For postgreSQL no need to create PV and PVC?

[djpirra]

I am trying to run your configuration, however, I am trying to figure out where the files are created for the database and cannot find them.

Why we have only a PVC template and not PV and PVCs?

Apologies I am quite new to Kubernetes.

Volume claim templates for statefulsets automatically create PV and PVCs for you based on storage class names and storage configured for the cluster.

kubectl get storageclass will give you the storage available for your cluster, if we use kind in this demo, its standard as the default storage which means the PV will be local node storage

For location of data, you may have to look at earlier episodes where we cover postgres data path locations using configuration

Hope that helps
