gcloud alpha compute instances update-from-file

NAME
gcloud alpha compute instances update-from-file - update a Compute Engine virtual machine instance using a configuration file
SYNOPSIS
gcloud alpha compute instances update-from-file INSTANCE_NAME [--minimal-action=MINIMAL_ACTION] [--most-disruptive-allowed-action=MOST_DISRUPTIVE_ALLOWED_ACTION] [--source=SOURCE] [--zone=ZONE] [GCLOUD_WIDE_FLAG]
DESCRIPTION
(ALPHA) Update a Compute Engine virtual machine instance using a configuration file.
POSITIONAL ARGUMENTS
INSTANCE_NAME
Name of the instance to update. 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
FLAGS
--minimal-action=MINIMAL_ACTION
If specified, this action or higher level action is performed on the instance irrespective of what action is required for the update to take effect. If not specified, 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 higher action to be applied to the instance. If not specified, the default will be REFRESH
--source=SOURCE
Path to a YAML file containing instance configuration export data. The YAML file must not contain any output-only fields. Alternatively, you may omit this flag to read from standard input. A schema describing the export/import format can be found in: $CLOUDSDKROOT/lib/googlecloudsdk/schemas/compute/alpha/Instance.yaml.
--zone=ZONE
Zone of the instance to update. If not specified, the user may be prompted to select a zone. gcloud will attempt to identify the zone by searching for resources in the user's project. If the zone cannot be determined, the user will then be prompted with all 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: --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.

EXAMPLES
A virtual machine instance can be updated by running:
  $ gcloud alpha compute instances update-from-file my-instance \
      --source=<path-to-file>
