Setting up MongoDB with Docker

04/05/2019 — 1 Min Read — In Development

One of my friends asked for help setting up a MongoDB with docker, so I threw together this gist. This sets up mongo with authentication enabled, which is really important (and overlooked in many tutorials). It also includes a container you can use to do nightly backups to S3.

version: "2"
services:
  mongo:
    image: mckernanin/mongo-auth:4.0.8
    environment:
      AUTH: "yes"
      MONGODB_ADMIN_USER: admin
      MONGODB_ADMIN_PASS: '**********' # set your admin password here
      MONGODB_APPLICATION_DATABASE: appname # give the db a name
      MONGODB_APPLICATION_USER: application
      MONGODB_APPLICATION_PASS: '**********' # set your application password here
    ports:
      - 27017:27017
    volumes:
      - ~/.mongo:/data/db # this persists your mongo data to disk outside of docker
  # mongo-backup: # automated backups to s3
  #   image: lgatica/mongodump-s3
  #   environment:
  #     MONGO_URI: mongodb://application:**********@mongodb/appname # connection string based on above config
  #     AWS_ACCESS_KEY_ID: '**********' # aws access key
  #     AWS_SECRET_ACCESS_KEY: '**********' # aws secret key
  #     AWS_DEFAULT_REGION: us-east-2 # aws region
  #     S3_BUCKET: '**********' # aws bucket name
  #     BACKUP_CRON_SCHEDULE: 0 2 * * *
  #     S3_PATH: '**********' # aws bucket path
  #   links:
  #     - mongo:mongodb
