gcloud beta emulators datastore start

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.
