This topic describes how you can configure and use failover, redundancy, and backups for Supply Chain Security Tools (SCST) - Store.
By default the API server has one 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
property in the scst-store-values.yaml
file.
By default, the database has one replica, and restarts with some downtime if it fails.
CautionAlthough you can configure
db_replicas
inscst-store-values.yaml
, this is discouraged becausedb_replicas
is still experimental. The default internal database is not for production use. For production deployments, use an external database.
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.
