- 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.
- 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. It is an error to attach a disk in read-write mode to more than one instance. For details on how to share persistent disks between multiple instances, refer to https://cloud.google.com/compute/docs/disks/add-persistent-disk#use_multi_instances
--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
property:compute/zone
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
