1. Deploy the mod-data-import-converter-storage helm chart on Kubernetes


    To deploy a Helm chart on a Kubernetes cluster using Pulumi, we will use the @pulumi/kubernetes library. This library allows us to manage Kubernetes resources, including deploying Helm charts, through Pulumi's infrastructure-as-code approach.

    Below, I'll walk you through the process of deploying the "mod-data-import-converter-storage" Helm chart. This example assumes that you have a Kubernetes cluster up and running, and that you have configured your Pulumi environment to communicate with your Kubernetes cluster.

    First, we'll need to import necessary Pulumi packages for TypeScript and then instantiate a Pulumi Kubernetes chart resource. We will use the kubernetes.helm.v3.Chart resource to deploy the Helm chart. The Helm chart's repo, name, and optionally version properties must be specified to indicate which chart to deploy.

    The values property is an object representing any custom value overrides for the Helm chart, and the namespace property specifies the Kubernetes namespace to deploy the chart to. If the namespace doesn't exist, it will be created.

    Let's now look at the Pulumi program in TypeScript:

    import * as pulumi from "@pulumi/pulumi"; import * as k8s from "@pulumi/kubernetes"; // Define the settings for the Helm chart we want to deploy. const chartName = "mod-data-import-converter-storage"; const chartVersion = "x.y.z"; // Specify the exact chart version you want to deploy const chartNamespace = "default"; // Define the namespace where the chart will be installed. const helmChart = new k8s.helm.v3.Chart(chartName, { chart: chartName, version: chartVersion, namespace: chartNamespace, // If Helm chart values are to be customized, provide them as an object. // values: { /* custom values */ } // E.g., to set a custom value "replicaCount" for the chart // values: { // replicaCount: 2, // }, // In case your chart needs a specific repository to be added, you can specify it below: // fetchOpts: { // repo: "http://example.com/helm/charts", // }, }); // Export the deployment name export const deploymentName = helmChart.getResourceProperty("v1/Service", chartName, "metadata").apply(m => m.name);

    In this code:

    • We import the Pulumi Kubernetes package.
    • We create a new Helm chart instance using k8s.helm.v3.Chart and provide it with the required properties such as the chart name, version, and namespace.
    • If you need to override chart values, uncomment the values section and configure as needed.
    • If your chart is in a custom Helm repository, you would need to specify the repo URL within fetchOpts.
    • Finally, we export the name of the deployment which could be useful if you want to reference the deployment later on.

    When running this Pulumi program, Pulumi will perform the following actions:

    1. It will connect to your Kubernetes cluster using your current context set in ~/.kube/config or the one configured in your Pulumi stack.
    2. It will ensure that the specified Helm chart is deployed to the cluster in the given namespace with any custom values you may have provided.

    To apply the above Pulumi program:

    1. Save the code into a file with a .ts extension, for example, index.ts.
    2. Initialize a new Pulumi project with pulumi new if you haven't done so.
    3. Run pulumi up to deploy your Helm chart to Kubernetes.

    Pulumi will execute the deployment and output any resources it created or modified. Remember that you'll also need the Helm CLI and Kubernetes CLI installed and configured to work with your specific environments.
