DESCRIPTION

    On successful start up, you should expect to see:

        [pubsub] This is the Google Pub/Sub fake.
        [pubsub] Implementation may be incomplete or differ from the real system.
        ...

        $ gcloud alpha emulators pubsub 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/pubsub. 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. The default value

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. This variant is also available:

        $ gcloud beta emulators pubsub start
