MongoDB Atlas Database Secrets Engine

MongoDB Atlas is one of the supported plugins for the database secrets engine. This plugin generates database credentials dynamically based on configured roles for MongoDB Atlas databases. It cannot support rotating the root user's credentials because it uses a public and private key pair to authenticate.

See the database secrets engine docs for more information about setting up the database secrets engine.

Capabilities

Setup

1. Enable the database secrets engine if it is not already enabled:

   $ vault secrets enable database
   Success! Enabled the database secrets engine at: database/
   

   Copy

   By default, the secrets engine will enable at the name of the engine. To enable the secrets engine at a different path, use the -path argument.

2. Configure Vault with the proper plugin and connection information:

   $ vault write database/config/my-mongodbatlas-database \
       plugin_name=mongodbatlas-database-plugin \
       allowed_roles="my-role" \
       public_key="jmskfortvf" \
       private_key="ea6acbc7-8a30-4a3f-812e-6f869c08bcd1" \
       project_id="4f96cad208574fd14aa8dda3a"
   

   Copy

3. Configure a role that maps a name in Vault to a MongoDB Atlas command that executes and creates the database user credential:

   $ vault write database/roles/my-role \
       db_name=my-mongodbatlas-database \
       creation_statements='{"database_name": "admin","roles": [{"databaseName":"admin","roleName":"atlasAdmin"}]}' \
       default_ttl="1h" \
       max_ttl="24h"
   Success! Data written to: database/roles/my-role
   

   Copy

Usage

After the secrets engine is configured and a user/machine has a Vault token with the proper permissions, it can generate credentials.

1. Generate a new credential by reading from the /creds endpoint with the name of the role:

   $ vault read database/creds/my-role
   Key                Value
   ---                -----
   lease_id           database/creds/my-role/2f6a614c-4aa2-7b19-24b9-ad944a8d4de6
   lease_duration     1h
   lease_renewable    true
   password           FBYwnnh-fwc0quxtKf11
   username           v-my-role-DKbQEg6uRn
   

   Copy
