Overview

Amazon EFS CSI driver makes possible consuming an EFS file system from an EKS pod via a standard Persistent Volume Claim/Persistent Volume mechanism.

The overall process consists in the following steps:

1. Deploy the Amazon EFS CSI driver to an Amazon EKS cluster
2. Provision the EFS file system statically. Only static volume provisioning is supported, which means that the EFS file system must be created outside the EKS cluster before being used.

Explain how a pod gets the same file system share all the time.
