Import Data on MongoDB using Docker-Compose

In my case, I put my json file into the data folder

mongoimport:
image: library/mongo:latest
container_name: my-import
volumes:
  - ./data/orders.json:/src/data/orders.json
command: mongoimport --host mongodb --db my-mongo --collection orders --file /src/data/orders.json


mongodb:
image: library/mongo:latest
container_name: my-mongo
ports:
  - 27017:27017
depends_on:
  - mongoimport
restart: always

You are seeing that Permission denied because you didn't mark the .sh file as executable. Just run chmod +x file.sh and then run again the whole docker-compose up.

I ended up removing the Dockerfile, adding the commands in a bash script, then calling the script from the docker-compose file. Used a script rather than one command in the docker-compose file because I'm importing several files thus several commands that are not shown in my example. I needed to use mongo:3.2.6 to make this work. There may be other versions but this one works for sure.

docker-compose.yml

version: '3'
services:
  mongodb:
    image: mongo:3.2.6
    ports:
      - 27017:27017

  mongo_seed:
    image: mongo:3.2.6
    links:
      - mongodb
    volumes:
      - ./mongo-seed:/mongo-seed
    command:
      /mongo-seed/import.sh

/mongo-seed/import.sh

#! /bin/bash

mongoimport --host mongodb --db test --collection census --type json --file /mongo-seed/census.json --jsonArray
