Sample node and mongo app that uses docker

Docker Node MongoDB Example

Simple example of a dockerized Node/Mongo app

Quick Start

# Run in Docker
docker-compose up
# use -d flag to run in background

# Tear down
docker-compose down

# To be able to edit files, add volume to compose file
volumes: ['./:/usr/src/app']

# To re-build
docker-compose build

docker-node-mongo's Issues

Cant connect to existing mongo container

here is my docker-compose.yml:

version: '3'
services:
  app:
    container_name: docker-node-mongo
    restart: always
    build: .
    ports:
      - '3001:3000'
#    external_links:
#      - mongo
#  mongo:
#    container_name: mongo
#    image: mongo
#    ports:
#      - '27017:27017'

my index.js

mongoose
  .connect(
    'mongodb://127.0.0.1:27017/test2',
    { useNewUrlParser: true }
  )
  .then(() => console.log('MongoDB Connected'))
  .catch(err => console.log("errorErrorError"));

and this when i run docker container ls -a

this is the error when i type docker logs docker-node-mongo

docker-node-mongo | /bin/sh: 1: [npm: not found

Attempting to run docker-compose up seems to lead to an error showing that npm is not found.

Not too sure where to move forward from here. I am using Windows 10.
