create running elastic search pod in GKE auto pilot using already available files.

I have an application running on GKE. I wanted to create the same infrastructure in GKE Auto pilot. Therefore I created elastic search pod using the already running elastic search yaml file. I created statefulset, pvc, discovery. Now, pod is not able to run properly as it is showing issue about PVC unbound and 0/2 pods are unavailable. Maybe I am exactly not sure what's the issue about.

I am looking for someone who fix my pod and make it running and who has experience working with GKE Auto pilot, PVC, PV, GCP etc.
