Hi @dwchiang

Is there any chance to support php5? As I know some customers are still running their workload on PHP5.

So happy to see that more and more people find this project is useful :)

There are sort of many dependency between OS, nginx, php and php packages that may break the docker build.

Let me see if I can make some of it running :p

I will try to automate part of this project to reduce the dependency check workload and speed up the version expanding of each main components in this project.
