gcloud compute instances attach-disk

NAME: gcloud compute instances attach-disk - attach a disk to an instance
SYNOPSIS: gcloud compute instances attach-disk INSTANCE_NAME --disk=DISK [--boot] [--csek-key-file=FILE] [--device-name=DEVICE_NAME] [--disk-scope=DISK_SCOPE; default="zonal"] [--force-attach] [--interface=INTERFACE] [--mode=MODE; default="rw"] [--zone=ZONE] [GCLOUD_WIDE_FLAG …]
DESCRIPTION: gcloud compute instances attach-disk is used to attach a disk to an instance. For example,
gcloud compute instances attach-disk example-instance --disk DISK --zone us-central1-a

attaches the disk named 'DISK' to the instance named 'example-instance' in zone us-central1-a.
After you create and attach a new disk to an instance, you must format and mount the disk so that the operating system can use the available storage space. You can attach an existing non-boot disk to more than one instance. For more information, see Share a disk between VMs.
EXAMPLES: To attach a disk named 'my-disk' as a boot disk to an instance named 'my-instance', run:
gcloud compute instances attach-disk my-instance --disk=my-disk --boot

To attach a device named 'my-device' for read-only access to an instance named 'my-instance', run:
gcloud compute instances attach-disk my-instance --device-name=my-device --mode=ro
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: --disk=DISK

The name of the disk to attach to the instance.
OPTIONAL FLAGS: --boot

Attach the disk to the instance as a boot disk.

--csek-key-file=FILE

Path to a Customer-Supplied Encryption Key (CSEK) key file that maps Compute Engine resources to user managed keys to be used when creating, mounting, or taking snapshots of disks.
If you pass - as value of the flag, the CSEK is read from stdin. See https://cloud.google.com/compute/docs/disks/customer-supplied-encryption for more details.

--device-name=DEVICE_NAME

An optional name that indicates the disk name the guest operating system will see. (Note: Device name does not correspond to mounted volume name). Must match the disk name if the disk is going to be mounted to a container with --container-mount-disk (alpha feature).

--disk-scope=DISK_SCOPE; default="zonal"

The scope of the disk. DISK_SCOPE must be one of:

regional

The disk specified in --disk is interpreted as a regional disk in the same region as the instance. Ignored if a full URI is provided to the --disk flag.

zonal

The disk specified in --disk is interpreted as a zonal disk in the same zone as the instance. Ignored if a full URI is provided to the --disk flag.

--force-attach

Attach the disk to the instance even if it is currently attached to another instance. The attachment will succeed even if detaching from the previous instance fails at first. The server will continue trying to detach the disk from the previous instance in the background.

--interface=INTERFACE

The interface of the disk. INTERFACE must be one of:

NVME

NVME

SCSI

SCSI

--mode=MODE; default="rw"

Specifies the mode of the disk. MODE must be one of:

ro

Read-only.

rw

Read-write.

--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.
