NAME
gcloud compute instances start - start a stopped virtual machine instance
SYNOPSIS
gcloud compute instances start INSTANCE_NAMES [INSTANCE_NAMES …] [--async] [--csek-key-file=FILE] [--zone=ZONE] [GCLOUD_WIDE_FLAG …]
DESCRIPTION
gcloud compute instances start is used to start a stopped Compute Engine virtual machine. Only a stopped virtual machine can be started.
EXAMPLES
To start a stopped instance named 'example-instance' in zone us-central1-a, run: 
gcloud compute instances start example-instance --zone=us-central1-a
POSITIONAL ARGUMENTS
INSTANCE_NAMES [INSTANCE_NAMES …]
Names of the instances 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
FLAGS
--async
Return immediately, without waiting for the operation in progress to complete.
--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.
--zone=ZONE
Zone of the instances 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.
GCLOUD WIDE FLAGS
