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

    TypeScript

    Deploying a Kafka Connector using Helm on a Digital Ocean Kubernetes service involves several steps. Below is a Pulumi program in TypeScript that automates this process. First, you need to create a Kubernetes cluster on Digital Ocean. Then, you deploy the Kafka Connector using the Helm chart to the cluster.

    Before running the Pulumi program, ensure that you have Pulumi installed, and you are logged into the Pulumi service. Also, ensure that you have the required Digital Ocean credentials set up as environment variables or in your Pulumi configuration.

    Here's an explanation of each part of the Pulumi program:

    1. Digital Ocean Kubernetes Cluster Creation

      • We use the digitalocean.KubernetesCluster resource to create a new Kubernetes cluster in the specified region, with a given node count and size.
    2. Kafka Connector Helm Chart Deployment

      • We apply the kubernetes.helm.v3.Chart resource to deploy the Kafka Connector Helm chart to the newly created Kubernetes cluster. This resource will need the proper chart name and repository URL where the Kafka Connector Helm chart is located, which will have to be provided.

    Now, let's look at the Pulumi TypeScript program that will perform these tasks:

    import * as pulumi from "@pulumi/pulumi"; import * as digitalocean from "@pulumi/digitalocean"; import * as k8s from "@pulumi/kubernetes"; // Create a DigitalOcean Kubernetes cluster using the digitalocean.KubernetesCluster resource. const cluster = new digitalocean.KubernetesCluster("do-cluster", { region: "nyc1", version: "latest", nodePool: { name: "default", size: "s-1vcpu-2gb", nodeCount: 2, // Adjust the node count as required }, }); // Deploy the Kafka Connector using the Helm chart // This Pulumi resource applies the Helm chart to the Kubernetes cluster created above. const kafkaConnectorChart = new k8s.helm.v3.Chart("kafka-connector", { chart: "kafka-connector", version: "latest", // Specify the chart version you wish to deploy fetchOpts: { repo: "https://charts.bitnami.com/bitnami", // Replace with the correct Helm chart repository URL }, }, { provider: new k8s.Provider("k8s-provider", { kubeconfig: cluster.kubeConfigs[0].rawConfig }) }); // Export the cluster's kubeconfig export const kubeconfig = cluster.kubeConfigs[0].rawConfig;

    To use this program, create a new Pulumi project, replace the template's index.ts with the above code, and run pulumi up.

    Make sure to update the chart, version, and fetchOpts.repo fields with the actual Kafka Connector Helm chart name and repository URL. In this program, we used Bitnami Helm charts as an example, which is a popular source for Kubernetes applications.

    This program sets up a Kubernetes cluster and uses the Helm package manager to deploy the Kafka Connector. The kubeconfig is exported to enable interaction with the cluster using kubectl or other Kubernetes tools.

    Remember, to actually apply this Pulumi program, you will need to have the necessary permissions and access tokens for Digital Ocean and have the Pulumi CLI set up and authenticated on your machine. After running pulumi up, Pulumi will show you a preview of the resources that will be created and, upon confirmation, will proceed to make the actual changes.
