What methods exist for generating users in mongodb through a script?

Currently, I am in the process of configuring mongodb, and our servers are managed through puppet.

While I have successfully set up most components as required, I still need to create a user within the mongo database.

I am familiar with how to accomplish this task using the mongo shell by executing javascript commands such as:

db.addUser("username", "password"[, readOnly])

However, what eludes me is finding a concrete example demonstrating how to execute this in javascript. My ultimate objective is to add a user from the command line, preferably through a shell script.

If someone could provide:

a) references to reliable examples illustrating the use of javascript with MongoDB, and

b) guidance on how to achieve this through the command line?

Answer №1

When using MongoDB's cli, it provides guidance on how to utilize a JavaScript file

$ mongo --help
MongoDB shell version: 2.0.3
usage: mongo [options] [db address] [file names (ending in .js)]
...

usage: mongo [options] [db address] [file names (ending in .js)]

Here is an example:

$ echo 'db.addUser("guest", "passwordForGuest", true);' > file.js
$ mongo mydb file.js
MongoDB shell version: 2.0.3
connecting to: mydb
{ "n" : 0, "connectionId" : 1, "err" : null, "ok" : 1 }
{
    "user" : "guest",
    "readOnly" : true,
    "pwd" : "b90ba46d452e5b5ecec64cb64ac5fd90",
    "_id" : ObjectId("4fbea2b013aacb728754fe10")
}

Update:
db.addUser deprecated since 2.6
https://docs.mongodb.com/v2.6/reference/method/db.addUser/

Now, use db.createUser instead: 

// file.js
db.createUser(
  {
    user: "guest",
    pwd: "passwordForGuest",
    roles: [ { role: "read", db: "mydb" } ]
  }
)

$ mongo mydb file.js

Answer №2

Check out this sleek and straightforward alternative:

echo 'db.createUser({user:"<username>", pwd:"<password>", roles:["readWrite"]});' | mongo <database>

Verified to work with MongoDB version 2.4.8

Answer №3

Although AD7six has addressed a similar issue, I encountered a scenario where I was able to access a user with database authentication 'test'.
To resolve this, I included a command before creating the user to specify the authentication database.

db = db.getSiblingDB('myCustomDatabase');
db.createUser(
 {
   user: "myNewUser",
   pwd: "mySecurePwd",
   roles: [
    { role: "readWrite", db: "myCustomDatabase" }
   ]
 }
);

Note that the authentication database may differ from the database assigned to the user. Using the JavaScript command "getSiblingDB(dataBase)" serves as an alternative to the Shell command "use dataBase".
