How can I modify php.ini using Railway Nixpacks?


I need to increase the upload_max_filesize directive in php.ini to allow images over 2MB to upload to my Laravel site, which is deployed in Railway using Nixpacks.

I've already tried to include some init_set('upload_max_filesize', '100M') in my routes, including this directive in the nginx.conf, and adding the environment variable PHP_INI_UPLOAD_MAX_FILESIZE in Railway. None of these solutions worked.

How can I modify the php.ini while using Nixpacks in Railway?


Solution

  • Although I could not find any solution to do this using Nixpacks, I finally ended up adding a Dockerfile in the root folder of the project to do the deployment with docker. If Railways detects a Dockerfile in the root folder, it automatically executes the deployment using it.

    Here the Dockerfile I used which is working fine with a Laravel app:

    FROM php:8.1-apache
    
    # Arguments defined in docker-compose.yml
    ARG user
    ARG uid
    
    # Install system dependencies
    RUN apt-get update && apt-get install -y \
        git \
        curl \
        libpng-dev \
        libonig-dev \
        libxml2-dev \
        zip \
        unzip
    
    # Clear cache
    RUN apt-get clean && rm -rf /var/lib/apt/lists/*
    
    # Install PHP extensions
    RUN docker-php-ext-install pdo_mysql mbstring exif pcntl bcmath gd
    
    # Get latest Composer
    COPY --from=composer:latest /usr/bin/composer /usr/bin/composer
    
    # Set up node and npm
    
    RUN curl -sL https://deb.nodesource.com/setup_18.x | bash
    RUN apt-get update && apt-get -y install nodejs 
    
    # Set working directory
    WORKDIR /var/www
    
    RUN apt-get update && apt-get install -y \
            libfreetype6-dev \
            libjpeg62-turbo-dev \
            libpng-dev \
        && docker-php-ext-configure gd --with-freetype --with-jpeg \
        && docker-php-ext-install -j$(nproc) gd
    
    WORKDIR /var/www/html
    COPY . .
    
    #Modify php.ini setings
    
    RUN touch /usr/local/etc/php/conf.d/uploads.ini \
        && echo "upload_max_filesize = 10M;" >> /usr/local/etc/php/conf.d/uploads.ini
    
    #Serve the application
    
    RUN composer install
    RUN npm install
    CMD php artisan migrate --force && php artisan storage:link && php artisan serve --host=0.0.0.0 --port=$PORT
