1. Deploy the tm-forum-api helm chart on Kubernetes


    To deploy a Helm chart on Kubernetes using Pulumi, you need to set up your Kubernetes cluster (either locally like with Minikube or on a cloud provider), and then use the Pulumi Kubernetes provider to manage the deployment. The following program does just that by using the kubernetes.helm.v3.Chart resource.

    The kubernetes.helm.v3.Chart resource wraps the Helm chart and manages its deployment to a Kubernetes cluster. In this example, the tm-forum-api Helm chart is assumed to be available in a Helm repository that you can add to your Pulumi code.

    Below is a TypeScript program that uses Pulumi to deploy the tm-forum-api Helm chart to a Kubernetes cluster:

    import * as kubernetes from "@pulumi/kubernetes"; // You should have a Kubernetes cluster running and your `kubeconfig` file set up. // Create a Helm chart resource for the tm-forum-api application, assuming that this Helm chart // exists in the specified repository. const tmForumApiChart = new kubernetes.helm.v3.Chart("tm-forum-api", { // Replace with the correct repo URL. repo: "https://<helm-chart-repository>", chart: "tm-forum-api", // Specify the version of the chart if you want to pin to a specific version. // version: "1.0.0", // Values to pass to the Helm chart, this should be adjusted based on the tm-forum-api chart's configurable values. values: { // Example: If the chart allows you to configure a service type, you might specify a LoadBalancer for cloud environments. // service: { // type: "LoadBalancer", // }, }, // This assumes an existing namespace `tm-forum` has been created in Kubernetes. // You can also let Helm manage the namespace by using the setNamespace operation. namespace: "tm-forum", }, { // This is to ignore the resource awaiting til completion, this might be useful if you have post-install hooks that take a long time, etc. // skipAwait: false, }); // Export the base URL for the tm-forum-api. This assumes that the service is exposed via a LoadBalancer; otherwise, you might export a cluster IP or NodePort. export const tmForumApiBaseUrl = tmForumApiChart.getResourceProperty("v1/Service", "tm-forum-api", "status").apply(s => `http://${s.loadBalancer.ingress[0].hostname}`);

    In the above program, you'll need to replace the placeholder URL in repo: with the actual URL of the Helm repository where the tm-forum-api Helm chart is hosted.

    • The chart parameter specifies the name of the chart. In this case, it's tm-forum-api.
    • The version parameter can be used to pin the deployment to a specific version of the Helm chart. This is optional and can be omitted to always deploy the latest version.
    • The values object contains custom configuration values that are specific to the tm-forum-api chart. Check the Helm chart documentation for configurable options.
    • The namespace parameter specifies which namespace in the Kubernetes cluster to deploy the chart. This namespace should be created beforehand if not managed by Helm.
    • The export statement at the end of the program provides a way to extract the LoadBalancer’s hostname once the service is up and running, which you can then use to access your application.

    Run this Pulumi program with the Pulumi CLI by using the command pulumi up. This will deploy the tm-forum-api Helm chart to your Kubernetes cluster. If you have not set up a cluster or are unsure about how to configure kubeconfig, please consult the Kubernetes or cloud provider’s documentation on how to do that.
