OpenWrt 中 使用 Docker 安装可道云出错。

Nginx 和 PHP 镜像：

root@OpenWrt:~# docker images
REPOSITORY          TAG                 IMAGE ID            CREATED             SIZE
php                 7.2-fpm             2f2db309f0ae        2 weeks ago         365MB
nginx               latest              274c632b9f13        2 weeks ago         125MB

容器代码
docker run --name myphp-fpm -v /opt/nginx/www:/www -d php:7.2-fpm

docker run --name php-nginx-kodbox -p 8880:7880 -d \
    -v /opt/nginx/www:/usr/share/nginx/html:ro \
    -v /opt/nginx/conf.d:/etc/nginx/conf.d:ro \
    --link myphp-fpm:php \
    nginx

容器在 linux 中运行

root@OpenWrt:~# docker ps -a
CONTAINER ID        IMAGE               COMMAND                  CREATED             STATUS              PORTS                            NAMES
1a7816b52f12        nginx               "/docker-entrypoint.…"   52 minutes ago      Up 11 minutes       80/tcp, 0.0.0.0:8880->7880/tcp   php-nginx-kodbox
e42944b8defa        php:7.2-fpm         "docker-php-entrypoi…"   About an hour ago   Up 52 minutes       9000/tcp                         myphp-fpm

确保路径(/opt/nginx/www)下面有安装 php 解压文件
现在问题是访问 php 文件的时候出现 404，然后我加了个静态 html 文件进去后，是可以访问的。
请问我哪儿出错了？
纯新手学习，谢谢了~~~~~~~~~
