gcloud alpha compute instances add-resource-policies

NAME: gcloud alpha compute instances add-resource-policies - add resource policies to Compute Engine VM instances
SYNOPSIS: gcloud alpha compute instances add-resource-policies INSTANCE_NAME --resource-policies=[RESOURCE_POLICY,…] [--zone=ZONE] [GCLOUD_WIDE_FLAG …]
DESCRIPTION: (ALPHA) gcloud alpha compute instances add-resource-policies adds resource policies to Compute Engine virtual instances. These policies define time windows in which live migrations take place.
EXAMPLES: To add resource policy pol1 to instance inst1, run this:
gcloud alpha compute instances add-resource-policies inst1 --resource-policies=pol1

For information on how to create resource policies, see:
gcloud compute resource-policies create --help
POSITIONAL ARGUMENTS: INSTANCE_NAME

Name of the instance to add resource policies to. 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
REQUIRED FLAGS: --resource-policies=[RESOURCE_POLICY,…]

A list of resource policy names to be added to the instance. The policies must exist in the same region as the instance.
OPTIONAL FLAGS: --zone=ZONE

Zone of the instance to add resource policies to. If not specified, you might be prompted to select a zone (interactive mode only). gcloud attempts to identify the appropriate zone by searching for resources in your currently active project. If the zone cannot be determined, gcloud prompts you for a selection with all available 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: --access-token-file, --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.
NOTES: This command is currently in alpha and might change without notice. If this command fails with API permission errors despite specifying the correct project, you might be trying to access an API with an invitation-only early access allowlist. These variants are also available:
