DESCRIPTION
    (ALPHA) Updates the parameters of a single Managed Lustre instance.

EXAMPLES
    To update the description of an instance my-instance in location
    us-central1-a run:

        $ gcloud alpha lustre instances update my-instance \
            --location=us-central1-a --description="<updated description>"

POSITIONAL ARGUMENTS
     Instance resource - Identifier. The name of the instance. This represents
     a Cloud resource. (NOTE) Some attributes are not given arguments in this
     group but can be set in other ways.

     To set the project attribute:
      ◆ provide the argument instance on the command line with a fully
        specified name;
      ◆ provide the argument --project on the command line;
      ◆ set the property core/project.

     To set the location attribute:
      ◆ provide the argument instance on the command line with a fully
        specified name;
      ◆ provide the argument --location on the command line.

     This must be specified.

       INSTANCE
          ID of the instance or fully qualified identifier for the instance.

          To set the instance attribute:
          ▸ provide the argument instance on the command line.

FLAGS
     --async
        Return immediately, without waiting for the operation in progress to
        complete.

     --capacity-gib=CAPACITY_GIB
        The storage capacity of the instance in gibibytes (GiB). Allowed values
        are from 9000 to 7632000, depending on the perUnitStorageThroughput.
        See Performance tiers and maximum storage capacities
        (https://cloud.google.com/managed-lustre/docs/create-instance#performance-tiers)
        for specific minimums, maximums, and step sizes for each performance
        tier.

     --description=DESCRIPTION
        A user-readable description of the instance.

     --[no-]gke-support-enabled
        Indicates whether you want to enable support for GKE clients. By
        default, GKE clients are not supported. Deprecated. No longer required
        for GKE instance creation. Use --gke-support-enabled to enable and
        --no-gke-support-enabled to disable.

     --location=LOCATION
        For resources [instance, source-backup], provides fallback value for
        resource location attribute. When the resource's full URI path is not
        provided, location will fallback to this flag value.

     --per-unit-storage-throughput=PER_UNIT_STORAGE_THROUGHPUT
        The throughput of the instance in MBps per TiB. Valid values are 125,
        250, 500, 1000. See Performance tiers and maximum storage capacities
        (https://cloud.google.com/managed-lustre/docs/create-instance#performance-tiers)
        for more information.

     --placement-policy=PLACEMENT_POLICY
        The placement policy name for the instance in the format of
        projects/{project}/locations/{location}/resourcePolicies/{resource_policy}

     --request-id=REQUEST_ID
        An optional request ID to identify requests. Specify a unique request
        ID so that if you must retry your request, the server will know to
        ignore the request if it has already been completed. The server will
        guarantee that for at least 60 minutes since the first request.

        For example, consider a situation where you make an initial request and
        the request times out. If you make the request again with the same
        request ID, the server can check if original operation with the same
        request ID was received, and if so, will ignore the second request.
        This prevents clients from accidentally creating duplicate commitments.

        The request ID must be a valid UUID with the exception that zero UUID
        is not supported (00000000-0000-0000-0000-000000000000).

     IP-based access rules for the Managed Lustre instance. These options
     define the root user squash configuration.

        Set instance.accessRulesOptions back to default value.

     --default-squash-gid=DEFAULT_SQUASH_GID
        The user squash GID for the default access rule. This user squash GID
        applies to all root users connecting from clients that are not matched

        squash).

     --default-squash-mode=DEFAULT_SQUASH_MODE

        be one of:

            root users matching the [ip_ranges][AccessRule.ip_ranges] are not
            squashed.

            If set as the
            [default_squash_mode][google.cloud.lustre.v1alpha.AccessRulesOptions.default_squash_mode],
            root squash is disabled for this instance.

            If the default squash mode is NO_SQUASH, do not set the
            [default_squash_uid][google.cloud.lustre.v1alpha.AccessRulesOptions.default_squash_uid]
            or
            [default_squash_gid][google.cloud.lustre.v1alpha.AccessRulesOptions.default_squash_gid],

    API can be found at: https://cloud.google.com/managed-lustre/docs

NOTES
    This command is currently in alpha and might change without notice. If this
    command fails with API permission errors despite specifying the correct
