与美洲狮和Nginx的Rails应用程序错误500访问
我有6个容器用微服务创build我自己的应用程序。 在这个项目中，我有一个示例应用程序。 当我访问url（ http://localhost:80/ ）时，浏览器返回错误消息500，
我们很抱歉，但是出了点问题。 如果您是应用程序所有者，请检查日志以获取更多信息。

谢谢您的帮助 ：）
在你的nginx conf中有一个错误：
try_files $uri/index.html $uri.html $uri @app;
尝试这个：
try_files $uri/index.html $uri.html $uri @rails;
好吧，我find了帮助@ehoffmann的问题
- 作为评论@ ehoffmann我有更改
app的rails。 - puma和nginx之间的通信必须通过tcp。 我改变了
docker-compose.yml行command: foreman startcommand: bundle exec puma -e development -p 3000
日志： Listening on tcp://0.0.0.0:3000
