glance-manage [options]


glance-manage is a utility for managing and configuring a Glance installation. One important use of glance-manage is to setup the database. To do this run:

glance-manage db_sync

Note: glance-manage commands can be run either like this:

glance-manage db sync

or with the db commands concatenated, like this:

glance-manage db_sync


This is the prefix for the commands below when used with a space rather than a _. For example “db version”.
This will print the current migration level of a glance database.
db_upgrade [VERSION]
This will take an existing database and upgrade it to the specified VERSION.
Place the database under migration control.
db_sync [VERSION]
Place an existing database under migration control and upgrade it to the specified VERSION.
Run this command to expand the database as the first step of a rolling upgrade process.
Run this command to migrate the database as the second step of a rolling upgrade process.
Run this command to contract the database as the last step of a rolling upgrade process.
db_export_metadefs [PATH | PREFIX]
Export the metadata definitions into json format. By default the definitions are exported to /etc/glance/metadefs directory. Note: this command will overwrite existing files in the supplied or default path.
db_load_metadefs [PATH]
Load the metadata definitions into glance database. By default the definitions are imported from /etc/glance/metadefs directory.
Unload the metadata definitions. Clears the contents of all the glance db tables including metadef_namespace_resource_types, metadef_tags, metadef_objects, metadef_resource_types, metadef_namespaces and metadef_properties.


General Options

-h, --help
Show the help message and exit
Print the version number and exit
-v, --verbose
Print more verbose output
Disable verbose output
-d, --debug
Print debugging output (set logging level to DEBUG instead of default WARNING level)
Disable debugging output
Use syslog for logging
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)
