# 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](https://docs.openg2p.org/1.2/deployment/infrastructure-setup/k8s-cluster-requirements).
* Use this [Storage size estimator](https://docs.openg2p.org/1.2/deployment/k8s-cluster-requirements#storage-requirements-for-pilot-environments) 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 2049` and disable incoming traffic on all other ports (excluding SSH)
