NFS Server

NFS-based storage is recommended for providing persistent storage volumes to Kubernetes Clusters and backing up data of sandbox/pilot environments.

Installation

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

Install

  • Download/copy this install script from https://github.com/OpenG2P/openg2p-deployment/blob/main/nfs-server/install-nfs-server.sh into the NFS server machine.

  • Run the script 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)

  • For every sandbox/namespace, create a new folder in /srv/nfs folder on the NFS node. Suggested folder structure: /srv/nfs/<cluster name>. Example:

    sudo mkdir /srv/nfs/rancher
    sudo mkdir /srv/nfs/prod
    sudo mkdir /srv/nfs/staging
    sudo chmod -R 777 /srv/nfs

Backups

If your NFS holds critical data, there should be some mechanism to backup the same. On AWS you may use the 'snapshot' feature to schedule periodic (daily/weekly) backups of the VM running NFS.
