1. Deploy the xos-tester helm chart on Linode Kubernetes Engine

    TypeScript

    To deploy the xos-tester Helm chart on Linode Kubernetes Engine (LKE) using Pulumi, we need to perform a few steps:

    1. Set up the Linode provider to manage resources in Linode, specifically provisions an LKE cluster.
    2. Install the Helm chart into the LKE cluster using the Pulumi Kubernetes provider.

    We'll be using the @pulumi/linode and @pulumi/kubernetes packages to accomplish this. The @pulumi/linode package allows us to create and manage resources on Linode, including Kubernetes clusters, while the @pulumi/kubernetes package provides the necessary interfaces to deploy Helm charts on a Kubernetes cluster.

    Below is the TypeScript program that performs these two steps:

    import * as linode from "@pulumi/linode";
import * as k8s from "@pulumi/kubernetes";

// Step 1: Provision a Linode Kubernetes Engine cluster
const cluster = new linode.LkeCluster("xos-tester-cluster", {
    k8sVersion: "1.18", // Specify the desired Kubernetes version
    region: "us-central", // Specify the desired region
    nodePools: [{
        type: "g6-standard-2", // Type of node in Linode to use
        count: 1, // Number of nodes to deploy
    }],
});

// Step 2: Deploy the xos-tester Helm chart into the LKE cluster.
const kubeConfig = cluster.kubeconfig.apply(JSON.parse);
const k8sProvider = new k8s.Provider("k8s-provider", {
    kubeconfig: kubeConfig.rawConfig, // Use the kubeconfig from the created LKE cluster for our Kubernetes provider
});

const chart = new k8s.helm.v3.Chart("xos-tester", {
    chart: "xos-tester", // Chart name, assuming this chart is available in the default Helm repositories.
    // If the chart is located in a custom repository, you must specify `repo` attribute as well.
    version: "0.1.0", // Specify the chart version if necessary
    // You can also specify `values` here to provide a custom configuration for the Helm chart.
    // example:
    // values: { 
    //   service: { 
    //     type: "LoadBalancer" 
    //   } 
    // }
}, { provider: k8sProvider });

// Export the cluster's kubeconfig and the service's external IP to access xos-tester
export const kubeconfig = cluster.kubeconfig;
export const serviceExternalIp = chart.getResourceProperty("v1/Service", "xos-tester", "status").apply(status => status.loadBalancer.ingress[0].ip);

    Explanation

    In the script above:

    • We create an LKE cluster with the desired Kubernetes version in a selected region and with a specified node type and count.
    • We extract the raw kubeconfig for the created LKE cluster using Pulumi's apply function, which allows us to work with the data once the cluster is created.
    • We instantiate a Pulumi Kubernetes provider that uses the cluster's kubeconfig. This provider will be used for our Helm chart deployment.
    • We deploy the xos-tester Helm chart using the Chart resource from the @pulumi/kubernetes package. If needed, customize the chart by adding a values object corresponding to its values.yaml file.
    • Finally, we export the kubeconfig for the cluster and the external IP address for the service created by the Helm chart. The external IP is extracted from the status of the Service resource, assuming that the chart deploys a LoadBalancer service named xos-tester.

    Please customize the Kubernetes version, region, node types, and Helm values as necessary for your specific requirements. You should also ensure you have the requisite access to Linode and a Pulumi account set up before running this code. Once you have your Pulumi CLI configured with the required credentials, you can run pulumi up to deploy this program.
