MongoDB authentication through Docker

From Stackoverflow

If you take a look at:

• https://github.com/docker-library/mongo/blob/27f2722bb2ebd26354321adc8c3f19f7958529e1/3.4/Dockerfile
• https://github.com/docker-library/mongo/blob/27f2722bb2ebd26354321adc8c3f19f7958529e1/3.4/docker-entrypoint.sh

you will notice that there are two variables used in the docker-entrypoint.sh:

• MONGO_INITDB_ROOT_USERNAME
• MONGO_INITDB_ROOT_PASSWORD

You can use them to setup root user. For example you can use following docker-compose.yml file:

docker-compose.yml

version: '2'
services:
  mongodb:
  image: mongo:3.4.2
  environment:
      # provide your credentials here
      - MONGO_INITDB_ROOT_USERNAME=root
      - MONGO_INITDB_ROOT_PASSWORD=rootPassXXX
  ports:
    - "27017:27017"
  volumes:
    - mongodb:/data/db
      # if you wish to setup additional user accounts specific per DB or with different roles you can use following entry point
    - "$PWD/mongo-entrypoint/:/docker-entrypoint-initdb.d/"
  # no --auth is needed here as presence of username and password add this option automatically
  command: mongod
