Docker-Compose 不会处理我的 php.ini 文件

Question

I'm trying to use docker-compose to volume my php.ini file so I can make changes on the fly on my local machine to see how it affects the host machine. Unfortunately the only way I've been able to get the php.ini file into the container is directly during creation in the Dockerfile so far.

Attached is an image of the container running fine with the current settings below.

My Dockerfile is below:

FROM ubuntu:14.04

    apt-get install -y software-properties-common && \

#This will allow us to modify files in the container for testing if we need to
RUN apt-get update && \
    apt-get install -y vim

EXPOSE 80

My docker-compose.yml file is below:

    dblive:
        image: mysql:5.5.52
        volumes:
            - ./db_data_live:/var/lib/mysql

        environment:
            PMA_ARBITRARY : 1
        restart: always
        ports:
            - "8081:80"

    web:
        build: ./
        depends_on:
            - dblive
            - dbdev
        volumes:
            - ./web:/var/www
            - ./config/php.ini:/etc/php5/apache2/conf.d/custom.ini
            - ./logs/apache_error.log:/var/log/apache2/error.log
            - ./logs/apache_access.log:/var/log/apache2/access.log
            - ./config/apache_default.conf:/etc/apache2/sites-enabled/000-default.conf
        restart: always
        ports: 
            - "80:80"
            - "443:443"

I tried following the advice here, can't upate php.ini file in Docker container , by creating a custom.ini file and mounting it in that location. I actually did it correctly I think because if you look at my image I attached for phpinfo(), you can see that under additional .ini files parsed my custom.ini is there at the end. I did a test though by setting asp_tags = On instead of Off and I can't. phpinfo() will always show it as off. Refer to my attached image of it showing it off despite loading my config file.

I'm not even sure if its really honoring any of the commands in there at all?

My file structure

Answer 1

I found the answer, put a file called custom.php.ini in the config directory (if you are following my directory structure).

Set the volumes like this in my example...

volumes:
            - ./web:/var/www
            - ./config/custom.php.ini:/etc/php5/apache2/conf.d/custom.php.ini

By default the scan directory for extra php files will look in the conf.d directory. These files will overwrite the settings of the main php.ini. I tested this with the asp_tag option turning it Off and On. It works fine as long as you do the following below.

The trick to making this work is to use docker-compose down instead of docker-compose kill

This removes the containers and their cache files. PHP only loads the configuration file once at bootup and the other files so changing the php.ini or the custom file after requires this docker-compose down to force the change.

Answer 2

If you are using something like wodby ( docker4php or docker4drupal ) or lando or trying to find an answer "why php.ini doesn't work" (like me), these tools are using their own way to pass configuration into php

I am posting this answer here because I wasted 2 hours to find an answer and I came into this question from google. I want to save some time to others.

Mounting of custom.php.ini will not help.
