Hello,

I've made a new version of this config file using the official docker images for Moodle that are now available at https://github.com/moodlehq/moodle-php-apache
It simplifies the script because we don't need to install all the additional packages and php extensions.
Take a look at https://gist.github.com/danielneis/5c6140ec8150c6151a54bccd26950278
