Docker – PG :: ConnectionBad
用Phusion Passenger运行Rails，目前遇到postgres问题，每当我运行构build命令时，我得到这个错误：
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"? ): 我的Dockerfile

任何帮助真的很感激，我仍然得到了Docker的工作和生产。
它尝试连接到Unix域套接字的事实指向了Rails应用程序中的configuration问题。 你docker-compose.yml有DATABASE_URL ，但是它被注释掉了 – 取消注释至less应该接近（应用程序应该至less试图开始连接到postgres.local而不是本地Unix域套接字，因为Postgres在单独的容器中运行而存在）。
