Import data to MongoDB

If you want to import/restore or to do something else before using mongo db in your application, you can look at the following example.

You just need to create Dockerfile for mongo seed service and provide the command to prepare mongo db. In this case it’s command mongoimport

Dockerfile mongo_seed

FROM mongo
COPY init.json /init.json
CMD mongoimport --host mongodb --db exampleDb --collection contacts --type json --file /init.json --jsonArray

Looking around

In the root of this repository you’ll find a file named docker-compose.yml. Let’s quickly review the contents of this file:

docker-compose.yml

version: '3'
services:
  mongodb:
    image: mongo
    command: mongod --smallfiles
    ports:
      - 27017

  mongo_seed:
    image: ${{mongo_seed}}
    links:
      - mongodb

  client:
    image: ${{build_prj}}
    links:
      - mongodb
    ports:
      - 9000
    environment:
      - MONGO_URI=mongodb:27017/exampleDb
