About

This is a Docker image for MongoDB which tracks the upstream official image.

How to use

As this is based on the library MongoDB image, see their README on The Docker Hub.

Authentication

Authentication can be enabled by setting the environment variable MONGODB_AUTH_ENABLED=1

In order for authentication to work, you will need to define an admin user or a set of users:

Admin user

You can create an admin user that has a userAdminAnyDatabase role via setting the environment variables:

• MONGODB_ADMIN_USER=
• MONGODB_ADMIN_PWD=

Note this Admin user with it's roll can only add other users to databases, not operate on the db collections.

If you need the admin user to have further roles like root, then create it using the Set of users method instead.

Set of users

You can create one or more users with additional roles, and in specific databases using JSON set in the environment variable MONGODB_USERS.

The JSON takes the form of an array of user objects, with the user objects following the specification that MongoDB's db.createUser() takes, with a minor addition of a database field, which defines what database the user is created in. If not supplied, the user will be added to the admin database.

e.g.

MONGODB_USERS='[
  {
    "user": "fred"
    "pwd": "123"
    "roles": [
      "readWrite",
      {
          "role": "read",
          "db": "janesdb"
      }
    ],
    "database": "fredsdb"
  },
]'

MONGODB_USERS='[
  {
    "user": "admin"
    "pwd": "123"
    "roles": [
      "root",
    ]
  },
]'

The reason for the additional database field is that MongoDB authentication is run against the db that the connection authenticates with, which for applications needn't be the admin db. A role's db however applies on operations in a db after authentication.
