Release Notes

Upgrade note: REST database consolidation

The NICo REST API database has moved from a standalone PostgreSQL instance to the shared Zalando-managed nico-pg-cluster. A new nico_rest database and nico-rest.nico user are provisioned automatically (gated on rest.enabled: true). Database credentials are now synced by External Secrets Operator as the nico-rest-pg-creds secret in the nico-rest namespace, replacing the former db-creds secret.

To upgrade from v0.x, do the following:

1. Back up the REST database from the old standalone PostgreSQL pod.

2. Run ./setup.sh --skip-rest to provision the prerequisites and External Secrets without starting the REST chart or its migration job.

3. Quiesce all writes to the existing REST API.

4. Restore the backup into nico_rest on nico-pg-cluster.

5. Rerun ./setup.sh without --skip-rest.

   The REST chart and nico-rest-db migration job start only after the restore is complete.
