1. Deploy the restore helm chart on Kubernetes


    Deploying Helm charts on Kubernetes with Pulumi is done using the helm.sh/v3.Chart class from the @pulumi/kubernetes package. This class represents a Helm chart installation and it allows you to deploy applications packaged as Helm charts to a Kubernetes cluster.

    First, install the @pulumi/kubernetes package using npm if you have not already done so:

    npm install @pulumi/kubernetes

    In this program, I will show you how to create an instance of a Helm chart using Pulumi. I'll assume that you have a Kubernetes cluster already up and running, and your kubeconfig file is set up correctly to communicate with your Kubernetes cluster.

    Here's a detailed breakdown of how to deploy a Helm chart named "restore" with Pulumi:

    1. We'll import the necessary libraries from Pulumi and Kubernetes.
    2. We'll create a new chart using the Chart class, which will install the "restore" Helm chart to the Kubernetes cluster.
    3. For demonstration purposes, let's assume that the "restore" chart is available in a Helm repository. You must provide the correct repository URL.
    4. You will also see an optional values field where you can specify the chart's values that you want to override.

    Now, let's see the code example:

    import * as k8s from "@pulumi/kubernetes"; // Create a new Helm chart instance for the "restore" chart. const restoreChart = new k8s.helm.v3.Chart("restore", { // The Helm chart repository where your "restore" chart is located. repo: "my-helm-repo", // Replace with your Helm repository name. chart: "restore", // (Optional) Version of the chart to deploy. If not provided, the latest version will be deployed. version: "1.2.3", // Replace with the specific chart version you want to deploy. // (Optional) Set values for the chart. values: { // Key-value pairs matching the values.yaml file in the "restore" chart. setting1: "value1", setting2: "value2", // Add additional value overrides as needed for your chart. } }); // To interact with resources managed by the chart, you can export relevant endpoints or other data: export const chartName = restoreChart.getResourceProperty("v1/Service", "<service-name>", "metadata").name;

    In the above code:

    • Replace "my-helm-repo" with the actual name of your Helm repository.
    • Replace "1.2.3" with the actual version of the "restore" chart you want to deploy.
    • In the values section, replace setting1 and setting2 with the actual configuration parameters for your Helm chart. These values should correspond to the values you'd typically set in a values.yaml file or via --set when using the Helm CLI.

    Finally, to run the Pulumi program:

    1. Save the code into a TypeScript file, for example, index.ts.
    2. Run pulumi up in the terminal to execute the code.
    3. Pulumi will show a preview of the resources that will be created and ask for confirmation. If everything looks correct, proceed with the deployment.

    Remember to substitute all placeholders with the actual values that correspond to your Helm chart and environment. This approach will create and manage the Helm release as part of your Pulumi stack.
