上下文： 我已经为在 AWS 上运行的 React 应用程序设置了基本代码。我添加了身份验证和 Graphql 工具。基本上，我完成了本教程中指定的所有内容：https ://aws.amazon.com/getting-started/hands-on/build-react-app-amplify-graphql/ 。

我想 Dockerize 我的应用程序并根据本教程添加了 Dockerfile、Dockerfile.dev 和 docker-compose.yml 文件：https ://medium.com/better-programming/heres-how-you-can-use-docker -with-create-react-app-3ee3a972b04e。我将把我的 Dockerfiles 的内容放在这篇文章的底部。

问题： 我在包含我的 React 应用程序的目录中并运行了docker-compose up命令，但我收到了很多警告，我将把它们放在本段下方。正如我在 docker-compose.yml 中指定的那样，我的应用程序在端口 3000 上成功运行。我的问题是我是否错过了 Dockerfiles 中导致 Docker 抛出所有这些警告的关键代码。我已经将 Docker 用于我在实习期间成功构建的 React 应用程序，但我不确定如果我在 AWS 上运行我的 React 应用程序是否需要添加任何额外的东西。如果有人有任何建议，将不胜感激。如果我在帖子中遗漏了关键信息，请告诉我，并原谅我，因为我对使用 Docker 还是很陌生。

这些警告与添加到 Docker.dev 文件中的 Docker 映像的 npm 包有关，步骤 4 - npm install，实际上并不是 docker 警告。

无论是否容器化，这些包都是 react 应用程序的一部分，因此警告也会显示是否npm install从本地终端运行。

如果您希望隐藏警告，添加--silent（或者使用-sor --no-warnings），就像您在步骤 6 中的 Dockerfile 中所拥有的一样，将隐藏这些警告。
