1. Deploy the kafka-kraft-on-k8s helm chart on Digital Ocean Kubernetes Service

    TypeScript

    To deploy the kafka-kraft-on-k8s Helm chart on DigitalOcean Kubernetes Service using Pulumi, we'll follow these steps:

    1. Create a Kubernetes Cluster: We'll start by setting up a new Kubernetes cluster on DigitalOcean. We'll need to specify details like the region, node size, and number of nodes.

    2. Install the Helm Chart: Once we have a Kubernetes cluster, we'll install the kafka-kraft-on-k8s Helm chart. We'll use the Pulumi Kubernetes provider to deploy Helm charts to our cluster.

    Here is the TypeScript code for Pulumi to accomplish this, with comments explaining each step:

    import * as pulumi from "@pulumi/pulumi"; import * as digitalocean from "@pulumi/digitalocean"; import * as k8s from "@pulumi/kubernetes"; // Step 1: Create a new DigitalOcean Kubernetes cluster const cluster = new digitalocean.KubernetesCluster("do-cluster", { // Specify the region where the cluster will be created: region: digitalocean.Regions.NYC1, // Define the version of Kubernetes to use: version: "latest", // Define the node pool for the Kubernetes cluster: nodePool: { name: "default", size: "s-2vcpu-2gb", // Choose the instance size nodeCount: 2, // Define the number of nodes in the node pool }, }); // Create a Kubernetes provider instance using the kubeconfig from DigitalOcean cluster we created const k8sProvider = new k8s.Provider("do-k8s-provider", { kubeconfig: cluster.kubeConfigs[0].rawConfig, }); // Step 2: Install the kafka-kraft-on-k8s Helm chart on the cluster const kafkaHelmChart = new k8s.helm.sh.v3.Chart("kafka-kraft", { chart: "kafka-kraft-on-k8s", // Specify the Helm repository containing the chart here. // Since the snippet does not contain a specific repo, we'll presume it's from a well-known Helm chart repository. // You'll need to replace `CHART_REPO_URL` with the actual repository URL where the chart is located. fetchOpts: { repo: "CHART_REPO_URL" }, // You can specify additional values here if needed for configuring the Kafka setup. }, { provider: k8sProvider }); // Export the kubeconfig and cluster details to access the cluster. export const kubeConfig = cluster.kubeConfigs[0].rawConfig; export const clusterName = cluster.name; export const clusterEndpoint = cluster.endpoint;

    This program does the following:

    1. It creates a new Kubernetes cluster on DigitalOcean in the NYC1 region with a specified node size and count.

    2. It then sets up a Pulumi Kubernetes provider that targets our newly created DigitalOcean cluster using the kubeconfig obtained from the cluster.

    3. Lastly, it deploys the kafka-kraft-on-k8s Helm chart to the Kubernetes cluster using our custom Pulumi Kubernetes provider.

    Please note that in this program:

    • digitalocean.KubernetesCluster is the Pulumi resource used to create and manage a DigitalOcean Kubernetes cluster, which is documented here.

    • k8s.helm.sh.v3.Chart is the resource type from the Pulumi Kubernetes provider used to install Helm charts onto a Kubernetes cluster, and you can find more information here.

    Before running this Pulumi program, ensure you have set up:

    • Pulumi CLI and necessary software installed on your machine.
    • DigitalOcean access token configured so that Pulumi can authenticate with your DigitalOcean account.

    The CHART_REPO_URL placeholder in the code represents the repository URL where the kafka-kraft-on-k8s Helm chart is located; you will need to replace this with the actual URL.

    When this program is run by using the pulumi up command, it will provision the resources defined in the code. After successful deployment, you will have a running Kafka cluster on DigitalOcean Kubernetes Service, and the output will provide you with connection details like the Kubernetes cluster name and endpoint URL.
