options:
  -h, --help            show this help message and exit
  -c, --config-path CONFIG_FILE
                        Specify config file. Can be given multiple times and may specify
                        directories containing *.yaml files. Top-level keys in later files
                        overwrite ones in earlier files.
  --no-secrets-in-config
                        Reject config options that expect an in-line secret as value.

Config generation mode:
  --generate-config     Generate a config file, then exit.
  --generate-missing-configs, --generate-keys
                        Generate any missing additional config files, then exit.
  --generate-missing-and-run
                        Generate any missing additional config files, then run. This is the
                        default behaviour.

Details for --generate-config:
  -H, --server-name SERVER_NAME
                        The server name to generate a config file for.

                        Specify where additional config files such as signing keys and log config
                        should be stored. Defaults to the same directory as the last config file.
