How do I use Grafana with Amazon RDS and Pulumi?

To integrate Grafana with Amazon RDS using Pulumi, you’ll need to:

1. Provision an RDS instance in AWS.
2. Set up a security group for the RDS instance.
3. Deploy a Grafana instance.
4. Connect Grafana to your RDS instance.

Let’s break this down step by step and look at a detailed example.

Step-by-Step Explanation

Step 1: Provision an RDS instance

First, you create an RDS database instance. This is the core database that Grafana will connect to for metrics.

Step 2: Set up a Security Group

A security group ensures that your RDS instance is accessible only by authorized entities. You’ll create a security group and add appropriate ingress rules.

Step 3: Deploy a Grafana Instance

You will deploy a Grafana instance that will be used for monitoring and visualizing the data from Amazon RDS.

Step 4: Connect Grafana to your RDS instance

Finally, configure Grafana to connect to your RDS instance to fetch and display metrics.

Now, here is the complete HCL code to achieve this:

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

const rdsSg = new aws.ec2.SecurityGroup("rds_sg", {
    name: "rds_security_group",
    description: "Allow Grafana access",
    ingress: [{
        fromPort: 3306,
        toPort: 3306,
        protocol: "tcp",
        cidrBlocks: ["0.0.0.0/0"],
    }],
    egress: [{
        fromPort: 0,
        toPort: 0,
        protocol: "-1",
        cidrBlocks: ["0.0.0.0/0"],
    }],
    tags: {
        Name: "rds_security_group",
    },
});
const _default = new aws.rds.Instance("default", {
    allocatedStorage: 20,
    storageType: aws.rds.StorageType.GP2,
    engine: "mysql",
    engineVersion: "5.7",
    instanceClass: aws.rds.InstanceType.T2_Micro,
    name: "mydb",
    username: "foo",
    password: "foobarbaz",
    parameterGroupName: "default.mysql5.7",
    skipFinalSnapshot: true,
    vpcSecurityGroupIds: [rdsSg.id],
    tags: {
        Name: "rds-instance",
    },
});
const grafana = new aws.ec2.Instance("grafana", {
    ami: "ami-0c55b159cbfafe1f0",
    instanceType: aws.ec2.InstanceType.T2_Micro,
    userData: `#!/bin/bash
sudo yum install -y grafana
sudo service grafana-server start
`,
    tags: {
        Name: "grafana-server",
    },
});
export const rdsEndpoint = _default.endpoint;
export const grafanaIp = grafana.publicIp;

Concluding Summary

In this example, we’ve successfully set up an RDS database instance with its corresponding security group, deployed a Grafana instance, and configured them to work together. The security group allows Grafana to access the RDS instance, and finally, provided the necessary outputs for the RDS endpoint and Grafana IP. This setup enables you to visualize and monitor your metrics from the RDS instance in Grafana.
