1. Deploy the servicemesh-istio-resource helm chart on Kubernetes


    To deploy a Helm chart using Pulumi, you need to have Pulumi installed and configured with access to your Kubernetes cluster. Assuming you already have a Kubernetes cluster running and your kubectl configured to interact with it, we can proceed with deploying the Istio service mesh using Pulumi.

    We will be using the kubernetes.helm.v3.Chart resource from the Pulumi Kubernetes provider to deploy the Istio service mesh. The Chart resource is used to represent a Helm chart in a Pulumi program, allowing us to deploy applications described in Helm charts.

    Here's how you can do it:

    1. We'll reference the Chart resource from the @pulumi/kubernetes package, which enables us to deploy a Helm chart.
    2. We need to provide the chart name, servicemesh-istio, as per your request.
    3. We'll use the official Istio Helm repository, so we'll need to set the repo parameter accordingly.
    4. If we need to customize our Istio deployment, such as enabling or disabling specific features, we can pass these customizations using the values parameter.

    Below is a Pulumi TypeScript program that performs the deployment:

    import * as k8s from "@pulumi/kubernetes"; // Create an instance of the `kubernetes.helm.v3.Chart` resource to deploy Istio. // This will install the Istio service mesh into your Kubernetes cluster using the // specified Helm chart and version. const istioChart = new k8s.helm.v3.Chart("servicemesh-istio", { // Specify the Helm chart repository and name. chart: "istio", version: "1.12.1", // You can specify the version of the Helm chart you wish to deploy. fetchOpts:{ repo: "https://istio-release.storage.googleapis.com/charts", }, // Optionally, you can specify values to customize the Helm chart deployment. // This is akin to specifying `--set` flags in a `helm install` command, or // providing a custom `values.yaml` file. values: { // Customize values here. For example: // global: { // proxy: { // autoInject: "enabled", // }, // }, }, }, { // This is needed if you want to use a specific provider, omit if you are // using the default kubeconfig context or Pulumi provider configuration. provider: k8sProvider, }); // To see the public URL after deployment, we can export it: export const istioPublicUrl = istioChart.getResourceProperty("v1/Service", "istio-ingressgateway", "status");

    Please replace k8sProvider with your own Pulumi Kubernetes provider configuration if you are not using the default one.

    In the values field, you can customize the Istio installation according to your needs by providing overrides that are equivalent to what you might do with a values.yaml file in Helm. For example, enabling auto-injection of Istio sidecars, customizing resource requests and limits, enabling various Istio components, and more.

    Once you have this program ready, you can run it using the Pulumi CLI:

    • pulumi up to preview and deploy the changes.
    • pulumi stack output istioPublicUrl to get the output of the Istio public URL if available.

    This program assumes you have performed the necessary setup, such as installing Pulumi, configuring access to your Kubernetes cluster via kubeconfig, and setting up your Pulumi project and stack.

    Refer to the Chart resource documentation for more details on customization and configuration options.
