这个文件是基于上两篇文章的项目内容，最终的Dockerfile基本如此：

# 如需自定义优先级最高且不可覆盖的配置文件，参考https://dockerfile.readthedocs.io/en/latest/content/DockerImages/dockerfiles/php-nginx.html
# /opt/docker/etc/php/php.webdevops.ini 会覆盖为 /usr/local/etc/php/conf.d/98-webdevops.ini
# copy 99-docker.ini /opt/docker/etc/php/php.ini 此时的配置会覆盖为 /usr/local/etc/php/conf.d/99-docker.ini

# 进程数量配置，以1C2G计算，动态模式：启动 24，最小16，最大64，测试环境1/4, 同时，在测试环境开启错误输出

这个Dockerfile的目的是为了生成最终执行的Dockerfile, 其中包含了nginx, php-fpm, log, crontab 等基本组件，同时提供一些php-fpm的配置选项
