1. Deploy the library-chart helm chart on Kubernetes


    To deploy a Helm chart on Kubernetes using Pulumi, you'll be using the @pulumi/kubernetes package, which allows you to manage Kubernetes resources with Pulumi programs. The specific resource we will use for deploying a Helm chart is Chart from the helm.sh/v3 API.

    Before you start writing the Pulumi program, make sure you have the following prerequisites in place:

    1. Pulumi CLI installed.
    2. Configured Kubernetes cluster and kubectl configured to talk to your cluster. Pulumi will use the same configuration as kubectl to interact with your Kubernetes cluster.
    3. Node.js and npm installed.

    Let's break down the steps that you'll need to follow:

    1. Import necessary libraries: Begin by importing the @pulumi/kubernetes library.
    2. Create a Kubernetes Chart: Use the Chart resource to deploy the helm chart to your Kubernetes cluster. You'll need to specify the chart name, and optionally its version, repository, and any custom values you want to override in the chart's default configuration.

    Here's a Pulumi program written in TypeScript that deploys the "library-chart" Helm chart on Kubernetes:

    import * as k8s from "@pulumi/kubernetes"; // Create a Kubernetes Chart resource using a Helm chart from a repository. const chart = new k8s.helm.v3.Chart("library-chart", { // Replace 'chart-name' with the actual name of the chart you want to deploy. // The chart can be from any reachable Helm chart repository. chart: "chart-name", // Optionally: Specify the Helm chart version you want to deploy. version: "version-number", // If the Helm chart is in a custom repository (not stable), specify it here. // e.g., https://charts.your-company.com/ fetchOpts: { repo: "https://charts.your-company.com/", }, // Optionally: Provide custom values to configure the Helm chart. // Values here will override the default values in the Helm chart. values: { // Custom values set here will be specific to the chart. // For example, if the 'library-chart' accepts 'serviceType', it can be set like this: serviceType: "ClusterIP", }, }); // Export the chart's name and status. export const chartName = chart.metadata.apply(m => m.name); export const chartStatus = chart.status.apply(s => s);

    In this program, you begin with importing the @pulumi/kubernetes package. You then use the Chart class to create a new Helm chart resource that Pulumi will manage. Replace "chart-name" with the name of the Helm chart you want to deploy, and specify the "version-number" if you have a specific version you wish to use. In the fetchOpts property, you provide the URL to the Helm repository if the chart isn't located in the default Helm repository.

    Lastly, we have the values field where you can override or provide any values that the Helm chart accepts. For customizing your deployment, refer to the specific Helm chart documentation for what values are available to set.

    When you run this Pulumi program, Pulumi will install the Helm chart specified on your currently configured Kubernetes cluster.
