gcloud compute instances add-labels

NAME
gcloud compute instances add-labels - add labels to Google Compute Engine virtual machine instances
SYNOPSIS
gcloud compute instances add-labels INSTANCE_NAME --labels=[KEY=VALUE,…] [--zone=ZONE] [GCLOUD_WIDE_FLAG]
DESCRIPTION
gcloud compute instances add-labels adds labels to a Google Compute Engine virtual machine instance.
EXAMPLES
To add key-value pairs k0=v0 and k1=v1 to 'example-instance'
gcloud compute instances add-labels example-instance --labels=k0=v0,k1=v1

Labels can be used to identify the instance and to filter them. To find a instance labeled with key-value pair k1, v2

gcloud compute instances list --filter='labels.k1:v2'

To list only the labels when describing a resource, use --format

gcloud compute instances describe example-instance --format='default(labels)'
POSITIONAL ARGUMENTS
INSTANCE_NAME
Name of the instance to operate on. For details on valid instance names, refer to the criteria documented under the field 'name' at: https://cloud.google.com/compute/docs/reference/rest/v1/instances
REQUIRED FLAGS
--labels=[KEY=VALUE,…]
A list of labels to add.
OPTIONAL FLAGS
--zone=ZONE
Zone of the instance to operate on. If not specified, you might be prompted to select a zone (interactive mode only). gcloud attempts to identify the appropriate zone by searching for resources in your currently active project. If the zone cannot be determined, gcloud prompts you for a selection with all available Google Cloud Platform zones.

To avoid prompting when this flag is omitted, the user can set the compute/zone property:

gcloud config set compute/zone ZONE

A list of zones can be fetched by running:

gcloud compute zones list

To unset the property, run:

gcloud config unset compute/zone

Alternatively, the zone can be stored in the environment variable CLOUDSDK_COMPUTE_ZONE.

GCLOUD WIDE FLAGS
These flags are available to all commands: --access-token-file, --account, --billing-project, --configuration, --flags-file, --flatten, --format, --help, --impersonate-service-account, --log-http, --project, --quiet, --trace-token, --user-output-enabled, --verbosity.

Run $ gcloud help for details.
