$ gcloud beta compute instances remove-tags example-instance \
    --tags tag-1,tag-2

POSITIONAL ARGUMENTS

INSTANCE_NAME

Name of the instance to set tags on.

REQUIRED FLAGS

Exactly one of these must be specified:

--all

Remove all tags from the instance.

--tags=TAG,[TAG,...]

Specifies strings to be removed from the instance tags. Multiple tags can be removed by repeating this flag.

OPTIONAL FLAGS

--zone=ZONE

Zone of the instance to set tags on. If not specified, you may be prompted to select a zone. gcloud will attempt to identify the zone by searching for resources in your project. If the zone cannot be determined, you will then be prompted with all Google Cloud Platform zones.
To avoid prompting when this flag is omitted, you 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
