Deploy the cloudwatch-agent-prometheus helm chart on Digital Ocean Kubernetes Service

Question

Pulumi · Accepted Answer

To deploy the cloudwatch-agent-prometheus Helm chart on a DigitalOcean Kubernetes Service (DOKS) cluster using Pulumi, we will proceed with the following steps:

1. **Set up a DigitalOcean Kubernetes Cluster**: We will define a `digitalocean.KubernetesCluster` resource to provision a Kubernetes cluster in DigitalOcean.
2. **Install the Helm Chart**: We will use the `kubernetes.helm.v3.Chart` resource to deploy the cloudwatch-agent-prometheus Helm chart to the Kubernetes cluster we just provisioned. It's important to note that the cloudwatch-agent-prometheus Helm chart is typically designed to be deployed to an Amazon EKS cluster for integration with AWS CloudWatch, not a DOKS cluster. However, you may customize the Helm chart accordingly for it to work with other monitoring solutions or for educational purposes.

Let's begin with the Pulumi program in TypeScript to achieve these. The following Pulumi program assumes you've already set up Pulumi and have configured access to DigitalOcean by setting up the relevant Pulumi stack configs and environment variables for authentication.

```typescript
import * as pulumi from "@pulumi/pulumi";
import * as digitalocean from "@pulumi/digitalocean";
import * as k8s from "@pulumi/kubernetes";

// Step 1: Provision a DigitalOcean Kubernetes cluster.
const cluster = new digitalocean.KubernetesCluster("do-cluster", {
    region: "nyc1", // Choose a region that is close to you.
    version: "latest", // Use the latest version of Kubernetes.
    nodePool: {
        name: "default-pool",
        size: "s-2vcpu-2gb", // Size of the Droplets (DigitalOcean VMs).
        nodeCount: 2, // Number of nodes in the node pool.
    },
});

// Step 2: Deploy the cloudwatch-agent-prometheus Helm chart to the cluster.
const kubeconfig = cluster.kubeConfigs[0].rawConfig; // Get the kubeconfig from the cluster resource.
const provider = new k8s.Provider("k8s-provider", { // Create a k8s provider with the kubeconfig.
    kubeconfig: kube
