NFS Server Setup
Introduction
NFS-based storage is recommended for providing persistent storage volumes to Kubernetes Clusters and backing up data of sandbox/pilot environments.
Prerequisites
- One Virtual machine running on the same network as the rest of the nodes, and is accessible by them. For recommended configuration of the VM refer to Hardware Requirements. 
- Use this Storage size estimator to decide storage requirements 
Installation
- Download/copy this install script from https://github.com/mosip/k8s-infra/blob/main/nfs/install-nfs-server.sh into the NFS Server VM 
- Edit the script to change the local path for NFS Storage, under the variable - nfsStorage
- Run this (with root privileges): - ./install-nfs-server.sh
- Make sure to edit the firewall rules of this VM to enable incoming traffic to the NFS server port - tcp 2049and disable incoming traffic on all other ports (excluding SSH)
