Docker mongo image 'Connection refused' from other container

Question

I\'m new to docker. I\'m trying to create a MongoDB container and a NodeJS container. My file looks:

version: \'2\'
services:
  backend:
    image: node:5.11         


        

Answer 1

In your backend app, connect to mongodb:27017 instead of 127.0.0.1:27017. Where 'mongodb' is the name of your service within docker-compose.yml.
