1. Deploy the cluster-api-byoh helm chart on Digital Ocean Kubernetes Service


    To deploy the cluster-api-byoh Helm chart on the Digital Ocean Kubernetes Service, we will use Pulumi's DigitalOcean and Kubernetes providers. The DigitalOcean provider will be used to provision a Kubernetes cluster on Digital Ocean, and the Kubernetes provider will manage the deployment of the Helm chart onto that cluster.

    Here's how you'll accomplish this task with Pulumi TypeScript:

    1. Import the necessary Pulumi packages for DigitalOcean and Kubernetes.
    2. Provision a DigitalOcean Kubernetes (DOKS) cluster using the digitalocean.KubernetesCluster resource.
    3. Configure the Kubernetes provider to target the provisioned DOKS cluster.
    4. Deploy the cluster-api-byoh Helm chart using the kubernetes.helm.v3.Chart resource.

    Below is the Pulumi TypeScript program that executes the above steps:

    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", version: "latest", // Specify the Kubernetes version or use "latest" nodePool: { name: "default", size: "s-1vcpu-2gb", // Choose the size that fits your needs nodeCount: 2, // Number of nodes in the node pool }, }); // Step 2: Configure the Kubernetes provider to use the kubeconfig from the provisioned cluster const k8sProvider = new k8s.Provider("k8s-provider", { kubeconfig: cluster.kubeConfigs[0].rawConfig, }); // Step 3: Deploy the cluster-api-byoh Helm chart onto the DigitalOcean Kubernetes cluster const chart = new k8s.helm.v3.Chart("cluster-api-byoh-chart", { chart: "cluster-api-byoh", // The name of the chart // If the chart is from a custom repo, specify it with `repo` field version: "0.4.3", // The version of the Helm chart, specify as needed namespace: "default", // The Kubernetes namespace to deploy into }, { provider: k8sProvider }); // Export the cluster's kubeconfig and the service endpoint export const kubeconfig = cluster.kubeConfigs[0].rawConfig; export const chartServiceEndpoint = pulumi.interpolate`${chart.getStatus().apply(status => status.endpoint)}`;

    Explanation of the Pulumi program:

    • First, we're creating a new DigitalOcean Kubernetes cluster (digitalocean.KubernetesCluster) in the New York 1 (nyc1) region using the latest version of Kubernetes. The cluster will have a node pool with two nodes of the specified size.
    • Then, we configure a Kubernetes provider using the kubeconfig obtained from the newly created DOKS cluster, allowing us to deploy resources onto this cluster.
    • Finally, we deploy the cluster-api-byoh Helm chart using the k8s.helm.v3.Chart resource. Here, we specify the chart name and the version. If the chart is hosted on a custom Helm repository, you would also need to specify the repo field.

    The export statements at the end of the program output the raw kubeconfig and the endpoint of the deployed chart's service if it exists. This allows you to interact with your Kubernetes cluster using kubectl and access the deployed Helm chart's service, respectively.

    You will need to run this Pulumi program using the Pulumi CLI commands pulumi up to provision the DOKS cluster and deploy the Helm chart. Ensure you have the Pulumi CLI and DigitalOcean API access token configured prior to running the program.
