无法连接到Docker postgres容器-Scala

问题描述

我创建了一个名为Job-board的服务，我希望它运行并与postgres容器对话。我不确定是否应该使用sbt运行工作板？还是应该使用docker-compose来与Docker一起运行这两个服务？

何时使用SBT以及在容器中运行？

我一直收到以下连接错误，我尝试使用连接网址，但是没有运气。

我不确定application.config在这一切中起什么作用，以及它与dockerFile和docker-compose的关系。

如果您需要更多详细信息，这里是github存储库：https://github.com/fullStackRyan/job-board

解决方法

看起来您的postgre网址错误。根据此文档，我看不到Postgre.POSTGRES_URL环境var。 https://hub.docker.com/_/postgres

在工作板上：您的POSTGRES_URL应该看起来像 jdbc：{驱动程序}：// {主机}：{端口} / {db}
