DESCRIPTION
Update a Compute Engine virtual machine instance using a configuration file. Formore information, seehttps://cloud.google.com/compute/docs/instances/update-instance-properties.
EXAMPLES
A virtual machine instance can be updated by running:
gcloudcomputeinstancesupdate-from-filemy-instance--source=<path-to-file>
POSITIONAL ARGUMENTS
INSTANCE_NAME
Name of the instance to update. For details on valid instance names, refer tothe criteria documented under the field 'name' at:https://cloud.google.com/compute/docs/reference/rest/v1/instances
FLAGS
--minimal-action=MINIMAL_ACTION
If specified, this action or higher level action is performed on the instanceirrespective of what action is required for the update to take effect. If notspecified, then Compute Engine acts based on the minimum action required.
--most-disruptive-allowed-action=MOST_DISRUPTIVE_ALLOWED_ACTION
If specified, Compute Engine returns an error if the update requires a higheraction to be applied to the instance. If not specified, the default will beREFRESH.
--source=SOURCE
Path to a YAML file containing configuration export data. Alternatively, you mayomit this flag to read from standard input.For a schema describing theexport/import format, see:$CLOUDSDKROOT/lib/googlecloudsdk/schemas/compute/v1/Instance.yaml.
Note:$CLOUDSDKROOTrepresentstheGoogleCloudCLI'sinstallationdirectory.
--zone=ZONE
Zone of the instance to update. If not specified, you might be prompted toselect a zone (interactive mode only).gcloud attempts to identify theappropriate zone by searching for resources in your currently active project. Ifthe zone cannot be determined,gcloud prompts you for a selection withall available Google Cloud Platform zones.

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

gcloudconfigsetcompute/zoneZONE

A list of zones can be fetched by running:

gcloudcomputezoneslist

To unset the property, run:

gcloudconfigunsetcompute/zone

Alternatively, the zone can be stored in the environment variableCLOUDSDK_COMPUTE_ZONE.
