource.

Implementation

core.String? fingerprint;
