[SOLVED] How to use Azure Managed Identity to access Azure Cosmos db on ruby on rails?

How to use Azure Managed Identity to access Azure Cosmos db on ruby on rails?

I have a ruby on rails application. I am using mongoid gem to connect to Azure cosmos db for mongo service on azure. Currently, I use username and password for authentication. Instead of using username and password for authentication, I want to use Azure Managed Identity.

In config/mongoid.yml file, following is the configuration

      options:
        user: <%= ENV['USERNAME'] %>
        password: <%= ENV['PASSWORD'] %>
        ssl: true
        auth_source: admin

Also, documentation of mongoid says, qouting the documentation here:-

Change the default authentication mechanism. Valid options are: :scram, :mongodb_cr, :mongodb_x509, and :plain. Note that all authentication mechanisms require username and password, with the exception of :mongodb_x509. Default on mongoDB 3.0 is :scram, default on 2.4 and 2.6 is :plain.

I have gone through the following documentation, where they have used AzureIdentity library for .Net, Java, Javascript to authenticate using MI. I am looking for the same for ruby on rails.

Could anyone please help/guide me with this?

Solution

Currently Cosmos DB for Mongo DB(Both vCore and RU mode) do not support Managed Identity. The documentation that you're seeing is applicable to Cosmos DB NOSQL API only.
