NAME
    gcloud beta emulators datastore start - start a local datastore emulator

SYNOPSIS
    gcloud beta emulators datastore start [--data-dir=DATA_DIR]
        [--host-port=HOST_PORT] [--no-store-on-disk]
        [--consistency=CONSISTENCY; default=0.9
          | --use-firestore-in-datastore-mode] [GCLOUD_WIDE_FLAG ...]

DESCRIPTION
    (BETA) This command starts a local datastore emulator.

EXAMPLES
    To start a local datastore emulator, run:

        $ gcloud beta emulators datastore start --data-dir=DATA-DIR

FLAGS
     --data-dir=DATA_DIR
        The directory to be used to store/retrieve data/config for an emulator
        run. The default value is <USER_CONFIG_DIR>/emulators/datastore. The
        value of USER_CONFIG_DIR can be found by running:

            $ gcloud info --format='get(config.paths.global_config_dir)'

     --host-port=HOST_PORT
        The host:port to which the emulator should be bound. Can take the form
        of a single address (hostname, IPv4, or IPv6) and/or port:

            [ADDRESS][:PORT]

        In this format you must enclose IPv6 addresses in square brackets: e.g.

            [2001:db8:0:0:0:ff00:42:8329]:8080

        The default value is localhost:8081.

     --store-on-disk
        Whether data should be persisted to disk. Enabled by default, use
        --no-store-on-disk to disable.

     At most one of these can be specified:

       --consistency=CONSISTENCY; default=0.9
          Fraction of eventually consistent operations that should succeed
          immediately. Setting to 1.0 can be useful for unit tests, but may
          mask incorrect assumptions about non-ancestor queries which are
          eventually consistent.

       --use-firestore-in-datastore-mode
          Runs the emulator in Cloud Firestore in Datastore Mode. Reads are
          always strongly consistent and --consistency flag may not be
          specified.

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 beta and might change without notice. This
    variant is also available:

        $ gcloud alpha emulators datastore start
