I am moving my stateful flask application from single node server to EKS. I have decided to go with AWS EFS as my persistent volume option. The application needs few files (configs, trained ML models etc.) to start so my questions is -

1. Can I pre-populate EFS with required files before I apply K8 deployment yaml with PV, PVC?
2. If yes, then how do I place files exactly at the mountPath where my container can access it? This is a concern because I haven't applied the deployment yaml yet.
