Storage Class with NFS

1 - configure nfs server (10.0.0.200)

apt install nfs-kernel-server

#mkdir --mode=777 /wordpress
#mkdir --mode=777 /mariadb

echo "/wordpress *(rw,sync,no_subtree_check)" >> /etc/exports
echo "/mariadb *(rw,sync,no_subtree_check)" >> /etc/exports
exportfs -a
exportfs -r

systemctl restart nfs-kernel-server

2 - check from manager / nodes
apt update && apt install nfs-common -y
showmount -e ip-address-nfs-server

3. ADD nfs provisioner (on manager / workstation)

# Install helm -
curl https://baltocdn.com/helm/signing.asc | sudo apt-key add -
sudo apt-get install apt-transport-https --yes
echo "deb https://baltocdn.com/helm/stable/debian/ all main" | sudo tee /etc/apt/sources.list.d/helm-stable-debian.list
sudo apt-get update
sudo apt-get install helm

# then
# reference - https://github.com/kubernetes-sigs/nfs-subdir-external-provisioner

helm repo add nfs-subdir-external-provisioner https://kubernetes-sigs.github.io/nfs-subdir-external-provisioner/
helm repo list

# create a ns - storagenfs
kubectl create ns storagenfs

helm install wordpress-storage nfs-subdir-external-provisioner/nfs-subdir-external-provisioner \
--set nfs.server=10.0.0.200 --set nfs.path=/wordpress \
--set storageClass.name=wordpress-data \
--set storageClass.onDelete=true -n storagenfs


helm install mariadb-storage nfs-subdir-external-provisioner/nfs-subdir-external-provisioner \
--set nfs.server=10.0.0.200 --set nfs.path=/mariadb \
--set storageClass.name=mariadb-data \
--set storageClass.onDelete=true -n storagenfs

kubectl get storageclass
helm list -n storagenfs
