Generic PHP server for little docker webapps; this just adds some core modules.
The only thing you need to do is mount a host directory into /var/www/html!
This works well when combined with jwilder's nginx reverse proxy. Just set the VIRTUAL_HOST environment variable when running the container and let the proxy do the rest.
If also combining it with the letsencrypt companion, then set the LETSENCRYPT_HOST environment variable to be the same as VIRTUAL_HOST to enable turn-key SSL.
