1. Deploy the helmchart helm chart on Kubernetes


    Deploying a Helm chart on a Kubernetes cluster involves several steps using Pulumi. First, you'll need a Kubernetes cluster running and accessible. For this example, we'll assume you have an existing cluster and you're using a Helm chart that's available in a public repository.

    We'll use Pulumi's Kubernetes provider to deploy a Helm chart into a Kubernetes cluster. Specifically, we'll use the helm.sh/v3.Chart resource from the Pulumi Kubernetes provider, which represents a Helm chart in a way that Pulumi can manage.

    Here's how you can write a Pulumi program in TypeScript to achieve this:

    1. First, we will import the necessary Pulumi and Kubernetes packages.
    2. We will instantiate a Helm chart resource using the helm.sh/v3.Chart class.
    3. We need to specify the chart's repository, name, version, and any custom values that are required.

    Here's what the program looks like:

    import * as k8s from "@pulumi/kubernetes"; // Create a Helm chart resource. // This will install the specified Helm chart into the Kubernetes cluster configured in your Pulumi stack. const helmChart = new k8s.helm.v3.Chart("my-helm-chart", { // You can specify the repository where your Helm chart is located. // For official Helm charts hosted by Helm, you don't need to specify a repo here. repo: "my-repo", // Specify the name of the chart. chart: "my-chart", // Specify the chart version. version: "1.2.3", // If you have custom values.yaml file for your Helm chart, pass the configuration here. // Otherwise, you can leave this section out to use the default chart values. values: { key1: "value1", key2: "value2", }, // Specify the namespace where the chart should be installed. // If not specified, it will be installed in the default namespace. namespace: "my-namespace", }); // To get information about the deployed chart, you can export outputs. export const chartName = helmChart.metadata.name;

    In the example above, replace "my-repo", "my-chart", "1.2.3", and the values inside values with the appropriate information for the Helm chart you want to deploy. Additionally, replace "my-namespace" with the namespace where you want to deploy the chart, or omit the namespace property to use the default namespace.

    This Pulumi program will need to be executed with the Pulumi CLI and assumes that you have already configured it with access to your Kubernetes cluster. Once you run pulumi up, Pulumi will handle the deployment of the Helm chart into your Kubernetes cluster using the specified values.

    Don't forget to install Pulumi and configure your Kubernetes cluster correctly prior to running this code. For more details and additional examples, you can refer to the Pulumi Kubernetes documentation available at Pulumi Kubernetes provider documentation.
