PHP customization

For customization a placeholder /opt/docker/etc/php/php.ini is available which will be loaded as last configuration file. All settings can be overwritten in this ini file.

Either use COPY inside your Dockerfile to overwrite this file or use RUN echo memory_limit = 128 M >> /opt/docker/etc/php/php.ini to set specific php.ini values.

Nginx customization

This image has two directories for configuration files which will be automatic loaded.

For global configuration options the directory /opt/docker/etc/nginx/conf.d can be used. For vhost configuration options the directory ``/opt/docker/etc/nginx/vhost.common.conf``can be used.

Any *.conf files inside these direcories will be included either global or the vhost section.
