Docker 502在浏览器中查看时出现错误的网关

我只是刚刚开始与docker工人，并试图build立一个简单的Magento环境如下所述，但是在完成自述文件中描述的安装步骤之后，我尝试通过导航到http：//在浏览器中查看Magento安装。 0.0.0.0:32781/ ，但只是收到“502坏的网关nginx …”。

在运行docker ps ，我收到以下内容：

 41726c7b6e4b meanbee/magento2-varnish:latest "/bin/sh -c /start.sh" 27 hours ago Up 5 seconds 0.0.0.0:32782->80/tcp dockermagento2_varnish_1 5c543aa89500 meanbee/magento2-nginx:1.9 "/usr/local/bin/do..." 27 hours ago Up 5 seconds 443/tcp, 0.0.0.0:32781->80/tcp dockermagento2_web_1 55ddcc9865c4 meanbee/magento2-php:7.0-cli "/docker-entrypoin..." 27 hours ago Up 4 seconds dockermagento2_cron_1 23b9eccd971c mariadb:10 "docker-entrypoint..." 27 hours ago Up 7 seconds 0.0.0.0:32779->3306/tcp dockermagento2_db_1 

我在这里错过了一步吗？ 我个人发现docker文件有点棘手开始！

Docker日志为5c543aa89500
