Helm pod has unbound immediate PersistentVolumeClaims how to solve?

Question

Kubernetes

I can’t deploy pods using helm, I write like this: helm install stable/mysql
I get: pod has unbound immediate PersistentVolumeClaims
Kubernetis professionals are calling for your help, what am I doing wrong?
PersistentVolumeClaims weighs in statusPending

I read about dynamic volumes in Google, do I need to create them too?
