In addition to this documentation page, you can check the etc/glance.conf.sample sample configuration file distributed with Glance for an example configuration file with detailed comments on what each options does.
Glance has a few command-line options that are common to all Glance programs:
Optional. Default: False
Can be specified on the command line and in configuration files.
Turns on the INFO level in logging and prints more verbose command-line interface printouts.

Turns on the DEBUG level in logging.
Optional. Default: None

Takes a path to a configuration file to use when running the program. If this CLI option is not specified, then we check to see if the first argument is a file. If it is, then we try to use that as the configuration file. If there is no file or there were no arguments, we search for a configuration file in the following order:
- ./glance.conf
- ~/glance.conf
- ~/.glance/glance.conf
- /etc/glance/glance.conf
- /etc/glance.conf
There are a number of configuration options in Glance that control how Glance servers log messages. The configuration options can be specified both on the command line and in the glance.conf config file.
Optional. Default: None
