gcloud alpha compute project-zonal-metadata add

NAME
gcloud alpha compute project-zonal-metadata add - add or update project zonal metadata
SYNOPSIS
gcloud alpha compute project-zonal-metadata add --metadata=KEY=VALUE,[KEY=VALUE,…] --zone=ZONE [GCLOUD_WIDE_FLAG …]
DESCRIPTION
(ALPHA) gcloud alpha compute project-zonal-metadata add is used to add or update project zonal metadata for your VM instances. Project zonal metadata values propagate to all VMs within the specified zone. Every VM has access to a metadata server that you can use to query the configured project zonal metadata values. To set metadata for individual instances, use gcloud compute instances add-metadata. For information about metadata, see https://cloud.google.com/compute/docs/metadata.

Only the metadata keys that you provide in the command get mutated. All other existing metadata entries remain the same.

EXAMPLES
To set the project zonal metadata with key=value in the zone us-central1-a for the project my-gcp-project, run: 
gcloud alpha compute project-zonal-metadata add --metadata=key=value --zone=us-central1-a --project=my-gcp-project

For more information and examples for setting project zonal metadata, see https://cloud.google.com/compute/docs/metadata/setting-custom-metadata#set-custom-project-zonal-metadata
