fingerprint property

String? fingerprint
getter/setter pair

Specifies a fingerprint for this request, which is essentially a hash of the metadata's contents and used for optimistic locking.

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