This document discusses using NFS for persistent storage in Kubernetes clusters. It shows how an NFS server can be deployed either on-premise or with a cloud provider to provide shared storage for Kubernetes pods. The Kubernetes master, etcd, nodes, registry, and storage API all integrate with the NFS server to enable persistent volumes claims and management of storage resources across the cluster.
