gcloud alpha compute instances add-tags

NAME: gcloud alpha compute instances add-tags - add tags to Compute Engine virtual machine instances
SYNOPSIS: gcloud alpha compute instances add-tags INSTANCE_NAME --tags = TAG , [ TAG , …] [ --zone = ZONE ] [ GCLOUD_WIDE_FLAG … ]
DESCRIPTION: (ALPHA) gcloud alpha compute instances add-tags is used to add tags to Compute Engine virtual machine instances.
Tags can be used to identify the instances when adding network firewall rules. Tags can also be used to get firewall rules that already exist to be applied to the instance. See gcloud compute firewall-rules create (1) for more details.

To list instances with their respective status and tags, run:

gcloud compute instances list --format = "table(name,status,tags.list())"

To list instances tagged with a specific tag, tag1 , run:

gcloud compute instances list --filter = 'tags:tag1'
EXAMPLES: To add tags tag-1 and tag-2 to an instance named test-instance , run:
gcloud alpha compute instances add-tags test-instance --tags = tag-1,tag-2
POSITIONAL ARGUMENTS: INSTANCE_NAME

Name of the instance to set tags 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: --tags = TAG ,[ TAG ,…]

Specifies strings to be attached to the instance for later identifying the instance when adding network firewall rules. Multiple tags can be attached by repeating this flag.
OPTIONAL FLAGS: --zone = ZONE

Zone of the instance to set tags 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.
NOTES: This command is currently in alpha and might change without notice. If this command fails with API permission errors despite specifying the correct project, you might be trying to access an API with an invitation-only early access allowlist. These variants are also available:
