1. Deploy the ebpf-exporter helm chart on Google Kubernetes Engine (GKE)


    To deploy the ebpf-exporter Helm chart on Google Kubernetes Engine (GKE) using Pulumi, you will need to perform a few key steps:

    1. Set up a GKE cluster.
    2. Configure Pulumi to use the Helm package.
    3. Deploy the ebpf-exporter Helm chart to the GKE cluster.

    Below is a Pulumi program in TypeScript that demonstrates how to accomplish this. It assumes that you have already set up and authenticated the Pulumi CLI with appropriate GCP credentials. Moreover, it assumes you have the pulumi and @pulumi/gcp NPM packages installed.

    Firstly, we set up a GKE cluster by creating an instance of gcp.container.Cluster. Next, we use @pulumi/kubernetes to interact with the Kubernetes API, including deploying Helm charts.

    Here's the full program:

    import * as pulumi from "@pulumi/pulumi"; import * as gcp from "@pulumi/gcp"; import * as k8s from "@pulumi/kubernetes"; // Create a GKE cluster. const cluster = new gcp.container.Cluster("ebpf-exporter-cluster", { initialNodeCount: 2, nodeConfig: { machineType: "n1-standard-1", oauthScopes: [ "https://www.googleapis.com/auth/compute", "https://www.googleapis.com/auth/devstorage.read_only", "https://www.googleapis.com/auth/logging.write", "https://www.googleapis.com/auth/monitoring", ], }, }); // Export the Cluster name export const clusterName = cluster.name; // Export the Kubeconfig to access the GKE cluster with kubectl. export const kubeconfig = pulumi. all([cluster.name, cluster.endpoint, cluster.masterAuth]). apply(([name, endpoint, masterAuth]) => { const context = `${gcp.config.project}_${gcp.config.zone}_${name}`; return `apiVersion: v1 clusters: - cluster: certificate-authority-data: ${masterAuth.clusterCaCertificate} server: https://${endpoint} name: ${context} contexts: - context: cluster: ${context} user: ${context} name: ${context} current-context: ${context} kind: Config preferences: {} users: - name: ${context} user: auth-provider: config: cmd-args: config config-helper --format=json cmd-path: gcloud expiry-key: '{.credential.token_expiry}' token-key: '{.credential.access_token}' name: gcp `; }); // Create a Kubernetes provider instance that uses our cluster from above. const clusterProvider = new k8s.Provider("gkeK8s", { kubeconfig: kubeconfig, }); // Deploy the ebpf-exporter Helm chart into the GKE cluster. const ebpfExporterChart = new k8s.helm.v3.Chart("ebpf-exporter", { chart: "ebpf-exporter", version: "YOUR-CHART-VERSION", // specify the version of the chart fetchOpts:{ repo: "https://YOUR_HELM_CHART_REPOSITORY", // specify the Helm chart repository }, }, { provider: clusterProvider }); // Export the ebpf-exporter Helm chart deployment's status. export const ebpfExporterStatus = ebpfExporterChart.status;

    In this program:

    • We create a GKE cluster with basic settings: 2 nodes of type n1-standard-1. Adjust the size and type of the node pool to suit your workload and budget. The OAuth scopes provided are standard for GKE and give the nodes access to other Google Cloud services.

    • The kubeconfig is generated so you can use it with kubectl if you need to interact with your GKE cluster directly.

    • We instantiate a Kubernetes provider pointing to our newly created GKE cluster. We use this provider when deploying the ebpf-exporter chart to ensure the chart is installed into the right cluster.

    • Next, we deploy the ebpf-exporter Helm chart, specifying the chart's version and the repository where it's located. Please replace YOUR-CHART-VERSION with the version of the ebpf-exporter chart you want to install and https://YOUR_HELM_CHART_REPOSITORY with the URL to the chart's repository.

    Make sure to replace placeholders such as YOUR-CHART-VERSION and https://YOUR_HELM_CHART_REPOSITORY with actual values based on the chart you wish to deploy. The versions and URL can change over time, so it's crucial to refer to the official ebpf-exporter Helm chart documentation for the correct details.

    After the Pulumi program is ready, deploy it via the Pulumi CLI:

    pulumi up

    This will provision the GKE cluster and deploy the ebpf-exporter Helm chart as specified in your program, enabling you to use eBPF for observability functions on your Kubernetes cluster.
