MongoDB Database Plugin HTTP API

The MongoDB database plugin is one of the supported plugins for the database secrets engine. This plugin generates database credentials dynamically based on configured roles for the MongoDB database.

Configure Connection

In addition to the parameters defined by the Database Backend, this plugin has a number of parameters to further configure a connection.

Method	Path	Produces
POST	/database/config/:name	204 (empty body)

Parameters

• connection_url (string: <required>) – Specifies the MongoDB standard connection string (URI). This field can be templated and supports passing the username and password parameters in the following format {{field_name}}. A templated connection URL is required when using root credential rotation.
• write_concern (string: "") - Specifies the MongoDB write concern. This is set for the entirety of the session, maintained for the lifecycle of the plugin process. Must be a serialized JSON object, or a base64-encoded serialized JSON object. The JSON payload values map to the values in the Safe struct from the mgo driver.
• username (string: "") - The root credential username used in the connection URL.
• password (string: "") - The root credential password used in the connection URL.

Sample Payload

{
  "plugin_name": "mongodb-database-plugin",
  "allowed_roles": "readonly",
  "connection_url": "mongodb://{{username}}:{{password}}@mongodb.acme.com:27017/admin?ssl=true",
  "write_concern": "{ \"wmode\": \"majority\", \"wtimeout\": 5000 }",
  "username": "admin",
  "password": "Password!"
}

Sample Request

$ curl \
    --header "X-Vault-Token: ..." \
    --request POST \
    --data @payload.json \
    http://127.0.0.1:8200/v1/database/config/mongodb

Statements

Statements are configured during role creation and are used by the plugin to determine what is sent to the database on user creation, renewing, and revocation. For more information on configuring roles see the Role API in the database secrets engine docs.

Parameters

The following are the statements used by this plugin. If not mentioned in this list the plugin does not support that statement type.

• creation_statements (string: <required>) – Specifies the database statements executed to create and configure a user. Must be a serialized JSON object, or a base64-encoded serialized JSON object. The object can optionally contain a "db" string for session connection, and must contain a "roles" array. This array contains objects that holds a "role", and an optional "db" value, and is similar to the BSON document that is accepted by MongoDB's roles field. Vault will transform this array into such format. For more information regarding the roles field, refer to MongoDB's documentation.

• revocation_statements (string: "") – Specifies the database statements to be executed to revoke a user. Must be a serialized JSON object, or a base64-encoded serialized JSON object. The object can optionally contain a "db" string. If no "db" value is provided, it defaults to the "admin" database.

Sample Creation Statement

{
  "db": "admin",
  "roles": [
    {
      "role": "read",
      "db": "foo"
    }
  ]
}
