Question

我对AWS生态系统完全陌生。我有一个仅带有socket.io服务器的NodeJS项目（没有express）。我正在尝试将其部署在Elastic Beanstalk上，因为有人提到它可以为我们处理所有设置。

我还碰到过一些文章，其中提到需要在根文件夹中有一个.ebextensions文件夹，并需要有一个container_command来更改代理标头，如下所示：

container_commands:
  enable_websockets:
    command: |
      sed -i '/\s*proxy_set_header\s*Connection/c \
              proxy_set_header Upgrade $http_upgrade;\
              proxy_set_header Connection "upgrade";\
              ' /tmp/deployment/config/#etc#nginx#conf.d#00_elastic_beanstalk_proxy.conf

但是我将上述文件添加到.ebextensions中，然后创建一个基本的Elastic Beanstalk应用程序，然后它不起作用：

步骤：

创建一个新的应用程序
选择平台-节点，平台分支-在64位Amazon Linux 2上运行的Node.js 12，平台版本5.2.1
选择“上传代码”并按代码zip文件添加
执行“创建应用程序”

此消息失败

Application deployment failed at 2020-09-20T07:17:01Z with exit status 1 and error: Engine execution has encountered an error.

下载所有日志时，我看到以下内容

在cfn-init-cmd.log

中

Command enable_websockets
sed: can't read /tmp/deployment/config/#etc#nginx#conf.d#00_elastic_beanstalk_proxy.conf: No such file or directory
Exited with error code 2

在cfn-init.log

中

有人可以用简单而简单的步骤说明我要使其运行所需要做的一切吗？

我是否需要进行任何配置更改（例如在任何其他端口上添加新的侦听器）？
我是否需要使用Platform Webhooks或类似here的内容。如果是，那怎么办？
我需要修改文件夹结构并自己写任何文件吗？

AWS Elastic Beanstalk上的Socket.io服务器未运行
