1. Deploy the kong-authorizer helm chart on Linode Kubernetes Engine


    To deploy the Kong Authorizer Helm chart on Linode Kubernetes Engine using Pulumi, you will typically follow these steps:

    1. Set up Pulumi to work with Linode Kubernetes Engine (LKE): This involves configuring authentication, usually via environment variables or a configuration file, so Pulumi can communicate with Linode's API.
    2. Create a Kubernetes cluster with Linode: Define a Kubernetes cluster resource using Pulumi's Linode provider, specifying the desired configuration for your cluster.
    3. Install the Helm Chart: Use the Helm provider in Pulumi to install the Kong Authorizer Helm chart into your Linode Kubernetes cluster.

    Now, let's go through the sample program. This TypeScript program illustrates how to deploy a Linode Kubernetes cluster and then install a Helm chart on it. I will include comments to explain each step.

    import * as linode from "@pulumi/linode"; import * as kubernetes from "@pulumi/kubernetes"; // Step 1: Create a new Linode Kubernetes Engine cluster const cluster = new linode.LkeCluster("my-cluster", { k8sVersion: "1.21", // specify the version of Kubernetes region: "us-central", // set the region you want your cluster to be in nodePools: { count: 3, // adjust the node count according to your needs type: "g6-standard-2", // select the type of nodes in your pool }, }); // Step 2: Configure the Kubernetes provider to use the Kubeconfig from the generated LKE cluster const provider = new kubernetes.Provider("my-provider", { kubeconfig: cluster.kubeconfigRaw, }); // Step 3: Install the Kong Authorizer helm chart onto your LKE cluster const kongAuthorizerRelease = new kubernetes.helm.v3.Chart("kong-authorizer", { // Define the Helm chart, version, and repository chart: "kong", // the name of the helm chart, ensure this corresponds to the Kong Authorizer chart version: "X.Y.Z", // replace with the specific version you want to deploy fetchOpts: { repo: "https://charts.konghq.com" } }, { provider: provider }); // Export the cluster's kubeconfig and the Helm release's name export const kubeconfig = cluster.kubeconfigRaw; export const kongReleaseName = kongAuthorizerRelease.name;

    Be sure to replace "X.Y.Z" with the actual version of the Kong Authorizer Helm chart you wish to deploy. The kubeconfig export will allow you to interact with your cluster using kubectl after deployment.

    To run this program, use the following steps:

    • Ensure that you have the Pulumi CLI installed and are logged in.
    • Ensure that you have set up Linode credentials correctly. Pulumi, by default, uses environment variables or configuration set via their CLI, for example, LINODE_TOKEN.
    • Create a new directory for your Pulumi program.
    • Initialize your Pulumi project with the respective commands such as pulumi new and select the applicable template for TypeScript.
    • Copy the code provided into a file named index.ts.
    • Modify package.json to include necessary Pulumi and provider packages.
    • Run npm install or yarn install to make sure all dependencies are installed.
    • Preview your changes with pulumi preview to see what actions Pulumi will take.
    • Deploy your changes with pulumi up.

    You now have a Helm chart deployed on an LKE cluster using Pulumi!
