DocumentDB (Replica Set)
Last modified on January 17, 2025
Overview
A datasource consists of a database resource and the credentials used to access it. This guide describes how to add a DocumentDB (replica set) database as a datasource in the StrongDM Admin UI.
Limitations
- The DocumentDB (replica set) resource type supports username/password authentication only.
- DocumentDB requires TLS to connect.
- DocumentDB does not support connection using service (SRV) records.
- AWS Directory Service integration is not supported.
Prerequisites
To add a datasource, make sure you have met the following prerequisites:
- Properly configure an account for your database resource. If you choose to store credentials for the resource with StrongDM, have those credentials ready. When not using StrongDM, set up a Secret Store integration and be able to enter the location of the secrets required to access the resource.
- The hostname or endpoint you enter for your resource must be accessible by at least one gateway or relay. To verify this, log in to the gateway or relay and use the
nc -zv <YOUR_HOSTNAME> <YOUR_PORT>Netcat command. For example, usenc -zv testdb-01.fancy.org 5432. If your gateway server can connect to this hostname, you can proceed.
-z flag to check for listeners without sending data and the -v flag to show verbose output. If you do not have Netcat, you can use a package manager such as APT (Advanced Package Tool) to install it. On Linux-based distributions, run apt-get install netcat.Add a Datasource
To add your new DocumentDB (replica set) database as a StrongDM datasource, use the following steps.
- Log in to the StrongDM Admin UI.
- Go to Resources > Datasources.
- Click Add datasource.
- Select DocumentDB (replica set) as the Datasource Type and set other configuration properties for your new database resource.
- Complete all required fields.
- Click Create to save the resource.
- Click the resource name to view status, diagnostic information, and setting details.
Resource properties
Configuration properties are visible when you add a datasource or when you click to view its settings. The following table describes the settings available for your DocumentDB (replica set) database.
| Property | Requirement | Description |
|---|---|---|
| Display Name | Required | Meaningful name to display the resource throughout StrongDM; exclude special characters like quotes (") or angle brackets (< or >) |
| Datasource Type | Required | Select DocumentDB (replica set) |
| Hostname | Required | Hostnames for your DocumentDB (replica set) resource; must be accessible to a gateway or relay; Host addresses and ports of all replica instances must be included, and separated by commas (for example, primary0:27017,replica1:27017,replica2:27017) |
| Bind Interface | Read only | Automatically generated IP address value in the 127.0.0.1 to 127.255.255.254 IP address range; default is 127.0.0.1; preferred bind interface value can be modified later under Settings > Port Overrides |
| Port Override | Read only | Automatically generated with a value between 1024-59999 as long as that port is not used by another resource; preferred port can be modified later under Settings > Port Overrides |
| Authentication Database | Required | Enter the name of the DocumentDB authentication database (for example, “admin”). |
| Secret Store | Optional | Credential store location; defaults to Strong Vault; learn more about Secret Store options |
| Username | Required | Username to utilize when connecting to this datasource; displays when Secret Store integration is not configured for your organization or when StrongDM serves as the Secret Store type |
| Password | Required | Password for the user connecting to this datasource; displays when Secret Store integration is not configured for your organization or when StrongDM serves as the Secret Store type |
| Username (path) | Required | Path to the secret in your Secret Store location (for example, path/to/credential?key=optionalKeyName where key argument is optional); required when using a non-StrongDM Secret Store type |
| Password (path) | Required | Path to the secret in your Secret Store location (for example, path/to/credential?key=optionalKeyName where key argument is optional); required when using a non-StrongDM Secret Store type |
| Replica Set | Required | The name of the Mongo replicaset |
| Connect to Replica? | Required | Enable to connect to a replica instead of the primary node; defaults to disabled |
| Resource Tags | Optional | Datasource tags consisting of key-value pairs <KEY>=<VALUE> (for example, env=dev) |
Secret Store options
By default, datasource credentials are stored in StrongDM. However, these credentials can also be saved in a secrets management tool.
Non-StrongDM options appear in the Secret Store dropdown if they are created under Network > Secret Stores. When you select another Secret Store type, its unique properties display. For more details, see Configure Secret Store Integrations.
Resource status
After a resource is created, the Admin UI displays that resource as unhealthy until the health checks run successfully. When the resource is ready, the Health icon indicates a positive, green status.
When the resource does not display a positive status, click the resource name to go to the Diagnostics tab and check for errors.
Test the Connection
After you have created the DocumentDB datasource, you can use the MongoDB Shell to test the connection to DocumentDB.
Run the following command to connect to the instance running on your localhost:
mongosh "mongodb://localhost:<PORT>/admin"Example:
mongosh "mongodb://localhost:37018/admin"Once connected, execute the following command to see the databases:
show dbs
