• docker-compose.yml 配置, 这里单独配置的一个docker-compose.yml，因为这玩意会更新。。。更新了重新下载证书

version: '3.4'

services:
  proxy:
    image: jwilder/nginx-proxy
    container_name: nginx-proxy
    restart: always
    ports:
      - 80:80
      - 443:443
    labels:
      com.github.jrcs.letsencrypt_nginx_proxy_companion.nginx_proxy: "true"

• 其他项目的docker-compose.yml (多子域名配置同一个证书的，用逗号隔开，只要在某一个容器中配置就可以了，记得最后配置网络（因为是在不同的docker-compose.yml，只有在同一个网络中才有用）)
