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.
