우선 PV(Persistent Volume) 생성.

cychong@mini1:~/work/helm-chart$ kubectl delete -f nginx/nginx-pv.yaml
persistentvolume "nginx-pv" deleted
cychong@mini1:~/work/helm-chart$ kubectl create -f nginx/nginx-pv.yaml
persistentvolume/nginx-pv created
cychong@mini1:~/work/helm-chart$ helm install podcast nginx
