As an example, I’ll use WordPress.

Why does my pvc deletes data on the directory I’ve mounted it on Kubernetes?

        volumeMounts:
        - name: wordpress-ws-store
          mountPath: /wordpress
      volumes:
        - name: wordpress-ws-store
          persistentVolumeClaim:
            claimName: wordpress-ws-pvc

and on docker compose it doesn’t?

    volumes:
    - wordpress:/var/www/html

I tried searching around about retainingPolicy but when I read it, it feels like it’s intended use is for not deleting your PVs after deletion. Haven’t tried it yet though.

P.S: Still new to devops.
