1. Deploy the pgbench helm chart on Linode Kubernetes Engine


    To deploy the pgbench Helm chart on Linode Kubernetes Engine (LKE) using Pulumi, you will follow a few high-level steps:

    1. Set up a Kubernetes cluster on Linode: If you don't have an existing LKE cluster, you'll need to create one. Pulumi can provision a new LKE cluster using the linode provider.

    2. Install the Helm chart: You can deploy Helm charts into the LKE cluster using the kubernetes provider in Pulumi.

    Below is a Pulumi program written in TypeScript that demonstrates these steps. The program assumes that you have already configured your Pulumi CLI with the necessary Linode credentials.

    This Pulumi program will:

    • Create a new Linode Kubernetes Engine cluster if one does not already exist.
    • Deploy the pgbench Helm chart into the LKE cluster.

    Make sure you have the Pulumi CLI installed and set up with the Linode provider and the Kubernetes provider before running this program.

    import * as pulumi from "@pulumi/pulumi"; import * as linode from "@pulumi/linode"; import * as k8s from "@pulumi/kubernetes"; // Create a Linode Kubernetes Engine Cluster. const cluster = new linode.LkeCluster("my-cluster", { label: "my-lke-cluster", k8sVersion: "1.23", region: "us-central", nodePools: [{ type: "g6-standard-2", count: 1, }], }); // Export the kubeconfig of the cluster. export const kubeconfig = cluster.kubeconfig; // Set up a Kubernetes provider using the kubeconfig. const k8sProvider = new k8s.Provider("k8s-provider", { kubeconfig: cluster.kubeconfig, }); // Deploy the 'pgbench' Helm chart into the Kubernetes cluster using the Helm Chart resource. const pgbenchChart = new k8s.helm.v3.Chart("pgbench-chart", { // Replace with the correct repository and chart details if 'pgbench' is not the actual chart name. // Alternatively, if you have the chart already downloaded, you can set the `path` property, // and Pulumi will use the local chart. chart: "pgbench", version: "1.0.0", // Specify the version of the chart you want to deploy. fetchOpts: { repo: "http://charts.example.com/", // Replace with the correct Helm chart repository. }, }, { provider: k8sProvider }); // Optional: Expose cluster services using Pulumi outputs. export const pgbenchService = pgbenchChart.getResource("v1/Service", "pgbench");


    • Configure linode.LkeCluster with appropriate attributes for your project. You may need to change the k8sVersion to match an available version in your region, adjust the region, and the nodePools configuration as needed for your use case.
    • In the k8s.helm.v3.Chart resource, replace the chart, version, and fetchOpts.repo with the actual values for the pgbench Helm chart. If you have the pgbench chart hosted in a repository, specify the repository's URL. If you have the chart locally, you can use the path attribute to specify the directory path to the chart instead.
    • The kubeconfig generated by creating the Linode cluster is used to configure the Kubernetes provider.
    • Exporting resources like pgbenchService is useful if you want to capture the deployed Helm chart's Kubernetes resources and expose details about the service, such as endpoints or ports. You can access these outputs with the pulumi stack output command after deployment.
