DESCRIPTION
    (ALPHA) gcloud alpha compute disks update updates a Compute Engine
    persistent disk.

EXAMPLES
    To update labels 'k0' and 'k1' and remove label 'k3' of a disk, run:

        $ gcloud alpha compute disks update example-disk \
          --zone=us-central1-a --update-labels=k0=value1,k1=value2 \
          --remove-labels=k3

        `_k0_` and `_k1_` are added as new labels if not already present.

    Labels can be used to identify the disk. To list disks with the 'k1:value2'
    label, run:

        $ gcloud alpha compute disks list --filter='labels.k1:value2'

    To list only the labels when describing a resource, use --format to filter
    the result:

        $ gcloud alpha compute disks describe example-disk \
          --format="default(labels)"

    To append licenses to the disk, run:

        $ gcloud alpha compute disks update example-disk \
          --zone=us-central1-a \
          --append-licenses=projects/license-project/global/licenses/\
        license-1,projects/license-project/global/licenses/license-2

    To remove licenses from the disk, run:

        $ gcloud alpha compute disks update example-disk \
          --zone=us-central1-a \
          --replace-licenses=projects/license-project/global/licenses/\
        license-1,projects/license-project/global/licenses/license-2

    To replace a license on the disk, run:

        $ gcloud alpha compute disks update example-disk \
          --zone=us-central1-a \
          --replace-license=projects/license-project/global/licenses/\
        old-license,projects/license-project/global/licenses/new-license

POSITIONAL ARGUMENTS
     DISK_NAME
        Name of the disk to update.

FLAGS
     --access-mode=ACCESS_MODE
        Specifies how VMs attached to the disk can access the data on the disk.
        To grant read-only access to multiple VMs attached to the disk, set
        access-mode to READ_ONLY_MANY. To grant read-write access to only one
        VM attached to the disk, use READ_WRITE_SINGLE. READ_WRITE_SINGLE is
        used if omitted. ACCESS_MODE must be one of: READ_ONLY_MANY,
        READ_WRITE_MANY, READ_WRITE_SINGLE.

     --add-guest-os-features=ADD_GUEST_OS_FEATURES
        Specifies guest OS features to add to the disk. Refer to
        https://cloud.google.com/compute/docs/images/create-custom#guest-os-features
        for a list of available options. ADD_GUEST_OS_FEATURES must be (only
        one value is supported): GVNIC.

     --provisioned-iops=PROVISIONED_IOPS
        Provisioned IOPS of disk to update. Only for use with disks of type
        hyperdisk-extreme.

     --provisioned-throughput=PROVISIONED_THROUGHPUT
        Provisioned throughput of disk to update. The throughput unit is MB per
        sec.

     --size=SIZE
        Size of the disks. The value must be a whole number followed by a size
        unit of GB for gigabyte, or TB for terabyte. If no size unit is
        specified, GB is assumed. For details about disk size limits, refer to:
        https://cloud.google.com/compute/docs/disks

     --update-labels=[KEY=VALUE,...]
        List of label KEY=VALUE pairs to update. If a label exists, its value
        is modified. Otherwise, a new label is created.

        Keys must start with a lowercase character and contain only hyphens
        (-), underscores (_), lowercase characters, and numbers. Values must
        contain only hyphens (-), underscores (_), lowercase characters, and
        numbers.

     --append-licenses=[LICENSE,LICENSE...,...]
        "A list of license URIs or license codes. These licenses will be
        appended to the existing licenses on the disk. Provided licenses can be
        either license URIs or license codes but not a mix of both.

     --remove-licenses=[LICENSE,LICENSE...,...]
        A list of license URIs or license codes. If present in the set of
        existing licenses, these licenses will be removed. If not present, this
        is a no-op. Provided licenses can be either license URIs or license
        codes but not a mix of both.

     --replace-license=OLD_LICENSE,NEW_LICENSE,...,[...]
        A list of license URIs or license codes. The first license is the
        license to be replaced and the second license is the replacement
        license. Provided licenses can be either license URIs or license codes
        but not a mix of both.

     At most one of these can be specified:

       --clear-architecture
          Removes the architecture or processor type annotation from the disk.

       --update-architecture=UPDATE_ARCHITECTURE
          Updates the architecture or processor type that this disk can
          support. For available processor types on Compute Engine, see
          https://cloud.google.com/compute/docs/cpu-platforms.
          UPDATE_ARCHITECTURE must be one of: ARM64, X86_64.

     At most one of these can be specified:

       --clear-labels
          Remove all labels. If --update-labels is also specified then
          --clear-labels is applied first.

          For example, to remove all labels:

              $ gcloud alpha compute disks update --clear-labels

          To remove all existing labels and create two new labels, foo and baz:

              $ gcloud alpha compute disks update --clear-labels \
                --update-labels foo=bar,baz=qux

       --remove-labels=[KEY,...]
          List of label keys to remove. If a label does not exist it is
          silently ignored. If --update-labels is also specified then
          --update-labels is applied first.

     At most one of these can be specified:

       --clear-user-licenses
          Remove all existing user licenses on a disk.

       --update-user-licenses=[LICENSE,...]
          List of user licenses to be updated on a disk. These user licenses
          will replace all existing user licenses. If this flag is not
          provided, all existing user licenses will remain unchanged.

     At most one of these can be specified:

       --region=REGION
          Region of the disk to update. If not specified, you might be prompted
          to select a region (interactive mode only).

          To avoid prompting when this flag is omitted, you can set the
          compute/region property:

              $ gcloud config set compute/region REGION

          A list of regions can be fetched by running:

              $ gcloud compute regions list

          To unset the property, run:

              $ gcloud config unset compute/region

          Alternatively, the region can be stored in the environment variable
          CLOUDSDK_COMPUTE_REGION.

       --zone=ZONE
          Zone of the disk to update. 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.

NOTES
    This command is currently in alpha and might change without notice. If this
    command fails with API permission errors despite specifying the correct
    project, you might be trying to access an API with an invitation-only early
    access allowlist. These variants are also available:

        $ gcloud compute disks update

        $ gcloud beta compute disks update
