1. Deploy the tyk-data-plane helm chart on Linode Kubernetes Engine

    TypeScript

    Deploying a Helm chart on Linode Kubernetes Engine (LKE) using Pulumi is accomplished by performing several steps:

    1. Set up Pulumi to manage Linode resources.
    2. Create a Kubernetes cluster on LKE.
    3. Deploy the Helm chart onto the Kubernetes cluster.

    Below, I'll guide you through setting up Pulumi with Linode, creating a Kubernetes cluster using Pulumi's Linode provider, and then deploying the tyk-data-plane Helm chart on that cluster. We will use the @pulumi/kubernetes package to manage Helm charts.

    Before you start, make sure you have installed Pulumi and set up your Linode access token as mentioned in Pulumi's Linode documentation.

    Now, let's proceed with the Pulumi program in TypeScript:

    import * as pulumi from "@pulumi/pulumi"; import * as linode from "@pulumi/linode"; import * as k8s from "@pulumi/kubernetes"; // Create a new Linode Kubernetes cluster. const cluster = new linode.LkeCluster("tyk-cluster", { label: "tyk-data-plane-cluster", k8sVersion: "1.20", // Specify the Kubernetes version (ensure it's supported on Linode LKE) region: "us-central", // Specify the region where you want to deploy the cluster nodePools: [{ type: "g6-standard-1", count: 3, // Adjust the node count as per your requirements }], }); // Create a new Kubernetes provider instance using the kubeconfig from generated Linode Kubernetes cluster const k8sProvider = new k8s.Provider("lke-k8s-provider", { kubeconfig: cluster.kubeconfig, }); // Deploy the `tyk-data-plane` Helm chart using the k8s provider const tykDataPlaneChart = new k8s.helm.v3.Chart("tyk-data-plane-chart", { chart: "tyk-headless", version: "0.7.0", // Use the appropriate chart version repo: "tyk-helm-chart", // The repository where the chart can be found. namespace: "tyk", // Define the namespace where the chart should be installed. fetchOpts: { repo: "https://helm.tyk.io/public/helm/charts/", // The actual repository URL }, }, { provider: k8sProvider }); // Export the Cluster's kubeconfig and the Helm chart deployment status export const kubeconfig = cluster.kubeconfig; export const tykDeploymentStatus = tykDataPlaneChart.status;

    Explanation:

    • The code uses the @pulumi/linode package to create an LKE cluster.
    • We specify the necessary details such as Kubernetes version, region, and the type and count of nodes within the linode.LkeCluster resource.
    • The @pulumi/kubernetes package is utilized to set up the Kubernetes provider with Linode's kubeconfig.
    • We deploy the tyk-data-plane Helm chart by creating an instance of k8s.helm.v3.Chart. Make sure to specify the correct version and repository details for the Helm chart you wish to deploy.
    • fetchOpts is where you put the actual URL to the Helm repository where the chart is located.
    • Two values are exported: the kubeconfig for accessing your LKE cluster and the deployment status which helps in understanding if the deployment went through successfully.

    Make sure to replace placeholders for chart version and other parameters with the actual values you want to use. You can typically find the available chart versions and other configuration options on the Helm chart's repository page or documentation.

    After running this Pulumi program, you'll have a Linode Kubernetes Engine cluster with the tyk-data-plane Helm chart deployed. You can manage your deployment and the resources through Pulumi for updates, rollbacks, or teardowns.
