【问题描述】：
我正在尝试在 Amazon ElasticBeanstalk 上部署一个多容器 docker rails/postgres/nginx 应用程序（我已尝试将 postgres 容器移动到 Amazon RDS，但相关的安全组没有被公开 - 导致另一个帖子） .每当我尝试为我的应用程序访问环境的 URL 时，我都会得到：
端口号无效：“tcp://172.17.0.2:5432”
我相信我正在遵循构建、标记和推送图像、压缩源包、正确配置 Dockerrun.aws.json 以及更新应用程序并将其部署到环境的所有步骤。我希望我已经在下面包含了所有相关文件和跟踪信息。任何见解将不胜感激。谢谢。
Dockerrun.aws.json：
