我在Docker容器中运行了一个带有docker compose的应用程序。在日志中，容器启动数据库并使其侦听端口27017
稍后在应用程序中，构建了网站的其余部分后，它会尝试连接到该端口上的该数据库，并因ECONNREFUSED 127.0.0.1:27017而失败
我认为这可能是一件非常基本的事情，我不会在这里理解，但会非常感谢帮助

答案 0 :(得分：2)
您是否在docker-compose.yml中为MongoDB公开了端口27017？但是，如果您不想将MongoDB暴露给Internet（推荐的方式），您可以使用Docker的内部DNS连接MongoDB（docker-compose.yml的示例）：
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环境变量来连接MongoDB。
