    NAME
    gcloud beta compute os-config os-upgrade - upgrade the instances OS version
    SYNOPSIS
    gcloud beta compute os-config os-upgrade INSTANCE_NAME --source-os = SOURCE_OS --target-os = TARGET_OS [ --async ] [ --auto-rollback ] [ --no-create-machine-backup ] [ --log-location = LOG_LOCATION ] [ --timeout = TIMEOUT ; default="2h"] [ --zone = ZONE ] [ GCLOUD_WIDE_FLAG … ]
    DESCRIPTION
    (BETA) gcloud beta compute os-config os-upgrade upgrades the instance's OS version.

    OS Upgrade involves:

    • Create a snapshot and/or machine image for the instance.
    • Create an install media disk and attach it to the instance.
    • Upgrade the OS version.
    • Cleanup install media disk after upgrade.

    Virtual instances, snapshots, machine images, and disks in Compute Engine and files stored on Cloud Storage incur charges. See https://cloud.google.com/compute/docs/images/importing-virtual-disks#resource_cleanup .

    EXAMPLES
    To upgrade a instance named my-instance from windows-2008r2 to windows-2012r2, run: 
     gcloud  
beta  
compute  
os-config  
os-upgrade  
my-instance  
 --source-os 
 = 
windows-2008r2  
 --target-os 
 = 
windows-2012r2
    POSITIONAL ARGUMENTS
    INSTANCE_NAME
    Name of the instance to os-upgrade. 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
    --source-os = SOURCE_OS
    OS version of the source instance to upgrade. SOURCE_OS must be (only one value is supported): windows-2008r2 .
    --target-os = TARGET_OS
    Version of the OS after upgrade. TARGET_OS must be (only one value is supported): windows-2012r2 .
    OPTIONAL FLAGS
    --async
    Return immediately, without waiting for the operation in progress to complete.
    --auto-rollback
    When auto rollback is enabled, the instance and its resources are restored to their original state. Otherwise, the instance and any temporary resources are left in the intermediate state of the time of failure. This is useful for debugging.
    --create-machine-backup
    When enabled, a machine image is created that backs up the original state of your instance. Enabled by default, use --no-create-machine-backup to disable.
    --log-location = LOG_LOCATION
    Directory in Cloud Storage to hold build logs. If not set, gs://<project num>.cloudbuild-logs.googleusercontent.com/ is created and used.
    --timeout = TIMEOUT ; default="2h"
    Maximum time an upgrade can last before it fails as "TIMEOUT". For example, if you specify 2h , the process fails after 2 hours. See $ gcloud topic datetimes for information about duration formats.

    This timeout option has a maximum value of 24 hours.

    --zone = ZONE
    Zone of the instance to os-upgrade. If not specified and the compute/zone property isn't set, you might be prompted to select a zone (interactive mode only).

    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: --access-token-file , --account , --billing-project , --configuration , --flags-file , --flatten , --format , --help , --impersonate-service-account , --log-http , --project , --quiet , --trace-token , --user-output-enabled , --verbosity .

    Run $ gcloud help for details.
