- gcloud alpha compute instances attach-disk - attach a disk to an instance
gcloud alpha 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] [--mode=MODE; default="rw"] [--zone=ZONE] [GCLOUD_WIDE_FLAG ...]
(ALPHA) gcloud alpha compute instances attach-disk is used to
$ 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 (cloud.google.com/compute/docs/disks/add-persistent-disk#formatting the disk so that the operating system can use the available storage space.
Name of the instance to operate on.
The name of the disk to attach to the instance.
Attach the disk to the instance as a boot disk.
Path to a Customer-Supplied Encryption Key (CSEK) key file, mapping Google
Compute Engine resources to user managed keys to be used when creating,
mounting, or snapshotting disks.
If you pass - as value of the flag the CSEK will be read from stdin. See cloud.google.com/compute/docs/disks/customer-supplied-encryption for more details.
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:
- 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.
- 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.
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.
- --mode=MODE; default="rw"
Specifies the mode of the disk. MODE must be one of:
- Read-write. It is an error to attach a disk in read-write mode to more than one instance.
Zone of the instance to operate on. If not specified, you may be prompted to
select a zone. gcloud will attempt to identify the zone by searching for
resources in your project. If the zone cannot be determined, you will then be
prompted with all Google Cloud Platform zones.
To avoid prompting when this flag is omitted, you 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, --configuration, --flags-file, --flatten, --format, --help, --log-http, --project, --quiet, --trace-token, --user-output-enabled, --verbosity. Run $ gcloud help for details.
This command is currently in ALPHA and may change without notice. If this command fails with API permission errors despite specifying the right project, you will have to apply for early access and have your projects registered on the API whitelist to use it. To do so, contact Support at cloud.google.com/support These variants are also available:
