options:
  -h, --help            show this help message and exit
  --check-defaults      Report differences between the sample values and current values.
  --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. This option must be set from the command-line.
  --config-file PATH    Path to a config file to use. Multiple config files can be specified, with
                        values in later files taking precedence. Defaults to None. This option
                        must be set from the command-line.
  --exclude-group EXCLUDE_GROUP
                        Groups that should not be validated if they are present in the specified
                        input-file. This may be necessary for dynamically named groups which do
                        not appear in the sample config data.
  --exclude-options EXCLUDE_OPTIONS
                        Exclude options matching these patterns when comparing the current and
                        sample configurations.
  --fatal-warnings      Report failure if any warnings are found.
  --input-file INPUT_FILE
                        Config file to validate.
  --namespace NAMESPACE
                        Option namespace under "oslo.config.opts" in which to query for options.
  --nocheck-defaults    The inverse of --check-defaults
  --nofatal-warnings    The inverse of --fatal-warnings
  --opt-data OPT_DATA   Path to a YAML file containing definitions of options, as output by the
                        config generator.
  --shell_completion SHELL_COMPLETION
                        Display a shell completion script Allowed values: bash, zsh
  --version             show program's version number and exit
