πŸŽ€ OPTIONS πŸŽ€

General options (the main character lineup)

  • -h, --help β€” shows you the help message and then dips. bye πŸ‘‹
  • --version β€” prints the version number and exits
  • -v, --verbose β€” more verbose output, give me ALL the tea πŸ«–
  • --noverbose β€” nope, turn the verbose output off
  • -d, --debug β€” prints debugging output (sets logging level to DEBUG instead of the default WARNING level) πŸ”₯
  • --nodebug β€” debugging output, but make it off
  • --use-syslog β€” use syslog for logging
  • --nouse-syslog β€” disable using syslog for logging
  • --syslog-log-facility SYSLOG_LOG_FACILITY β€” the syslog facility that receives log lines
  • --config-dir DIR β€” path to a config directory to pull *.conf files from. This file set is sorted, so you get a predictable parse order if individual options get over-ridden. The set is parsed after the file(s) specified via previous --config-file, arguments β€” hence over-ridden options in the directory take precedence. Which basically means: configuration from files in a specified config-dir will always take precedence over configuration from files specified by --config-file, regardless to argument order. periodt πŸ’…
  • --config-file PATH β€” path to a config file to use. You can specify multiple config files by using this flag multiple times, for example, --config-file <file1> --config-file <file2>. Values in latter files take precedence. last one wins, it's giving sibling rivalry 😭
  • --log-config-append PATH, --log-config PATH β€” the name of the logging configuration file. It does not disable existing loggers, it just appends the specified logging configuration to any other existing logging options. Please see the Python logging module documentation for details on logging configuration files. (heads up: the log-config name for this option is deprecated ⚠️)
  • --log-format FORMAT β€” a logging.Formatter log message format string, which may use any of the available logging.LogRecord attributes. Default: None
  • --log-date-format DATE_FORMAT β€” format string for %(asctime)s in log records. Default: None
  • --log-file PATH, --logfile PATH β€” (optional) name of the log file to output to. If it's not set, logging will go to stdout
  • --log-dir LOG_DIR, --logdir LOG_DIR β€” (optional) the directory to keep log files in (it gets prepended to --log-file)

🌸 FILES 🌸

  • /etc/glance/glance-cache.conf β€” the default configuration file for the Glance Cache πŸ—‚οΈ
