3、Docker-compose 配置域名和免费证书（nginx

• 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"
    volumes:
      - ./certs:/etc/nginx/certs:ro
      - ./config/nginx/conf.d:/etc/nginx/conf.d
      - ./acme:/acmecerts
      - ./vhost.d:/etc/nginx/vhost.d
      - ./html:/usr/share/nginx/html
      - /var/run/docker.sock:/tmp/docker.sock:ro
    restart: always
  letsencrypt-companion:
    image: jrcs/letsencrypt-nginx-proxy-companion
    # environment:
    # - ACME_CA_URI=https://acme-staging-v02.api.letsencrypt.org/directory
        #https://acme-staging-v02.api.letsencrypt.org/directory
    container_name: letsencrypt
    restart: always
    volumes:
      - ./certs:/etc/nginx/certs
      - ./vhost.d:/etc/nginx/vhost.d
      - ./html:/usr/share/nginx/html
      - /var/run/docker.sock:/var/run/docker.sock:ro
    depends_on:
      - proxy
    restart: always

networks:
  default:
    external:
      name: nginx_proxy

• 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）)
