容器看不到其中预建的供应商文件夹

Question

我的项目在重启docker容器后抛出下一个错误：

警告：需要（/var/www/ /var/www/ /vendor/composer/./symfony/polyfill-php80/bootstrap.php): 失败 打开流：中没有这样的文件或目录 '供应商/作曲家/autoload_real.php 第 71 行

在重启容器之前在容器内运行ls vendor/symfony： 之后：

如果删除供应商目录并运行composer install，错误正在解决。

我不是 Docker 的绝地武士。

感谢您的任何帮助/建议！

在您的卷部分，您将主机文件夹 ./project 挂载到容器的 /var/www/project：

    volumes:
      - /var/www/project/vendor/
      - ./project:/var/www/project
      - ./project/.docker/php/local.ini:/usr/local/etc/php/conf.d/local.ini

供应商文件夹通过RUN 命令在您的容器内构建。它可能还在那里。但是，当您运行docker-compose up 时，您指示它在运行它时用主机的./project 文件夹掩盖其中的任何内容。所以容器看不到你之前构建的任何东西。

我的建议是只挂载您需要不时更改的文件夹。例如：

    volumes:
      - /var/www/project/vendor/
      # You're probably uploading files here
      - ./project/public/assets:/var/www/project/public/assets
      # Note: You might need to mount some other files / folders that changes
      - ./project/.docker/php/local.ini:/usr/local/etc/php/conf.d/local.ini

然后容器将正确使用预构建的/vendor，同时存储您需要保留在主机中的东西。
