1. Deploy the fastly-exporter helm chart on Kubernetes

    TypeScript

    To deploy the fastly-exporter Helm chart on a Kubernetes cluster using Pulumi, you'll need to follow these steps:

    1. Have access to a Kubernetes cluster: Before you begin, make sure you have a Kubernetes cluster running and that you have kubectl installed and configured to interact with that cluster.

    2. Include required Pulumi packages: Ensure that the @pulumi/kubernetes package is included in your project's dependencies, as this package allows you to work with Kubernetes resources within Pulumi.

    3. Utilize the Helm Chart resource: You can use the kubernetes.helm.v3.Chart resource from the @pulumi/kubernetes package to deploy Helm charts. This resource represents a Helm chart in a Pulumi program.

    Here’s a Pulumi program written in TypeScript that shows how to deploy a Helm chart to your Kubernetes cluster.

    import * as k8s from "@pulumi/kubernetes"; const fastlyExporterChart = new k8s.helm.v3.Chart("fastly-exporter", { chart: "fastly-exporter", // Specify the Helm chart repository here, if it is not part of the stable repository. // repo: "https://my-helm-charts.example.com/", version: "0.1.0", // Specify the exact chart version you want to deploy. // You may also pass additional values to configure the Helm chart as needed. values: { // Provide configuration values for the fastly-exporter chart here. // Example: // serviceMonitor: { // enabled: true, // }, }, // Namespace where the Helm chart will be installed namespace: "default", // Change this if you wish to install the chart in a different namespace. }); // Optional: Export the public IP to access fastly-exporter if it creates an external endpoint. export const fastlyExporterIP = fastlyExporterChart.getResourceProperty("v1/Service", "fastly-exporter", "status").apply(status => status.loadBalancer.ingress[0].ip);

    This program defines a new fastly-exporter Helm chart and attempts to deploy it to a Kubernetes cluster. It assumes that you have the fastly-exporter chart available in your Helm chart repository. If your chart is hosted in a private or custom Helm chart repository, you will have to include the repo field with the URL of the repository.

    Key points to note:

    • The chart field specifies the name of the Helm chart. Here, it is "fastly-exporter".
    • The version field allows you to specify the version of the Helm chart you want to use. Replace "0.1.0" with the actual version of the fastly-exporter chart you want to deploy.
    • The values field allows you to specify configuration options for the chart. This is equivalent to customization you might perform using command-line arguments with Helm or a values.yaml file.

    Finally, if the Helm chart exposes an external endpoint through a Kubernetes Service of type LoadBalancer, I included an optional export of the resulting IP address, named fastlyExporterIP, which allows you to determine the IP address assigned by the load balancer.

    Before you run the Pulumi program, make sure to install the required Pulumi command-line tools and TypeScript dependencies using npm or yarn.

    To deploy this code:

    1. Ensure you have an active directory with a Pulumi project set up.
    2. Save this code in an index.ts file (the main file in a TypeScript Pulumi project).
    3. Ensure you have the Kubernetes provider configured either through a kubeconfig file or Pulumi configuration.
    4. Use the Pulumi CLI to run pulumi up, which will prompt you for confirmation before deploying the Helm chart to your cluster.

    Remember to replace placeholder values with actuals as per your requirements.
