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.
|
|
|
|
|
|
Initializing an Empty Database
|
|
------------------------------
|
|
|
|
glance-manage db_sync
|
|
|
|
This will take an empty database and create the necessary tables.
|
|
|
|
|
|
Determining the Database Version
|
|
--------------------------------
|
|
|
|
glance-manage db_version
|
|
|
|
This will print the version of a glance database.
|
|
|
|
|
|
Upgrading an Existing Database
|
|
------------------------------
|
|
|
|
glance-manage db_sync <VERSION>
|
|
|
|
This will take an existing database and upgrade it to the specified VERSION.
|
|
|
|
|
|
Downgrading an Existing Database
|
|
--------------------------------
|
|
|
|
glance-manage downgrade <VERSION>
|
|
|
|
This will downgrade an existing database from the current version to the
|
|
specified VERSION.
