Failover, redundancy, and backups for Supply Chain Security Tools - Store

This topic describes how you can configure and use failover, redundancy, and backups for Supply Chain Security Tools (SCST) - Store.

API Server

By default the API server has 1 replica. If the pod fails, the single instance restarts by normal Kubernetes behavior, but there is downtime. If you upgrade, some downtime is possible.

You can configure the number of replicas by using the app_replicas text box in the scst-store-values.yaml file.

Database

By default, the database has one replica, and restarts with some downtime if it fails.

Caution Although you can configure db_replicas in scst-store-values.yaml, this is discouraged because db_replicas is still experimental. The default internal database is not for production use. For production deployments, use an external database.

• Use external postgres database
• AWS RDS postgres configuration

For the default PostgreSQL database deployment, with deploy_internal_db set to true, you can use Velero as the backup method. For information about using Velero as the backup method, see Backups.
