SYNOPSIS

glance-cache-cleaner [options]

DESCRIPTION

This is meant to be run as a periodic task from cron.

If something goes wrong while we’re caching an image (for example the fetch times out, or an exception is raised), we create an ‘invalid’ entry. These entries are left around for debugging purposes. However, after some period of time, we want to clean these up.

Also, if an incomplete image hangs around past the image_cache_stall_time period, we automatically sweep it up.

OPTIONS

General options

-h, --help

Show the help message and exit

--version

Print the version number and exit

-v, --verbose

--noverbose

-d, --debug

--use-syslog

--nouse-syslog

Disable the use of syslog for logging

--syslog-log-facility SYSLOG_LOG_FACILITY

syslog facility to receive log lines

--config-dir DIR

Path to a config directory to pull *.conf files from. This file set is sorted, 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 means that configuration from files in a specified config-dir will always take precedence over configuration from files specified by –config-file, regardless to argument order.

--config-file PATH

Path to a config file to use. Multiple config files can be specified by using this flag multiple times, for example, –config-file <file1> –config-file <file2>. Values in latter files take precedence.

--log-config-append PATH --log-config PATH

The name of logging configuration file. It does not disable existing loggers, but just appends specified logging configuration to any other existing logging options. Please see the Python logging module documentation for details on logging configuration files. The log-config name for this option is deprecated.

--log-format FORMAT

A logging.Formatter log message format string which may use any of the available logging.LogRecord attributes. Default: None

--log-date-format DATE_FORMAT

Format string for %(asctime)s in log records. Default: None

--log-file PATH, --logfile PATH

(Optional) Name of log file to output to. If not set, logging will go to stdout.

--log-dir LOG_DIR, --logdir LOG_DIR

(Optional) The directory to keep log files in (will be prepended to –log-file)

FILES

/etc/glance/glance-cache.conf
