 | 
						|
netdisco-db-deploy - Database deployment for Netdisco
 | 
						|
 | 
						|
=head1 USAGE
 | 
						|
 | 
						|
This script upgrades or initialises a Netdisco database schema.
 | 
						|
 | 
						|
Pre-existing requirements are that there be a database table created and a
 | 
						|
user with rights to create tables in that database. Both the table and user
 | 
						|
name must match those configured in your environment YAML file (default
 | 
						|
C<~/environments/deployment.yml>).
 | 
						|
 | 
						|
Simply run this script, which connects to the database and runs without user
 | 
						|
interaction. If there's no Nedisco schema, it is deployed. If there's an
 | 
						|
unversioned schema then versioning is added, and updates applied.  Otherwise
 | 
						|
only necessary updates are applied to an already versioned schema.
 | 
						|
 |
