DESCRIPTION
    (ALPHA) Update a Cloud Spanner instance configuration.

EXAMPLES
    To update display name of a custom Cloud Spanner instance configuration
    'custom-instance-config', run:

        $ gcloud alpha spanner instance-configs update \
            custom-instance-config --display-name=nam3-RO-us-central1

    To modify the instance config 'custom-instance-config' by adding label
    'k0', with value 'value1' and label 'k1' with value 'value2' and removing
    labels with key 'k3', run:

        $ gcloud alpha spanner instance-configs update \
             custom-instance-config --update-labels=k0=value1,k1=value2 \
             --remove-labels=k3

    To clear all labels of a custom Cloud Spanner instance configuration
    'custom-instance-config', run:

        $ gcloud alpha spanner instance-configs update \
            custom-instance-config --clear-labels

    To remove an existing label of a custom Cloud Spanner instance
    configuration 'custom-instance-config', run:

        $ gcloud alpha spanner instance-configs update \
            custom-instance-config --remove-labels=KEY1,KEY2

POSITIONAL ARGUMENTS
     INSTANCE_CONFIG
        Cloud Spanner instance config. The 'custom-' prefix is required to
        avoid name conflicts with Google-managed configurations.

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

     --display-name=DISPLAY_NAME
        The name of this instance configuration as it appears in UIs.

     --etag=ETAG
        Used for optimistic concurrency control.

     --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.

     --validate-only
        Use this flag to validate that the request will succeed before
        executing it.

     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 spanner instance-configs update --clear-labels

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

              $ gcloud alpha spanner instance-configs 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.

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 spanner instance-configs update

        $ gcloud beta spanner instance-configs update
