The document discusses setting up an NFS server in an LXC container on Ubuntu 16.04. It explains the steps to create the LXC container, install the NFS server, export a directory, and apply the configuration. It then provides an overview of persistent volumes and persistent volume claims in Kubernetes, describing how they decouple storage and pod lifecycles by connecting persistent volumes to pods through claims.

 Export the desired Directory by adding to /etc/exports
/nfs-share *(rw,async,no_subtree_check,no_root_squash)
 Apply the config
sudo exportfs -a
