1. Deploy the istio-helloworld helm chart on Linode Kubernetes Engine


    To deploy the Istio helloworld Helm chart on Linode Kubernetes Engine using Pulumi, you'll need to follow these steps:

    1. Set up a Linode Kubernetes Engine (LKE) cluster: You first need to create a Kubernetes cluster in Linode where your application will run.

    2. Install Istio on your cluster: You may need to install Istio service mesh on your LKE cluster before deploying the helloworld application. This often involves applying Istio manifests or using the Istio operator.

    3. Deploy the helloworld Helm chart: After you have Istio running, you will deploy the helloworld Helm chart. This will set up the sample application within the Istio service mesh.

    Below is a Pulumi program that performs these tasks. This example assumes you have Linode provider configured and the necessary Helm chart details for helloworld are known (e.g., chart version, repository).

    In this program, we will use the @pulumi/linode, @pulumi/kubernetes, and @pulumi/kubernetes/helm/v3 packages. The @pulumi/linode package allows us to manage Linode resources, including Kubernetes clusters. The @pulumi/kubernetes package helps us interact with Kubernetes clusters, apply manifests, or set up configurations. The @pulumi/kubernetes/helm/v3 package is specifically utilized to deploy Helm charts to our Kubernetes cluster.

    Here is the TypeScript code for Pulumi:

    import * as linode from "@pulumi/linode"; import * as k8s from "@pulumi/kubernetes"; import * as helm from "@pulumi/kubernetes/helm/v3"; // Step 1: Create a Linode Kubernetes Engine cluster const lkeCluster = new linode.LkeCluster("my-lke-cluster", { label: "my-lke-cluster", region: "us-central", k8sVersion: "1.20", tags: ["pulumi"], pool: { type: "g6-standard-2", count: 3, }, }); // Step 2: Set up the Kubeconfig for the LKE cluster const kubeconfig = lkeCluster.kubeconfig.apply(JSON.stringify); // Step 3: Use Pulumi Kubernetes provider to interact with the LKE cluster const k8sProvider = new k8s.Provider("k8s-provider", { kubeconfig: kubeconfig, }); // Step 4: Install the Istio `helloworld` Helm chart const helloworldChart = new helm.Chart("istio-helloworld", { chart: "helloworld", version: "1.0.0", // specify the correct chart version fetchOpts: { repo: "https://istio-release.storage.googleapis.com/charts", // specify the correct Helm repo URL }, namespace: "default", }, { provider: k8sProvider }); // Export the LKE cluster's Kubeconfig and Helm chart resources export const clusterKubeconfig = kubeconfig; export const helloworldChartResources = helloworldChart.resources;

    This Pulumi program will create a new Linode Kubernetes Engine cluster, configure the Kubernetes provider to interact with the cluster, and then deploy the Istio helloworld Helm chart to that cluster. The export statements at the end of the program will output the kubeconfig for the LKE cluster and details of the resources created by the Helm chart.

    Remember to replace the version and repo values in the helloworldChart declaration with the actual version number and Helm repository URL that hosts the Istio helloworld chart.

    After writing this program, you would typically run pulumi up to execute it with Pulumi. This will provision the cluster and deploy the Helm chart as described in the code.
