1. Deploy the kafka-topic-exporter helm chart on AWS EKS

    TypeScript

    To deploy the kafka-topic-exporter Helm chart on AWS EKS, we need to do the following:

    1. Provision an Amazon EKS (Elastic Kubernetes Service) cluster, which will run our Kubernetes workloads.
    2. Configure kubectl to connect to the new EKS cluster.
    3. Deploy the kafka-topic-exporter Helm chart to the EKS cluster.

    Provisioning the EKS Cluster with Pulumi:

    We'll use the eks Pulumi package to create an EKS cluster. This package encapsulates the details of creating an EKS cluster and provides a higher-level abstraction over AWS resources to simplify the process.

    Here's how we'll go about it:

    1. Define an EKS Cluster: We'll instantiate an EKS cluster with the required configurations.
    2. Configure Kubernetes Provider: We'll create a Kubernetes provider that knows how to communicate with the EKS cluster's API server.
    3. Deploy Helm Chart: We'll use the Kubernetes provider to deploy the kafka-topic-exporter Helm chart.

    Below is the complete TypeScript program for deploying a kafka-topic-exporter Helm chart on AWS EKS using Pulumi.

    import * as eks from "@pulumi/eks"; import * as pulumi from "@pulumi/pulumi"; import * as k8s from "@pulumi/kubernetes"; // Create an EKS cluster. // The `eks.Cluster` resource automatically creates the necessary IAM roles and networking infrastructure. const cluster = new eks.Cluster("my-cluster", { desiredCapacity: 2, // Specify the desired number of worker nodes minSize: 1, maxSize: 3, storageClasses: "gp2", // Use gp2 as the default storage class deployDashboard: false, // EKS dashboard is not recommended hence set to false }); // Export the kubeconfig so that kubectl and other Kubernetes tools can connect to the cluster. export const kubeconfig = cluster.kubeconfig; // Use the `k8s.Provider` resource with the kubeconfig obtained from the EKS cluster. // This provider will be used to deploy Helm charts to the cluster. const provider = new k8s.Provider("k8s-provider", { kubeconfig: cluster.kubeconfig.apply(JSON.stringify), }); // Deploy the kafka-topic-exporter Helm chart using the created Kubernetes provider. const kafkaTopicExporterChart = new k8s.helm.v3.Chart("kafka-topic-exporter", { chart: "kafka-topic-exporter", version: "1.0.0", // Ensure you specify the right chart version here fetchOpts: { repo: "https://charts.helm.sh/stable", // Replace with the Helm repository that hosts kafka-topic-exporter chart }, }, { provider: provider }); // Export the Helm chart deployment status export const kafkaTopicExporterStatus = kafkaTopicExporterChart.status;

    Explanation:

    • The eks.Cluster class is used to provision the EKS cluster. We specify the desired number of nodes (desiredCapacity), minimum number of nodes (minSize), and maximum number of nodes (maxSize). We also indicate that we want to use "gp2" as the default storage class and that we do not want to deploy the Kubernetes dashboard.

    • We export kubeconfig which is a configuration file necessary for kubectl and other Kubernetes tools to connect to the EKS cluster.

    • We create a k8s.Provider instance configured to use our EKS cluster's kubeconfig. This allows Pulumi to communicate with the Kubernetes API server of the EKS cluster.

    • We then deploy the kafka-topic-exporter Helm chart using the k8s.helm.v3.Chart class, passing it the chart name and version (You need to specify the actual chart version you intend to use). We also specify the repository URL that hosts the kafka-topic-exporter chart.

    • Finally, we export the status of the Helm chart deployment as kafkaTopicExporterStatus, which can be used for debugging in case the Helm deployment fails.

    To run this program:

    • Ensure AWS CLI is configured with appropriate credentials in your environment.
    • Install Pulumi CLI if it's not already installed.
    • Run pulumi up to preview and deploy the changes.
