SYNOPSIS
gcloud compute instances attach-disk   INSTANCE   [--device-name   DEVICE_NAME]   --disk   DISK   [--format   FORMAT]   [--help]   [--mode   MODE;   default="rw"]   [--project   PROJECT_ID]   [--quiet,   -q]   [--zone   ZONE]   [-h]
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.
POSITIONAL ARGUMENTS
INSTANCE
The name of the instance to attach the disk to.
FLAGS
--device-name DEVICE_NAME
An optional name that indicates the disk name the guest operating system will see.
--disk DISK
The name of the disk to attach to the instance.
--mode MODE; default="rw"
Specifies the mode of the disk. Supported options are ro for read-only and rw for read-write. If omitted, rw is used as a default. It is an error to attach a disk in read-write mode to more than one instance.
--zone ZONE
The zone of the instance to attach a disk to. If not specified, you will be prompted to select a zone.
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 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.
GLOBAL FLAGS
--format FORMAT
Specify a format for printed output. By default, a command-specific human-friendly output format is used. Setting this flag to one of the available options will serialize the result of the command in the chosen format and print it to stdout. Supported formats are: json, text, yaml.
--help
Display detailed help.
--project PROJECT_ID
The Google Cloud Platform project name to use for this invocation. If omitted then the current project is assumed.
--quiet, -q
Disable all interactive prompts when running gcloud commands. If input is required, defaults will be used, or an error will be raised.
-h
Print a summary help and exit.
