$ echo "$(minikube ip) hello.world" | sudo tee -a /etc/hosts
$ POD_NAME=$(kubectl get pod -l service=postgres -o jsonpath="{.items[0].metadata.name}")
$ kubectl exec $POD_NAME --stdin --tty -- createdb -U sample people
$ FLASK_POD_NAME=$(kubectl get pod -l app=flask -o jsonpath="{.items[0].metadata.name}")
$ kubectl exec $FLASK_POD_NAME --stdin --tty -- python manage.py recreate_db
$ kubectl exec $FLASK_POD_NAME --stdin --tty -- python manage.py seed_db
