1. Deploy the variant-ui helm chart on Digital Ocean Kubernetes Service


    To deploy a Helm chart to a Kubernetes cluster on Digital Ocean using Pulumi, you'll need to do a few things:

    1. Setup a Kubernetes cluster on Digital Ocean.
    2. Install the Helm CLI tool locally.
    3. Use Pulumi's Kubernetes provider to create a Helm chart resource in your Pulumi program.

    First, ensure you have Pulumi installed and configured with access to your Digital Ocean account. You also need to have kubectl and Helm set up on your machine to interact with Kubernetes clusters and manage Helm charts.

    The Pulumi program below is written in TypeScript. It sets up a Digital Ocean Kubernetes cluster and subsequently deploys the variant-ui Helm chart.

    We'll be using @pulumi/digitalocean to create a Kubernetes cluster and @pulumi/kubernetes to deploy the Helm Chart to the cluster.

    Here's how you can accomplish the task, step by step:

    import * as digitalocean from "@pulumi/digitalocean"; import * as kubernetes from "@pulumi/kubernetes"; import * as pulumi from "@pulumi/pulumi"; // Step 1: Create a new DigitalOcean Kubernetes cluster const cluster = new digitalocean.KubernetesCluster("do-cluster", { // Specify the region for the cluster region: digitalocean.Regions.NYC1, // Specify the version of Kubernetes version: "1.21.5-do.0", // Define the node pool nodePool: { size: digitalocean.DropletSlugs.DropletS2VCPU2GB, name: "default-pool", nodeCount: 2, }, }); // Step 2: Use the DigitalOcean Kubernetes cluster as our provider const k8sProvider = new kubernetes.Provider("do-k8s", { kubeconfig: cluster.kubeConfigs[0].rawConfig, }); // Step 3: Deploy the variant-ui Helm chart on the cluster const chart = new kubernetes.helm.v3.Chart("variant-ui-chart", { chart: "variant-ui", version: "1.0.0", // Replace with the specific chart version you need // If the chart is not from the stable Helm chart repository // you may need to specify the repository URL. fetchOpts: { repo: "https://charts.example.com/", // Put the URL of your Helm chart repository here }, }, { provider: k8sProvider }); // Output the kubeconfig to connect to the cluster with kubectl export const kubeconfig = cluster.kubeConfigs[0].rawConfig; // After running `pulumi up`, you can interact with the cluster using `kubectl` as follows: // $ pulumi stack output kubeconfig > kubeconfig.yaml // $ KUBECONFIG=./kubeconfig.yaml kubectl get po -A

    A detailed breakdown of this program:

    1. We import the Pulumi packages needed to interact with DigitalOcean and Kubernetes.
    2. We create a Kubernetes cluster on DigitalOcean using the KubernetesCluster resource. We specify the region, Kubernetes version, and the node pool configuration for this cluster.
    3. We use the kubeConfigs property of the created cluster to provide the kubeconfig to the Kubernetes provider instance, necessary for Pulumi to interact with our cluster.
    4. We set up the Chart resource, which represents the Helm chart we want to deploy. Here you specify the chart name, version, and repository.
    5. We export the kubeconfig so that you can use kubectl to interact with your Kubernetes cluster outside of Pulumi.

    To run this Pulumi program, save it to a file (e.g., index.ts), and ensure you have the Pulumi project set up. Then, run pulumi up. If you need more information on setting up a Pulumi project, visit the Pulumi documentation.

    Keep in mind you'll need to replace "https://charts.example.com/" with the actual repository URL where the variant-ui Helm chart is located. If the Helm chart is on a public repository included in Helm's default repositories, you can omit the fetchOpts entirely. You'll also want to ensure you use the correct chart and version name.
