gcloud beta compute instances set-disk-auto-delete

NAME: gcloud beta compute instances set-disk-auto-delete - set auto-delete behavior for disks
SYNOPSIS: gcloud beta compute instances set-disk-auto-delete INSTANCE_NAME (--device-name=DEVICE_NAME | --disk=DISK) [--no-auto-delete] [--zone=ZONE] [GCLOUD_WIDE_FLAG …]
DESCRIPTION: (BETA) $gcloud beta compute instances set-disk-auto-delete is used to configure the auto-delete behavior for disks attached to Compute Engine virtual machines. When auto-delete is on, the persistent disk is deleted when the instance it is attached to is deleted.
EXAMPLES: To enable auto-delete for a disk named 'my-disk' on an instance named 'my-instance', run:
gcloud beta compute instances set-disk-auto-delete my-instance --auto-delete --disk=my-disk

To enable auto-delete for a device named 'my-device' on an instance named 'my-instance', run:
gcloud beta compute instances set-disk-auto-delete my-instance --auto-delete --device-name=my-device
POSITIONAL ARGUMENTS: INSTANCE_NAME

Name of the instance to operate on. 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: Exactly one of these must be specified:

--device-name=DEVICE_NAME

Specifies a disk to set auto-delete for by its device name, which is the name that the guest operating system sees. The device name is set at the time that the disk is attached to the instance, and need not be the same as the persistent disk name. If the disk's device name is specified, then its persistent disk name must not be specified using the --disk flag.

--disk=DISK

Specifies a disk to set auto-delete for by its resource name. If you specify a disk to set auto-delete for by persistent disk name, then you must not specify its device name using the --device-name flag.
OPTIONAL FLAGS: --auto-delete

Enables auto-delete for the given disk. Enabled by default, use --no-auto-delete to disable.

--zone=ZONE

Zone of the instance to operate on. 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.
