Nginx設定ファイルのコンテナ名にアクセス

Question

Dockerでは、docker network create usta_networkコマンドで新しいネットワークを作成し、このネットワークをdocker-compose.ymlファイルのサービス宣言で参照しました。

今はコンテナの名前でサービスをpingできますが、Nginx Upstream宣言の中でコンテナの名前を参照するにはどうすればいいですか？コンテナ間でアクセスするには、どの方法が最適ですか？ nginxの

version: '2' 

services: 
    nginx-main: 
     image: nginx:latest 
     ports: 
     - "80:80" 
     volumes: 
     - ./nginx.conf:/etc/nginx/nginx.conf:ro 
     - /var/log/nginx:/var/log/nginx 
     container_name: nginx_main 
networks: 
    default: 
     external: 
     name: usta_network 
./nginx.conf 

ユーザnginxのため

docker.compose。

http { 

    server { 
     listen 80; 
     index index.php index.html index.htm; 
     server_name example.org www.example.org; 

     location/{ 

     proxy_set_header Host    $host; 
     proxy_set_header X-Real-IP   $remote_addr; 
     proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; 
     proxy_pass http://rahmanusta_upstream; 
     } 
    } 

    upstream rahmanusta_upstream { 

     server rahmanusta_wp:6565; 

    } 
}
