laravel - 在Docker容器中运行Laravel应用，但autoload.php文件不存在

Question

我在docker中执行laravel应用时遇到问题，我的容器已成功启动，但是当我尝试访问我的应用时，出现此错误:

Warning: require(/var/www/public/../vendor/autoload.php): failed to open stream: No such file or directory in /var/www/public/index.php on line 24

Fatal error: require(): Failed opening required '/var/www/public/../vendor/autoload.php' (include_path='.:/usr/local/lib/php') in /var/www/public/index.php on line 24

我不知道为什么，因为我在Dockerfile上运行了composer安装，因此我认为存在自动加载文件？

请找到我的 Dockerfile :

FROM php:7.2-fpm

# Copy composer.lock and composer.json
COPY composer.lock composer.json /var/www/

# Set working directory
WORKDIR /var/www

# Install composer

# Add user for laravel application
RUN groupadd -g 1000 www
RUN useradd -u 1000 -ms /bin/bash -g www www

# Copy existing application directory contents
COPY . /var/www

# Run composer install
RUN composer install
RUN composer dump-autoload

# Copy existing application directory permissions
COPY --chown=www:www . /var/www

# Change current user to www
USER www

# Expose port 9000 and start php-fpm server
EXPOSE 9000
CMD ["php-fpm"]

我的 docker-compose.yml :

也许您已经遇到了这个问题？

谢谢

我只是有同样的问题。
由于某些原因，在安装应用程序根卷以镜像本地环境(-./:/var/www)时，无法创建或写入vendor文件夹。
将卷“/ var / www / vendor”添加到您的应用程序。这将在容器中创建文件夹，并防止对该文件夹进行镜像。这使Laravel可以控制该文件夹并在其中创建所需的文件夹。
如果有人解释为什么镜像时无法创建或写入供应商文件夹，将不胜感激!
