Mongo连接拒绝了ECCONREFUSED
我有一个应用程序在Docker容器中运行。 在日志中容器启动数据库，并让它监听端口27017
在后来的应用程序，build立了其余的网站，它试图连接到该端口上的数据库，并失败ECONNREFUSED 127.0.0.1:27017
我想这可能是一个很基本的东西，我不理解这里，但帮助将不胜感激

mongodb: image: mongo:3.2 web: build: . environment: - MONGODB_URL=mongodb://mongodb:27017/mern-starter
然后在您的应用程序中，您可以使用MONGODB_URL环境variables来连接MongoDB。
