I'm using docker-compose to setup a minimal nginx + php-fpm application but for some reason there is no php.ini file on the docker container (I know because phpinfo() says Loaded Configuration File: (none)).

Here's my docker-compose.yml file:

web:
  image: nginx
  ports:
    - "8080:80"
  volumes:
    - ./site.conf:/etc/nginx/conf.d/site.conf
  links:
    - php

php:
  image: php:5-fpm
  volumes:
    - .root:/var/www/html:ro
  command: bash -c "apt-get update && apt-get install -y php5-mysql && php-fpm"

site.conf is pretty straightforward as well:

server {
    index index.php;
    server_name local.myspicesage.com;
    error_log  /var/log/nginx/error.log;
    access_log /var/log/nginx/access.log;
    root /var/www/html;

    location ~ \.php$ {
        try_files $uri =404;
        fastcgi_split_path_info ^(.+\.php)(/.+)$;
        fastcgi_pass php:9000;
        fastcgi_index index.php;
        include fastcgi_params;
        fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
        fastcgi_param PATH_INFO $fastcgi_path_info;
    }
}

And finally I have the most basic index.php possible:

<?php
echo phpinfo();

I really don't want to start from scratch if I don't have to. Is there supposed to be a php.ini file included with the php:5-fpm docker image? If not, is there a generic file I could use to start with?

The container also has /usr/local/etc/php/conf.d and will read and parse every configuration file in that directory.

Notice that it will still say Loaded Configuration File => (none), but that it will also say Additional .ini files parsed and there you will see it walking through that directory ... and the various files that the container puts there: docker-php-ext-XXX.ini. (So it's rather misleading for it to say (none) ...)

It's useful to do things like this:

 php -r 'phpinfo();' | grep -i conf

... which in this case will very quickly show you only the lines in PHP's voluminous output that contain (in upper or lower case) the string conf.

You need to add php.ini file:

  1. Run temporary php container

docker run -d --name php-tmp php:5-fpm

  1. Copy php archive

docker cp php-tmp:/usr/src/php.tar.xz .

  1. Extract php.ini-development or php.ini-production file to config dir. Example:

compose_root/php/php.ini-development

  1. Add volume with php.ini in php container

    volumes:

    • .root:/var/www/html:ro
    • ./php/php.ini-development:/usr/local/etc/php/php.ini
