Deploy the prometheus-operator-csv helm chart on Digital Ocean Kubernetes Service

Question

Pulumi · Accepted Answer

To deploy the Prometheus Operator helm chart on Digital Ocean Kubernetes Service using Pulumi, we will follow these steps:

1. Set up a Digital Ocean Kubernetes cluster.
2. Install the Prometheus Operator helm chart onto the cluster.

For setting up a Digital Ocean Kubernetes cluster, we will use the `digitalocean.KubernetesCluster` resource, which allows us to define and provision a Kubernetes cluster hosted on Digital Ocean.

Once the cluster is set up, we will use the `kubernetes.helm.v3.Chart` resource from Pulumi's `kubernetes` provider to deploy the Prometheus Operator from its Helm chart. The `Chart` resource allows Pulumi to manage Helm chart installations.

Below is a Pulumi program written in TypeScript that demonstrates how to accomplish this. Please make sure you have Pulumi installed, along with the necessary Pulumi TypeScript dependencies, and you have configured your Digital Ocean token and Kubernetes configuration to allow Pulumi to manage resources in your Digital Ocean account and deploy to the Kubernetes cluster.

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

// Create a Digital Ocean Kubernetes cluster.
const cluster = new digitalocean.KubernetesCluster("do-cluster", {
    // Set the region, version, and the node count.
    region: "nyc3",
    version: "latest", // Use the latest available version or specify a version
    nodePool: {
        name: "default-pool",
        size: "s-2vcpu-2gb",  // Select an appropriate size for your needs
        nodeCount: 2,         // Set the desired node count for the cluster
    },
});

// Get the kubeconfig from the newly created cluster to interact with it.
const kubeconfig = cluster.kubeConfigs[0].rawConfig;

// Deploy the Prometheus Operator helm chart on the Digital Ocean Kubernetes cluster.
const prometheusChart = new kubernetes.helm.v3.Chart("prometheus-operator", {
    chart: "prometheus-operator",
    version: "9.3.1", // Specify the chart version you want to deploy
    namespace: "monitoring", // Deploy into the "monitoring" namespace
    fetchOpts: {
        repo: "https://prometheus-community.github.io/helm-charts", // The helm chart repository
    },
    // Specify any custom values for the helm chart.
    // Here you would put chart-specific configurations.
    // For the prometheus-operator, refer to its documentation for available options.
    values: {
        // For example, set the service type to LoadBalancer to expose Prometheus
        // Note: These values
