Having trouble deploying database to kubernetes cluster - postgresql

Question

I am able to deploy the database service itself, but when I try to deploy with a persistent volume claim as well, the deployment silently fails. Below is the deployment.yaml file I am using. The service deploys fine if I remove the first 14 lines that define the persistent volume claim.
apiVersion: apps/v1
kind: PersistentVolumeClaim
apiVersion: v1
metadata:
name: timescale-pvc-1
namespace: my-namespace
spec:
accessModes:
- ReadWriteOnce
resources:
requests:
storage: 100Gi
storageClassName: standard

Answer 1

Consider StatefulSet for running stateful apps like databases. Deployment is preferred for stateless services.
You are using the below storage class in the PVC.
storageClassName: standard
Ensure the storage class supports dynamic storage provisioning.

Answer 2

Are you creating a PV along with PVC and Deployment? A Deployment, Stateful set or a Pod can only use PVC if there is a PV available.
If you're creating the PV as well then there's a possibility of a different issue. Please share the logs of your Deployment and PVC
