Provision newly created datasource and dashboard


I am new to Grafana and I have few confusion regarding datasource and dashboard provisioning.

I have deployed Grafana on k8s and also provisioned the datasources and dashboards (using persistent volume), and everything is working fine.

But, my question is, what happens when I add a new datasource and a dashboard? Is there a way to provision the newly created datasources and dahboards? Cause, if the grafana restarts, the new items will be erased.
