POSITIONAL ARGUMENTS

DISK_NAME

Name of the disk to update.

FLAGS

--update-labels=[KEY=VALUE,...]

List of label KEY=VALUE pairs to update. If a label exists its value is modified, otherwise a new label is created.
Keys must start with a lowercase character and contain only hyphens (-), underscores (_), lowercase characters, and numbers. Values must contain only hyphens (-), underscores (_), lowercase characters, and numbers.

--zone=ZONE

Zone of the disk to update. If not specified and the compute/zone property isn't set, you may be prompted to select a zone.
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.

At most one of these may be specified:

--clear-labels

Remove all labels. If --update-labels is also specified then --clear-labels is applied first.
For example, to remove all labels:

$ gcloud compute disks update --clear-labels

To set the labels to exactly "foo" and "baz":

$ gcloud compute disks update --clear-labels \
  --update-labels foo=bar,baz=qux

--remove-labels=[KEY,...]

List of label keys to remove. If a label does not exist it is silently ignored.
