1. Deploy the s3-exporter helm chart on Linode Kubernetes Engine


    To deploy the s3-exporter Helm chart on Linode Kubernetes Engine using Pulumi, we'll proceed with the following steps:

    1. Set up the Linode Kubernetes Engine (LKE) Cluster: We'll create and configure a Kubernetes cluster within Linode's cloud using Pulumi's Linode provider.

    2. Configure Kubernetes Provider: Once the cluster is created, we'll configure Pulumi to use the Kubernetes provider pointing to the LKE cluster. This involves setting up the Kubeconfig so that Pulumi can communicate with the cluster.

    3. Deploy the Helm Chart: With the Kubernetes provider configured, we will define a Helm chart resource that points to the s3-exporter chart. We'll need to specify the Helm repository where the chart can be found or its location if it's already packaged.

    To follow these steps, make sure you have Pulumi and Linode CLI installed and configured appropriately on your local machine.

    Now, let's start with the code that performs these steps:

    import * as linode from '@pulumi/linode'; import * as k8s from '@pulumi/kubernetes'; import * as pulumi from '@pulumi/pulumi'; // Step 1: Create a Linode Kubernetes Engine Cluster const cluster = new linode.LkeCluster("my-cluster", { label: "my-cluster", k8sVersion: "1.18", // Specify the desired Kubernetes version region: "us-central", // Specify the preferred Linode region nodePools: [{ type: "g6-standard-2", // Specify the type of Linode instances for your node pool count: 2, // Specify the number of nodes in the node pool }], }); // Step 2: Configure Kubernetes Provider to point to the LKE cluster // This involves creating a Kubeconfig file that Pulumi can use to communicate with the Linode Kubernetes Engine const kubeconfig = cluster.kubeconfig.apply((e) => e.rawConfig); // Step 3: Deploy the s3-exporter Helm chart // Assuming the chart is available in a public repository, you set the repository URL and the chart name const s3ExporterChart = new k8s.helm.v3.Chart("s3-exporter", { chart: "s3-exporter", // Replace with the correct chart name version: "1.0.0", // Specify the Helm chart version fetchOpts: { repo: "http://helm-repo-url", // Replace with the Helm repository URL where s3-exporter is hosted }, values: { // Provide any configuration options for the s3-exporter Helm chart // For instance: service: { type: "ClusterIP", }, }, }, { provider: new k8s.Provider("k8s", { kubeconfig }) }); // Export the Kubeconfig and the Kubernetes Cluster endpoint to access the cluster export const kubeconfigOutput = kubeconfig; export const clusterEndpoint = cluster.apiEndpoints.apply(e => e[0].endpoint);

    This TypeScript code does the following:

    • Defines an LKE cluster resource with a given label, Kubernetes version, region, and node pool configuration.
    • Obtains the kubeconfig file from the newly created cluster, which is necessary for the Kubernetes provider to communicate with the LKE cluster.
    • Creates a new Helm chart deployment of s3-exporter using the k8s.helm.v3.Chart class. Note that the Helm chart name and repository URL need to be specified correctly for this to work. Additionally, any required configurations for the Helm chart can be provided in the values object.
    • Exports the Kubeconfig file and the cluster endpoint as outputs, which can be used to interact with the Kubernetes cluster using kubectl or another Kubernetes client.

    Once you run this Pulumi program, it will provision the necessary resources in Linode and deploy the s3-exporter Helm chart onto the LKE cluster. You can find more details on using Helm charts with Pulumi in the Pulumi documentation for Helm Charts.
