How to configure PV and PVC in AWS-EKS cluster?

Since I bound chat db pv and pvc with gp2 storageclass, it still doesn't work :(

Problem

Since I run pvc without storageClassName, AWS-EKS automatically set my pvc with gp2 storageClassName which is AWS-EBS basic name.

Typically, when using a storage type like NFS, you define the PV directly, reference it to the PVC, and do not use a StorageClass.

StorageClass is primarily used to dynamically provision block storage provided by cloud providers (e.g. AWS, GCP, Azure). Network file systems such as NFS typically do not support dynamic provisioning and require PVs to be set up and managed in advance.

Solved

• Setting the NFS PV's storageClassName to an empty string ("") indicates that the StorageClass is not used.

apiVersion: v1
kind: PersistentVolumeClaim
metadata:
  name: pgadmin-pvc
spec:
  accessModes:
    - ReadWriteMany
  resources:
    requests:
      storage: 100Mi
  storageClassName: ""    # Set empty string like this

• Set private VPC network subnet in /etc/exports
  • /nfs_shared 172.31.1.0/16(rw,sync,no_root_squash,no_subtree_check)
