docker - 使用主机名而不是IP地址将 Varnish 服务器添加到Nginx

Question

尝试使用docker容器名称而不是IP地址将 Varnish 添加到nginx中。

我尝试过直接将其添加为set_real_ip_from site-varnish，但这是行不通的。

尝试添加上游(如下)，并尝试了set_real_ip_from varnish_backend，但没有运气

upstream varnish_backend {
    server site-varnish;
}

任何帮助，将不胜感激。我在当前工作的conf下面添加了引用。

upstream fastcgi_backend {
    server site-fpm;
}
server {
    listen 80;
    listen 443 ssl;
    server_name localhost;
    location = /ping {
        set_real_ip_from      192.168.176.2;
        real_ip_header        X-Forwarded-For;

        access_log            off;
        allow                 127.0.0.1;
        deny                  all;


        fastcgi_param         SCRIPT_FILENAME  $document_root$fastcgi_script_name;
        include               fastcgi_params;
        fastcgi_pass          fastcgi_backend;
    }
}

docker-compose.yml

version: "2"
services:
  site-varnish:
    build:
      context: ./etc/varnish/
    ports:
      - 80
    networks:
      - frontend

  site-web:
    build:
      context: ./etc/nginx/
    volumes_from:
      - site-appdata
    env_file:
      - ./global.env
    restart: always
    networks:
      - backend
      - frontend

  site-fpm:
    build:
      context: ./etc/7.2-fpm/
    ports:
      - 9000
    volumes_from:
      - site-appdata
    env_file:
      - ./global.env
    networks: 
      - backend

  site-appdata:
    image: tianon/true
    volumes:
      - ./html:/var/www/html

networks:
  frontend:
    external:
      name: webproxy
  backend:
    external:
      name: backbone

我已经根据@LinPy的建议将nginx版本更新为> 1.13.1，并且能够直接在conf中使用set_real_ip_from site-varnish。
