kubernetes persistent-volumes ubuntu YAML

I've searched everywhere and can't find a clear answer. I'm stuck on something that should probably be simple... Quick question that's been bugging me - I'm running a Kubernetes cluster on Ubuntu 20.04 with kubeadm and have recently deployed an application intended to use a persistent volume. However, I'm working with a 'CrashLoopBackOff' behavior for one of my pods. The logs indicate that the application want to find the mounted directory, which I have defined in my deployment YAML. Here's the relevant part of my deployment configuration: ```yaml apiVersion: apps/v1 kind: Deployment metadata: name: my-app spec: replicas: 1 selector: matchLabels: app: my-app template: metadata: labels: app: my-app spec: containers: - name: my-app-container image: my-app-image:latest volumeMounts: - mountPath: /data name: data-volume volumes: - name: data-volume persistentVolumeClaim: claimName: my-pvc ``` The PersistentVolumeClaim (PVC) is set up correctly, and I've verified that it is bound: ```yaml apiVersion: v1 kind: PersistentVolumeClaim metadata: name: my-pvc spec: accessModes: - ReadWriteOnce resources: requests: storage: 1Gi ``` When I check the pod status using `kubectl get pods`, I see the pod in a `CrashLoopBackOff` state. Inspecting the logs with `kubectl logs my-app-xxxxx` shows the output: ``` behavior: /data directory not found ``` I've verified that the PVC is correctly bound to a PersistentVolume and that the storage class is appropriate. I've also checked the permissions, and the volume should allow write access. I even tried redeploying the application and recreating the PVC but the scenario continues. How can I troubleshoot this further? Is there something I'm missing in the configuration that might cause the volume not to mount properly? This is part of a larger CLI tool I'm building. Any help would be greatly appreciated! How would you solve this?
