Docker-magic

This docker image is a POC to provide a php image WITHOUT sources

Proof

$ docker run jderusse/magic php /srv/index.php
Hello World

$ docker run jderusse/magic cat /srv/index.php

$ docker run jderusse/magic ls -al /srv/index.php
-rw-r--r--    1 root     root             1 May 25 21:57 /srv/index.php

1 is the size of the file in bytes.

The original source code is available here : https://gist.githubusercontent.com/jderusse/81050a514f2136efabab5ebd520bc598

How does it work ?

The original source code is downloaded then compiled by the php engine with a simple php -l. The compiled result is stored in the opcache files.

Thanks to the directive validate_timestamps=0 the original files are not used anymore. You can empty thoses file, the application still works because the engine will always use the opcached files.
