Question

Where is php.ini being loaded from in this instance of Docker?

I’m running an instance that comes from this Dockerfile.

Here’s some of my phpinfo:

As we can see Configuration File (php.ini) Path is pointing to /usr/local/etc/php. This value was passed on line 31 of the Dockerfile ENV PHP_INI_DIR /usr/local/etc/php.

But inside my /usr/local/etc/ subfiles I can’t find any php.ini:

As we can see in phpinfo o Loaded Configuration File is empty.

I don’t know where the settings on this page are coming from. Where php.ini is being loaded from?

I also don’t see the php service to try to restart it:

UPDATE: I have php.ini in this folder:

This is the Dockerfile:

See the example of how PHP.ini should be loaded in the library’s own documentation in PHP in Docker:

FROM php:7.2-fpm-alpine

# Use the default production configuration
RUN mv $PHP_INI_DIR/php.ini-production $PHP_INI_DIR/php.ini

# Override with custom opcache settings
COPY config/opcache.ini $PHP_INI_DIR/conf.d/

In this example the author chose to use the production configuration, so he renamed the php.ini-Production file to php.ini. So in your case if there is a file /usr/local/etc/php/php.ini this is where PHP will get the configuration. And the folder /usr/local/etc/php/conf. d/ is for the extension settings, as in the example above is being used a configuration of the option.

If you want to use a configuration of your own, just copy it from your directory to the PHP configuration folder. Example:

COPY config/php.ini $PHP_INI_DIR/php.ini

You can validate php get with the installation cycle from 108 to 151 dockerfile.

Try fetching the . ini in /etc/php/5.6/.... must be there, but inside the box q vc created, then make the attach Id_docker_file p access.

Have q check if sapi was installed, maybe missing pq did not see in the file the wget or apt-get from it, where you could use fpm.

If you have any problem p up app sends in the coments.

Hi Luiz, after your idea I did a search and found php.ini inside the mentioned file. But I’m not understanding how this file is not being considered when we display php.ini settings in the browser. I’ll post my full Dockfile.

I think I understand part of the problem. It seems that the official Dockerfile, is installing php5.6 within /etc/php5/cli/php.ini and then on line 31 he points out ENV PHP_INI_DIR /usr/local/etc/php. He expects this directory to have a php.ini file. I think I should then create a symbolic link in /usr/local/etc/php pointing to /etc/php5/cli/php.ini But I still don’t understand where this php.ini is being loaded from.
