optional arguments:
  -h, --help            show this help message and exit
  --config-dir DIR      Path to a config directory to pull *.conf files from.
                        This file set is sorted, so as to provide a
                        predictable parse order if individual options are
                        over-ridden. The set is parsed after the file(s)
                        specified via previous --config-file, arguments hence
                        over-ridden options in the directory take precedence.
  --config-file PATH    Path to a config file to use. Multiple config files
                        can be specified, with values in later files taking
                        precedence. The default files used are: None.
  --debug, -d           Print debugging output (set logging level to DEBUG
                        instead of default WARNING level).
  --external-net EXTERNAL_NET
                        Name or ID of external network, defaults to
                        env[SHAKER_EXTERNAL_NET]. If no value provided then
                        Shaker picks any of available external networks.
  --flavor-name FLAVOR_NAME
                        Name of image flavor. The default is created by
                        shaker-image-builder.
  --image-builder-template IMAGE_BUILDER_TEMPLATE
                        Heat template for the image builder.
  --image-name IMAGE_NAME
                        Name of image to use. The default is created by
                        shaker-image-builder.
  --log-config-append PATH, --log_config PATH
                        The name of a logging configuration file. This file is
                        appended to any existing logging configuration files.
                        For details about logging configuration files, see the
                        Python logging module documentation.
  --log-date-format DATE_FORMAT
                        Format string for %(asctime)s in log records. Default:
                        None .
  --log-dir LOG_DIR, --logdir LOG_DIR
                        (Optional) The base directory used for relative --log-
                        file paths.
  --log-file PATH, --logfile PATH
                        (Optional) Name of log file to output to. If no
                        default is set, logging will go to stdout.
  --log-format FORMAT   DEPRECATED. A logging.Formatter log message format
                        string which may use any of the available
                        logging.LogRecord attributes. This option is
                        deprecated. Please use logging_context_format_string
                        and logging_default_format_string instead.
  --nodebug             The inverse of --debug
  --nouse-syslog        The inverse of --use-syslog
  --nouse-syslog-rfc-format
                        The inverse of --use-syslog-rfc-format
  --noverbose           The inverse of --verbose
  --os-password <auth-password>
                        Authentication password, defaults to env[OS_PASSWORD].

  --os-tenant-name <auth-tenant-name>
                        Authentication tenant name, defaults to
                        env[OS_TENANT_NAME].
  --os-username <auth-username>
                        Authentication username, defaults to env[OS_USERNAME].
  --syslog-log-facility SYSLOG_LOG_FACILITY
                        Syslog facility to receive log lines.
  --use-syslog          Use syslog for logging. Existing syslog format is
                        DEPRECATED during I, and will change in J to honor
                        RFC5424.
  --use-syslog-rfc-format
                        (Optional) Enables or disables syslog rfc5424 format
                        for logging. If enabled, prefixes the MSG part of the
                        syslog message with APP-NAME (RFC5424). The format
                        without the APP-NAME is deprecated in I, and will be
                        removed in J.
  --verbose, -v         Print more verbose output (set logging level to INFO
                        instead of default WARNING level).

  --os-auth-url <auth-url>
                        Authentication URL, defaults to env[OS_AUTH_URL].
