在我的php应用程序中，我有几个通过作曲家安装的依赖项。当我在 mac 机器上本机构建此应用程序时，所有 php 依赖项都已正确安装。当应用程序运行时：命名空间，文件和类都可以通过作曲家的自动加载器找到。
但是，我希望在 docker 容器中运行此应用程序，以便我可以将容器推送到 ECS。当我在容器内运行相同的应用程序(在我的 Mac 上本机运行)时。作曲家的自动加载器找不到某个类，而是抛出如下异常：PHP Fatal error: Uncaught Error: Class ... not found in ....
真正奇怪的部分是，正确的命名空间显示在vendor/composer/autoload_psr4.php中(没有丢失)，并且类文件确实存在于 docker 容器中的供应商目录中。
我能找到的唯一解决方案(让作曲家找到类)是删除供应商的目录并重新运行composer installdocker 容器中的所有目录。但我不想这样做。我应该能够在构建后将容器发布并部署到 ECS，而无需再次安装我的作曲家依赖项。我也尝试在入口点运行composer dump-autoloader，但这并没有解决我的问题。
以前有没有人遇到过这样的问题：php、comper 和 docker？

尝试使用以下 Dockerfile(安装 php 和 composer 之后的片段)：
WORKDIR $WORKDIR
COPY composer.* ./
RUN composer install --no-autoloader
COPY . ./
RUN composer dump-autoload
并将 vendor/添加到 .dockerignore 文件。
我认为这是构建具有由作曲家、npm、yarn 和类似包管理器控制的依赖项的 docker 映像的可取方法。
