1. Deploy the tyk-gateway helm chart on Digital Ocean Kubernetes Service


    To deploy the tyk-gateway Helm chart on a Kubernetes cluster in DigitalOcean using Pulumi, you'll need to do the following:

    1. Provision a DigitalOcean Kubernetes (DOKS) cluster.
    2. Install the tyk-gateway Helm chart onto the cluster.

    Before you start, make sure you have the Pulumi CLI installed and configured with the necessary cloud provider credentials, in this case, DigitalOcean. You also need to have kubectl set up to interact with the cluster, as well as Helm if you need to customize the chart before deployment.

    First, the following TypeScript program will create a new DigitalOcean Kubernetes cluster. After the cluster is provisioned, you'll deploy the tyk-gateway Helm chart to the cluster. Each step is annotated with comments to help you understand the process:

    import * as digitalocean from "@pulumi/digitalocean"; import * as kubernetes from "@pulumi/kubernetes"; // Create a new DigitalOcean Kubernetes cluster. const cluster = new digitalocean.KubernetesCluster("do-cluster", { region: "nyc3", // Set the region to your preferred region. version: "latest", // Use the latest available version. nodePool: { name: "default-pool", // The name of the node pool. size: "s-2vcpu-2gb", // Choose the node size you want. nodeCount: 2, // Number of nodes in the node pool. }, }); // Once the cluster is created, configure Pulumi to use the cluster's kubeconfig. const kubeconfig = cluster.kubeConfigs[0].rawConfig; const provider = new kubernetes.Provider("do-k8s", { kubeconfig }); // Deploy the tyk-gateway Helm chart. const tykGatewayChart = new kubernetes.helm.v3.Chart("tyk-gateway", { chart: "tyk-gateway", // Name of the Helm chart. version: "1.0.0", // Specify the version of the chart, if necessary. namespace: "default", // The namespace into which to deploy. }, { provider }); // Export the cluster details. export const kubeconfigOutput = kubeconfig; export const clusterName = cluster.name; export const clusterEndpoint = cluster.endpoint;

    Here's a brief explanation of what each section of the program does:

    1. Import dependencies: Import the necessary Pulumi packages for DigitalOcean (@pulumi/digitalocean) and Kubernetes (@pulumi/kubernetes).

    2. Provision the DOKS cluster: An instance of KubernetesCluster is created in DigitalOcean. Replace the region, node size, and count with your preferences.

    3. Configure Pulumi with kubeconfig: Pulumi needs the kubeconfig file that DigitalOcean generates to interact with your Kubernetes cluster, which is retrieved from the cluster instance and used to instantiate the Kubernetes provider.

    4. Deploy the tyk-gateway Helm chart: The Chart resource from the @pulumi/kubernetes package is used to deploy the tyk-gateway Helm chart onto the cluster. You need to specify the chart name and optionally the version and namespace.

    5. Export cluster details: The program exports several details about the cluster such as the kubeconfig, the cluster name, and the endpoint to interact with the cluster.

    Make sure to replace "1.0.0" with the actual version of the tyk-gateway Helm chart that you wish to deploy. If you're unsure, you can find Helm chart versions on the Tyk official Helm chart repository.

    To run this program, make sure your Pulumi stack is properly set up and run pulumi up in your terminal. After confirming the preview, Pulumi will provision the cluster and deploy the Helm chart.

    Remember, since this example uses DigitalOcean, you must have the DigitalOcean provider set up in your Pulumi project and must have authenticated with DigitalOcean in your CLI environment.
