1. Deploy the s3-exporter helm chart on Digital Ocean Kubernetes Service


    To accomplish the task of deploying the s3-exporter Helm chart on DigitalOcean's Kubernetes service using Pulumi, we will proceed with the following steps:

    1. Provision a new DigitalOcean Kubernetes cluster.
    2. Deploy the s3-exporter Helm chart to the provisioned Kubernetes cluster.

    We will use two main Pulumi resources to achieve this:

    • digitalocean.KubernetesCluster (docs): This resource allows us to create a Kubernetes cluster on DigitalOcean. We will configure it with the desired region, version, node size, and count.

    • kubernetes.helm.v3.Chart (docs): This resource allows us to deploy a Helm chart on a Kubernetes cluster. Using this, we can install the s3-exporter Helm chart on our DigitalOcean Kubernetes cluster.

    Let's start by creating a new file called index.ts and import the necessary Pulumi packages. Then, we will define the required DigitalOcean's Kubernetes cluster and deploy the s3-exporter Helm chart using the Chart resource.

    Here's a complete Pulumi program written in TypeScript that will carry out these steps:

    import * as pulumi from "@pulumi/pulumi"; import * as kubernetes from "@pulumi/kubernetes"; import * as digitalocean from "@pulumi/digitalocean"; // Initialize a Pulumi project and set up DigitalOcean provider configuration according to your setup // Ensure you have the DigitalOcean token set up in your environment or Pulumi configuration // Step 1: Provision a new DigitalOcean Kubernetes cluster const cluster = new digitalocean.KubernetesCluster("do-cluster", { region: "nyc1", version: "1.21.5-do.0", nodePool: { name: "default", size: "s-2vcpu-2gb", nodeCount: 2, }, }); // Step 2: Deploy the `s3-exporter` Helm chart to the provisioned Kubernetes cluster const s3ExporterChart = new kubernetes.helm.v3.Chart("s3-exporter", { chart: "s3-exporter", fetchOpts: { repo: "https://helm.example.com/", // Replace with the actual repository URL containing `s3-exporter` }, }, { provider: new kubernetes.Provider("k8s-provider", { kubeconfig: cluster.kubeConfigs[0].rawConfig }) }); // Export the Kubernetes cluster name and the Kubeconfig export const kubeconfig = cluster.kubeConfigs[0].rawConfig; export const clusterName = cluster.name; // Note that you need to replace the `repo` value with the URL of the chart repository containing the `s3-exporter` chart

    This program does the following:

    • It imports the necessary Pulumi packages for working with Kubernetes and DigitalOcean.
    • A new DigitalOcean Kubernetes cluster named do-cluster is provisioned with the specified region, Kubernetes version, node size, and count.
    • The s3-exporter Helm chart is deployed to the Kubernetes cluster. The Helm chart should already be present in a Helm chart repository, and you will need to provide the URL of that repository.

    To run this Pulumi program, save the file and use the Pulumi CLI to create and preview the infrastructure stack:

    pulumi stack init dev pulumi up

    Ensure that you already have the DigitalOcean token configured in your environment or Pulumi configuration, as well as Helm CLI and Kubernetes CLI (kubectl) installed on your machine to interact with the cluster and Helm charts.
