DESCRIPTION

gcloud compute instances attach-disk is used to attach a disk to an instance. For example,

$ compute instances attach-disk my-instance --disk my-disk
  --zone us-central1-a

attaches the disk named “my-disk” to the instance named “my-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.

--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.

--mode MODE

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.

--project PROJECT

Google Cloud Platform project to use for this invocation.

--quiet

Disable all interactive prompts when running gcloud commands. If input is required, defaults will be used, or an error will be raised.

--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”.

-h

Print a summary help and exit.
