服务的不受支持的配置选项。*：'volumes_from'

Question

来自本指南：https://olex.biz/2019/09/hosting-with-docker-nginx-reverse-proxy-letsencrypt/

我有以下文件：

docker-compose.yml

version: '2'

services:
  nginx-proxy:
    image: jwilder/nginx-proxy
    container_name: nginx-proxy
    ports:
      - "80:80"
      - "443:443"
    volumes:
      - conf:/etc/nginx/conf.d
      - vhost:/etc/nginx/vhost.d
      - dhparam:/etc/nginx/dhparam
      - certs:/etc/nginx/certs:ro
      - /var/run/docker.sock:/tmp/docker.sock:ro
    networks:
      - proxy
    restart: always

  letsencrypt:
    image: jrcs/letsencrypt-nginx-proxy-companion
    container_name: nginx-proxy-le
    volumes_from:
      - nginx-proxy
    volumes:
      - certs:/etc/nginx/certs:rw
      - /var/run/docker.sock:/var/run/docker.sock:ro
    restart: always

volumes:
  conf:
  vhost:
  dhparam:
  certs:

networks:
  proxy:
    external:
      name: nginx-proxy

如果我将文件version: '2'的最顶部更改为：version: '3'，则出现以下错误：

ERROR: The Compose file './docker-compose.yml' is invalid because:
Unsupported config option for services.letsencrypt: 'volumes_from'

您能否让我知道要进行以下操作才能进行的必要转换：version: '3'？

谢谢！
