How to create user in mongodb with docker-compose

Question

I\'m trying to create some kind of script that will create a docker with mongodb and automatically create a user.

I can usually manage my docker images with docker-c

Answer 1

add --noauth option to the mongo command

extract from my docker-compose.yml file

mongors:
  image: mongo:latest
  command: mongod --noprealloc --smallfiles --replSet mongors2 --dbpath /data/db --nojournal --oplogSize 16 --noauth
  environment:
    TERM: xterm
  volumes:
    - ./data/mongors:/data/db

Answer 2

file: docker-compose.yaml

mongo:
    image: mongo:latest
    volumes_from:
        - data
    ports:
        - "27017:27017"
    command: --auth

    container_name: "db_mongodb"

data:
    image: mongo:latest
    volumes:
        - /var/lib/mongo
        - ./setup:/setup
    command: "true"
    container_name: "db_mongodb_data"

file: .buildMongo.sh

#!/bin/sh
docker-compose down
docker-compose up -d
sleep 1
docker exec db_mongodb  mongo admin /setup/create-admin.js
docker exec db_mongodb  mongo myDb /setup/create-user.js -u admin -p admin --authenticationDatabase admin

The create-admin.js and create-user.js files are commands that you use using the mongo shell. So they must be easy for you to understand. The real direction is like the jzqa answer, "environment variables". So the question here is how to create a user. I think this answers that point at least, you can check the complete setup here https://github.com/Lus1t4nUm/mongo_docker_bootstrap
