Database Management
The default metadata driver for glance uses sqlalchemy, which implies
there exists a backend database which must be managed. The
glance-manage binary provides a set of commands for making
this easier.
The commands should be executed as a subcommand of 'db':
glance-manage db <cmd> <args>
Sync the Database
glance-manage db sync <version> <current_version>
Place a database under migration control and upgrade, creating it first if necessary.
Determining the Database Version
glance-manage db version
This will print the current migration level of a glance database.
Upgrading an Existing Database
glance-manage db upgrade <VERSION>
This will take an existing database and upgrade it to the specified VERSION.
Downgrading an Existing Database
glance-manage db downgrade <VERSION>
This will downgrade an existing database from the current version to the specified VERSION.
