1. Deploy the speedtest-tracker helm chart on Kubernetes

    TypeScript

    To deploy the speedtest-tracker Helm chart on Kubernetes using Pulumi, you'll be creating an instance of a Helm chart resource from the Kubernetes package. The helm.sh/v3.Chart resource allows you to deploy Helm charts into a Kubernetes cluster. Before you proceed with the Pulumi program, make sure you have the following prerequisites in place:

    1. A Kubernetes cluster where you have permission to deploy resources. You can use a local development cluster like minikube or Docker Kubernetes, or a cloud-based Kubernetes service.
    2. Pulumi CLI installed and configured for your Kubernetes cluster.
    3. Helm command-line tool installed, if you need to customize the Helm chart or inspect what's available in it.
    4. Node.js and npm installed, to run the TypeScript Pulumi program.

    Assuming you have your Kubernetes cluster configured and can access it using kubectl, you can now proceed with deploying the speedtest-tracker Helm chart.

    Below is a TypeScript Pulumi program that deploys the speedtest-tracker Helm chart. This program utilizes the @pulumi/kubernetes package to interact with the Kubernetes cluster and Helm charts.

    import * as k8s from "@pulumi/kubernetes"; // Define the settings for the speedtest-tracker Helm chart. const speedtestTrackerChart = new k8s.helm.v3.Chart("speedtest-tracker", { repo: "your-repo", chart: "speedtest-tracker", version: "desired-version", // Specify the version of the Helm chart if needed. namespace: "default", // Adjust the namespace according to your preference. // Values to override the default values in the Helm chart. values: { // For example, specify values that are specific to the speedtest-tracker chart. // service: { // type: "ClusterIP" // }, // You can set other values as needed based on your requirements. }, }); // Export the name of the chart deployed. export const chartName = speedtestTrackerChart.metadata.name;

    Here's what the program does:

    • We begin by importing the Kubernetes module from Pulumi's library.
    • We then create a new Helm chart resource using new k8s.helm.v3.Chart. This resource is responsible for fetching the Helm chart from a specified Helm repository and deploying it on the Kubernetes cluster associated with the current Pulumi context.
    • The repo property should be the name of the repo where the speedtest-tracker chart is hosted. This could be an official Helm repository or a custom one if the chart is not publicly available.
    • The chart property is set to "speedtest-tracker", which is the name of the Helm chart you want to deploy.
    • The version property allows you to specify a particular version of the Helm chart you wish to deploy. If omitted, the latest version will usually be deployed, but setting an exact version can ensure consistent deployments.
    • The namespace property lets you specify the Kubernetes namespace where the Helm chart will be deployed.
    • The values property is an object representing the configuration options for the Helm chart. You can override default values set in the Helm chart by specifying them here.

    To successfully deploy the speedtest-tracker Helm chart, make sure to replace "your-repo" with the actual repository name where the chart is hosted and "desired-version" with the specific chart version you want to use (if any).

    Finally, the program exports the name of the chart that was deployed, which can be useful if you need to reference the Helm deployment in subsequent Pulumi operations.

    After creating your Pulumi program, you can run the following commands to deploy your infrastructure:

    1. Initialize a new Pulumi project if you haven't already:

      pulumi new typescript

    2. Replace the content of index.ts with the program provided above and modify the configurations accordingly.

    3. Run npm install @pulumi/kubernetes to install the necessary Pulumi Kubernetes package.

    4. Deploy the resources using the pulumi up command. Pulumi will show what resources will be created before you confirm to proceed.

    Keep in mind to look up or configure the Helm repository that contains your speedtest-tracker chart. If it's publicly available, use the public repository URL; if it's private, ensure you have configured Helm to access the private repository, and the Kubernetes cluster has the necessary permissions to pull from that repository.
