How to provide for Docker Volume ?

[seepine]

I'm sorry, I can't find where the problem is, and I can only seek help here.

Nfs Server with docker-compose

In ubuntu24 server 192.168.100.134

services:
  nfs-server:
    image: erichough/nfs-server
    ports:
      - '2049:2049'
      - '2049:2049/udp'
      - '111:111'
      - '111:111/udp'
      - '32765:32765'
      - '32765:32765/udp'
      - '32767:32767'
      - '32767:32767/udp'
    privileged: true
    cap_add:
      - SYS_ADMIN
    environment:
      - NFS_EXPORT_0=/nfs *(rw,insecure,sync,all_squash,no_subtree_check)
    volumes:
      - './data:/nfs'

And the log

$ docker compose up

For docker volume

version: '3.9'
services:
  db:
    image: postgres:16
    restart: unless-stopped
    ports:
      - 5432:5432
    volumes:
      - postgres_data:/var/lib/postgresql/data
    environment:
      POSTGRES_DB: postgres
      POSTGRES_USER: postgres
      POSTGRES_PASSWORD: postgres

volumes:
  postgres_data:
    driver: local
    driver_opts:
      type: "nfs"
      o: "addr=192.168.100.134,nolock,soft,rw"
      device: ":/nfs"

But i got error msg

failed to populate volume: error while mounting volume '/var/lib/docker/volumes/postgres_postgres_data/_data': failed to mount local volume: mount :/:/var/lib/docker/volumes/postgres_postgres_data/_data, data: addr=192.168.100.134: permission denied
