From where is my php.ini being loaded in php Docker container?

Question

I am running this Docker instance of a linux debian:jessie with php 5.6.

This is part of my phpinfo :

As we can see the php.ini should be located at

/usr/local/etc/php

And this is what I have inside /usr/local/etc/

But there is no php.ini inside it.

I the other hand, I have the php.ini inside

So, from where exactly is my php.ini being loaded?

We dont even have a php process running but the php seems to be ok - being displayed phpinfo in the screen.

A little late to the party but since question is still relevant today, let me add a short answer:

Official php:7 images get their settings from /usr/local/etc/php folder.

# First log into the running container
$ docker exec -it «container_name» /bin/bash

# List folder content
$ ls /usr/local/etc/php

# Which outputs following line
conf.d  php.ini-development  php.ini-production

If needed, modifying settings via conf.d folder seems better alternative, since xdebug uses it. For example, you can change upload size by adding uploads.ini to conf.d folder with the following content:

file_uploads = On
memory_limit = 64M
upload_max_filesize = 64M
post_max_size = 64M
max_execution_time = 600
