=head1 netdisco-db-deploy
|
|
|
|
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/development.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.
