NFS Server with Provisioner

NFS server and provisioner for dynamic storage provisioning.

What you will need.

NFS has been tested on CentOS 7 and 8. Provisioner has been tested on OpenShift 3.x and 4.x. You will need to provide the IP address of your NFS host and the network address. Your storageclass name will be: managed-nfs-storage

Deploy NFS

Uses /var/nfsshare as a primary NFS shared location. Uses /var/nfsshare/registry for the registry. Replace your network address and adjust accordingly.

sudo systemctl enable nfs-server rpcbind
sudo systemctl start nfs-server rpcbind
sudo mkdir -p /var/nfsshare/registry
sudo chmod -R 777 /var/nfsshare
sudo chown -R nobody:nobody /var/nfsshare
echo '/var/nfsshare <x.x.x.0>/24(rw,sync,no_root_squash,no_all_squash,no_wdelay)' | sudo tee /etc/exports
sudo setsebool -P nfs_export_all_rw 1
echo '/var/nfsshare <x.x.x.0>/24(rw,sync,no_root_squash,no_all_squash,no_wdelay)' | sudo tee /etc/exports
sudo systemctl restart nfs-server
sudo firewall-cmd --permanent --zone=public --add-service mountd
sudo firewall-cmd --permanent --zone=public --add-service rpc-bind
sudo firewall-cmd --permanent --zone=public --add-service nfs
sudo firewall-cmd --reload
