1. Deploy the graphite-exporter helm chart on Kubernetes

    TypeScript

    To deploy the graphite-exporter Helm chart on Kubernetes using Pulumi, you will need to follow a few steps. Let’s break them down:

    1. Setting Up Your Kubernetes Cluster: You need to have a Kubernetes cluster up and running. You can create one using Pulumi with a provider like AWS EKS, Azure AKS, or Google GKE, or you can use an existing cluster.

    2. Configuring Pulumi to Access the Cluster: Make sure that Pulumi has access to your Kubernetes cluster. This can typically be done by pointing Pulumi to your kubeconfig file.

    3. Installing the Pulumi Kubernetes Provider: The Pulumi Kubernetes provider is used to interact with your Kubernetes cluster.

    4. Using the Helm Chart Resource: Pulumi's Kubernetes provider offers the Chart resource that allows you to deploy Helm charts.

    5. Deploying the graphite-exporter Chart: Specify the details of the graphite-exporter chart such as its version, any custom values it needs, and the namespace to deploy it in.

    Here’s a complete Pulumi program in TypeScript that deploys the graphite-exporter Helm chart on a pre-existing Kubernetes cluster:

    import * as k8s from '@pulumi/kubernetes'; // Helm chart version to install const chartVersion = "0.1.0"; // Use the preferred chart version // Configuration for the graphite-exporter Helm chart const graphiteExporterChart = new k8s.helm.v3.Chart("graphite-exporter", { chart: "graphite-exporter", version: chartVersion, fetchOpts: { repo: "https://helm.repository.url", // Replace with the actual chart repository URL }, // Specify the namespace to install to namespace: "default", // Change to the desired namespace // You can pass additional configuration values to the Helm chart values: { // Examples of typical configuration variables service: { servicePort: 80, }, // If the chart requires more custom values, include them here }, }); // Export the URL for the graphite-exporter so that you can access it from outside export const graphiteExporterURL = graphiteExporterChart.getResourceProperty( "v1/Service", // Assuming the Helm chart creates a Service "graphite-exporter", // The name might be different depending on the chart's default naming "status", ).apply(status => `http://${status.loadBalancer.ingress[0].hostname}`);

    Important Notes:

    • Replace "https://helm.repository.url" with the actual Helm chart repository where the graphite-exporter chart is hosted.
    • The values field in the Chart resource is where you can specify customization options for the graphite-exporter. The exact variables will depend on the chart's values.yaml file.

    This program defines a single Helm chart resource called graphite-exporter. The k8s.helm.v3.Chart resource is part of the Pulumi Kubernetes SDK and represents a Helm chart. The configuration options passed in the values field allow you to modify the default behavior of the chart, as you might similarly do with helm install or helm upgrade commands.

    Once deployed, the graphiteExporterURL resource property allows you to programmatically get the URL to access the graphite-exporter, assuming the chart exposes it via a Kubernetes Service with LoadBalancer.

    To run this Pulumi program:

    • Install Pulumi CLI and set up the required dependencies.
    • Have Node.js and NPM installed to handle the TypeScript Pulumi program.
    • Make sure you are authenticated to the Kubernetes cluster and that your kubeconfig is correctly set up.

    After running this program with Pulumi (pulumi up), the specified version of the graphite-exporter Helm chart will be deployed to your Kubernetes cluster.
