SchedulerPredicates failed due to PersistentVolumeClaim is not bound - postgresql

Question

I am using helm with kubernetes on google cloud platform.
i get the following error for my postgres deployment:
SchedulerPredicates failed due to PersistentVolumeClaim is not bound
it looks like it cant connect to the persistent storage but i don't understand why because the persistent storage loaded fine.
i have tried deleting the helm release completely, then on google-cloud-console > compute-engine > disks; i have deleted all persistent disk. and finally tried to install from the helm chart, but the postgres deployment still doesnt connect to the PVC.
my database configuration:
{{- $serviceName := "db-service" -}}
{{- $deploymentName := "db-deployment" -}}
{{- $pvcName := "db-disk-claim" -}}
{{- $pvName := "db-disk" -}}

is this config for kubenetes correct? i have read the documentation and it looks like this should work. i'm new to Kubernetes and helm so any advice is appreciated.
EDIT:
i have added a PersistentVolume and linked it to the PersistentVolumeClaim to see if that helps, but it seems that when i do this, the PersistentVolumeClaim status becomes stuck in "pending" (resulting in the same issue as before).

Answer 1

You don't have a bound PV for this claim. What storage you use for this claim. You need to mention it in the PVC file
