Peristent Storage
=================
0. Install nfs-common in worker node
sudo apt install -y nfs-common

1. Prepare master to share storage
sudo apt install -y nfs-kernel-server
sudo mkdir /opt/share
sudo chmod 1777 /opt/share
echo 'Hello World' | sudo tee /opt/share/welcome.txt
echo '/opt/share *(rw,sync,no_root_squash,subtree_check)' | sudo tee -a /etc/exports
sudo exportfs -ra
sudo apt install -y nfs-common
showmount -e master
sudo mount master:/opt/share /mnt
ls /mnt
sudo umount /mnt

2. Create the PersistentVolume (PV)
kubectl apply -f 3s-pv.yaml
kubectl get pv

3. Create a PersistentVolumeClaim (PVC) in your project
kubectl create -f 3s-pvc.yaml
kubectl get pvc
kubectl get pv

4. Update the deployment
kubectl apply -f 3s-web.yaml

5. Check the storage
kubectl get svc
curl SERVICE-IP:8080
