Using aws secretsmanager with grafana

Question

Pulumi · Accepted Answer

To integrate AWS Secrets Manager with Grafana for secure storage of credentials, we will first create a secret in AWS Secrets Manager using Pulumi. Then, we’ll configure Grafana to use that secret for its operational credentials. Pulumi allows you to manage infrastructure as code, making it easy to automate and reproduce setups.

### Creating a Secret in AWS Secrets Manager

First, we will create a secret in AWS Secrets Manager which will hold sensitive information that Grafana might need, such as database passwords or API keys. We will be using the `aws.secretsmanager.Secret` resource from the Pulumi AWS package to create a new secret.

### Integrating the Secret with Grafana

For integrating the secret with Grafana, typically you would update the Grafana configuration to reference the created secret. However, the details of this will depend on how you are running Grafana (e.g., as a standalone binary, Docker container, or within a Kubernetes cluster). For this example, we will assume you're deploying Grafana to an AWS EC2 instance and you will use the AWS SDK within Grafana to retrieve the secret at runtime.

Here is a basic Pulumi program written in TypeScript that creates a new secret in AWS Secrets Manager:

```typescript
import * as aws from "@pulumi/aws";

// Create a new secret in AWS Secrets Manager
const grafanaSecret = new aws.secretsmanager.Secret("grafanaSecret", {
    description: "Grafana secret (database password, API keys, etc.)",
});

// Create a new secret value in AWS Secrets Manager
const grafanaSecretValue = new aws.secretsmanager.SecretVersion("grafanaSecretValue", {
    secretId: grafanaSecret.id,
    secretString: JSON.stringify({
        databasePassword: "your-database-password",
        apiKey: "your-api-key",
    }),
});

// Export the ARN of the secret
export const secretArn = grafanaSecret.arn;
export const secretVersion = grafanaSecretValue.versionId;
```

This program will create a new secret with a name `grafanaSecret` and a `grafanaSecretValue` containing a JSON with `databasePassword` and `apiKey`. The actual values should be replaced with your sensitive data.

Note that we're exporting the ARN and version ID of the secret, which you would typically use in your Grafana configuration to reference the secret.

### Using the Secret in Grafana

In Grafana, you would reference the AWS Secret in your configuration or code through AWS SDK calls, by providing the secret ARN. Below is a pseudo code snippet that shows how you might retrieve a secret value in your Grafana application, assuming Grafana has the necessary AWS IAM permissions to access the secret:

```javascript
const AWS = require('aws-sdk');

// Configure AWS
AWS.config.update({region: 'your-region'});

// Create a Secrets Manager client
const client = new AWS.SecretsManager();

// Retrieve the secret value
client.getSecretValue({SecretId: 'arn-of-the-secret'}, function(err, data) {
    if (err) {
        console.log(err);
    } else {
        // Assuming that the secret was stored as plaintext JSON
        const secret = JSON.parse(data.SecretString);
        const databasePassword = secret.databasePassword;
        const apiKey = secret.apiKey;
        
        // Use these secrets in your Grafana configuration
        console.log(databasePassword, apiKey);
    }
});
```

This pseudo code should not be directly executed but should guide you on how to fetch the secrets for Grafana runtime configuration from the AWS Secrets Manager.

Remember, the keys you use in `JSON.stringify` when creating the secret must match the keys you expect in your Grafana application.

### Next Steps

After setting up the secret and integrating it with Grafana, make sure that the AWS IAM permissions are correctly configured to allow Grafana to access the Secrets Manager.

Also, ensure you handle your secret's lifecycle properly – rotate it regularly and audit access to it.

This example provides a starting point, but depending on your specific Grafana setup and how it's deployed, additional steps may be required to fully integrate Secrets Manager.
