Docker Compose、Nginx和MariaDB的最佳实践：高可用PHP应用程序架构设计

# 使用基础PHP镜像
FROM php:7.4-fpm

# 安装PHP依赖项
RUN apt-get update && apt-get install -y 
    git 
    zip 
    curl 
    libpng-dev 
    libonig-dev 
    libxml2-dev 
    && docker-php-ext-install pdo_Mysql mbstring exif pcntl bcmath gd

# 设置工作目录
WORKDIR /var/www/html

# 将应用程序复制到工作目录
COPY . .

# 安装依赖项
RUN curl -sS https://getcomposer.org/installer | php -- --install-dir=/usr/local/bin --filename=composer
RUN composer install --no-scripts --no-autoloader

# 自动生成Autoload文件
RUN composer dump-autoload --optimize

# 修改文件权限
RUN chown -R www-data:www-data /var/www/html/storage

# 启动PHP-FPM服务器
CMD ["php-fpm"]

# 暴露端口
EXPOSE 9000
