   * - Flag
     - Description
   * - :code:`--m_host`
     - Hostname or IP address of the Manta Manager. This must be accessible by the Manta Node.
   * - :code:`--m_port`
     - Port on which the Manta Manager is running. The default gRPC port is typically 50051.
   * - :code:`--ls_host`
     - Hostname or IP address of the Light Server. Defaults to `localhost`.
   * - :code:`--ls_port`
     - Port for the Light Server. Defaults to 50052.
   * - :code:`--data_folder`
     - Folder containing the data to be processed by the tasks running in the Docker containers.
   * - :code:`--log_filename`
     - Path to the log file where Manta Node will write its logs.
   * - :code:`--secured_token`
     - Token provided by the Manta Manager in secured mode for the first connection.
   * - :code:`--ca_port`
     - Port for the Certification Authority. Defaults to 50050.
   * - :code:`--alias`
     - Alias name for convenient selections
   * - :code:`--random_id`
     - Make Node ID as a random ID
   * - :code:`--debug`
     - Debug mode - All logs are printed and saved into a file.
   * - :code:`-v`
     - Increases the verbosity of logs. Use :code:`-v`, :code:`-vv`, or :code:`-vvv` to increase the verbosity level.

.. warning::

   The combination :code:`-vvv` with :code:`--debug` allows you to print all logs (:code:`INFO`, :code:`DEBUG`, :code:`ERROR`) and also store these logs in an embedded database (file: :code:`.manta/traces.db`).
   By removing :code:`--debug`, you will only store logs in the embedded database even if they are not printed. If you change :code:`-vvv` to :code:`-v`, only :code:`ERROR` will be saved.
