Here’s an example of our docker-file for Wiki.JS with NFS DB storage, Postgres and Traefik;

version: "3"
volumes:
  db-data:
      driver_opts:
        type: "nfs"
        o: addr=nfshost.example.com,nolock,soft,rw
        device: ":/mnt/Pool0/WikiJS"
services:
  db:
    image: postgres:11-alpine
    environment:
      POSTGRES_DB: wiki
      POSTGRES_PASSWORD: Supersecurepassword
      POSTGRES_USER: wikijs
    command: postgres -c listen_addresses='*'
    logging:
      driver: "none"
    restart: unless-stopped
    networks:
      - internal
    labels:
     - traefik.enable=false
    volumes:
      - type: volume
        source: db-data
        target: /var/lib/postgresql/data
        volume:
            nocopy: true


  wiki:
    image: ghcr.io/requarks/wiki:2
    depends_on:
      - db
    environment:
      DB_TYPE: postgres
      DB_HOST: db
      DB_PORT: 5432
      DB_USER: wikijs
      DB_PASS: Supersecurepassword
      DB_NAME: wiki
    restart: unless-stopped
    networks:
      - proxy
      - internal
    labels:
      - "traefik.enable=true"
      - "traefik.docker.network=proxy"
      - "traefik.http.routers.ex-wikijs.entrypoints=https"
      - "traefik.http.routers.ex-wikijs.rule=Host(`wikijs.example.com`)"
      - "traefik.http.services.ex-wikijs.loadbalancer.server.port=3000"

networks:
  proxy:
    external: true
  internal:
    external: false

This stands up a postgres instance using the NFS mount as storage, allows the internal network to connect to it, stands up a wiki.js instance and gets it all going for you. All behind a Traefik proxy.
