  Warning  FailedScheduling  3m28s (x362 over 23m)  default-scheduler  pod has unbound immediate PersistentVolumeClaims (repeated 2 times)

When following instructions to install Drupal:

kubectl create -f kubernetes/local-volumes.yaml
kubectl create -f kubernetes/postgres.yaml
kubectl create -f kubernetes/drupal.yaml

I only changed the size of the Volume to 2Gi instead of 10Gi
