有没有人有资源或先前的例子来启动一个闪亮的 dockerized 应用程序，该应用程序是在 AWS EC2 实例上使用 golem 框架构建的？主要是，我可以使用一些帮助来配置 Dockerfile、shiny-server.conf 和 shiny-server.sh 文件。

该应用程序严重依赖 PostgreSQL 数据库来管理用户数据。我已经能够使用本地 docker 容器部署应用程序，但我不确定如何在 EC2 实例上导航启动。这主要是因为 golem 框架与 Shiny 应用程序的传统结构（server.r、ui.r、app.r）略有不同。我们需要对这个应用程序进行容器化，因为需要保留一个全局变量用户 ID，以及每个图像周围至少有四个唯一的用户数据集。我通常不会使用 AWS EC2 实例来为应用程序提供服务，但这是我们在项目团队中讨论的内容。

我不确定的另一个元素是 EC2 实例类型。图像约为 2.5Gb（并且还在增长）。该应用程序可能会为每位用户保存超过 500Mb 的数据。我们有大约 3,000 美元的托管费用，它应该至少持续两年（包括 RDS 成本）。一般来说，我不确定给定大小的应用程序的价格是否可行。

我的项目团队正在使用这种设置进入未知领域，因此非常欢迎任何建议。

这是我认为应该为 AWS EC2 实例设置的工作 Dockerfile。
