POSITIONAL ARGUMENTS

INSTANCE_NAME

Name of the instance to update.

FLAGS

--[no-]deletion-protection

Enables deletion protection for the instance. Use --deletion-protection to enable and --no-deletion-protection to disable.

--min-cpu-platform=PLATFORM

When specified, the VM will be scheduled on host with specified CPU architecture or a newer one. To list available CPU platforms in given zone, run:

$ gcloud compute zones describe ZONE \
  --format="value(availableCpuPlatforms)"

Default setting is "AUTOMATIC".
CPU platform selection is available only in selected zones.
You can find more information on-line: cloud.google.com/compute/docs/instances/specify-min-cpu-platform

--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 instance to update. 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.

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 instances update --clear-labels

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

$ gcloud compute instances 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.
