Jupyterlab installation

kubectl apply -f jupyterlab-pvc.yaml
kubectl apply -f jupyterlab-deployment.yaml
kubectl apply -f jupyterlab-service.yaml

# change permission of home folder in pvc 
# since newly created pvc don't give permission 
# to jupyter user (jovian) to create notebook files
chmod 777 /home/jovyan

# you must perform above step with `sleep infinity` in command
# or can have init-container that does that for you
