使用Phusion Passenger运行Rails，目前遇到postgres问题，每当我运行build命令时，我都会收到此错误：
PG::ConnectionBad (could not connect to server: No such file or directory
Is the server running locally and accepting
connections on Unix domain socket "/var/run/postgresql/.s.PGSQL.5432"?
):

任何帮助都非常感谢，我仍然掌握着Docker并致力于生产。
它试图连接到Unix域套接字的事实指向Rails应用程序中的配置问题。你的docker-compose.yml中有DATABASE_URL，但它被注释掉了 - 取消注释至少应该更接近（应用程序应该至少尝试开始连接到postgres.local而不是自Postgres运行后不会存在的本地Unix域套接字在一个单独的容器中）。
