Solution

  • Use docker cp <php_container_name>:/usr/local/etc/php/php.ini-development . to copy the ini file from the container to host. Change the settings as you like then mount the edited file into the container. In the compose file add this to your php service:

      volumes:
    - /home/user/my-edited-php.ini:/usr/local/etc/php/conf.d/my-edited-php.ini

    It should appear in the directory inside the containers /usr/local/etc/php/conf.d folder. This is pulled in as additional config. For editing one change the edit should be added as an additional config file. You will then not have to replace every other config option and when updates are made to the containers default ini files they will be carried over.
