Docker：Apache2 容器无法与 php7.1 容器通信

Question

我在两个不同的容器中安装了 Apache2 和 PHP-FPM 运行ning。两个容器运行好，但我无法处理 php 文件。当我导航到 php 文件时，浏览器响应 'File not found.' 查看 apache 错误日志，我得到：

[Fri Feb 01 09:50:54.894531 2019] [proxy_fcgi:error] [pid 8:tid 140041300997888] [client 44.82.126.19:65344] AH01071: Got error 'Primary script unknown\n'

原则上，我一直在遵循设置说明 here。搜索其他网站显示类似的设置。

我注意到说明不包括 apache2 PHP 模块，但似乎 fcgi 会处理这个...?

部分调试结果：

我可以访问主机 IP 并呈现一个 HTML 网页。
在 Apache2 容器内，我可以成功 ping PHP容器。所以内部网络正常。
在 PHP 容器中，我可以运行 CLI PHP 命令成功。
我已经检查了PHP-FPM配置文件和"Docker inspect"端口9000的暴露。一切正常。

这看起来像是访问问题。您确定 PHP/FPM 容器可以访问 Apache 指向的目录吗？
