1. Deploy the tyk-dashboard helm chart on Google Kubernetes Engine (GKE)


    To deploy the Tyk Dashboard Helm chart on Google Kubernetes Engine (GKE), you'll need to follow several steps, including setting up a GKE cluster, installing the Helm command line tool if you haven't already, and then using it to deploy the Tyk Dashboard.

    In this Pulumi program, we'll create a GKE cluster and use the Helm chart resource to deploy the Tyk Dashboard. Pulumi allows you to define infrastructure as code using general programming languages. In this case, we will use TypeScript, a superset of JavaScript, to define the desired state of our infrastructure, which Pulumi will then deploy to GCP.

    We will use the google-native.container/v1.Cluster resource to create a GKE cluster, and kubernetes.helm.sh/v3.Chart to deploy the Helm chart for the Tyk Dashboard. The google-native package allows us to interact with GCP resources using their native properties and options, while the kubernetes package provides support for managing Kubernetes resources, including Helm charts.

    Here is the Pulumi TypeScript program to deploy the Tyk Dashboard on GKE:

    import * as gcp from "@pulumi/gcp"; import * as k8s from "@pulumi/kubernetes"; import * as pulumi from "@pulumi/pulumi"; // Create a GKE cluster const cluster = new gcp.container.Cluster("tyk-dashboard-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; // Create a Kubernetes provider instance that uses our cluster from above. const k8sProvider = new k8s.Provider("k8s-provider", { kubeconfig: cluster.kubeConfigRaw, }); // Deploy the Tyk Dashboard Helm chart const tykDashboardChart = new k8s.helm.v3.Chart("tyk-dashboard", { chart: "tyk-dashboard", version: "<ENTER DESIRED VERSION>", // Specify the version you wish to use fetchOpts: { repo: "https://helm.tyk.io/public/helm/charts/", // The repository where Tyk Dashboard Helm chart is stored }, }, { provider: k8sProvider }); // Export the Helm chart resources export const resources = tykDashboardChart.resources;

    Let's break down the code:

    1. We start by importing the required Pulumi packages to manage resources on GCP and Kubernetes.

    2. We create a new GKE cluster using the gcp.container.Cluster resource. We specify the initialNodeCount and nodeConfig which includes the machine type and required OAuth scopes for the nodes.

    3. We export the name of the cluster as a stack output, which can be helpful for future referencing using Pulumi’s stack outputs.

    4. We create a Kubernetes provider instance that uses the kubeConfigRaw output from the GKE cluster to interact with our new Kubernetes cluster.

    5. We then declare a new k8s.helm.v3.Chart resource for the Tyk Dashboard Helm chart, specifying the chart name, version, and repository URL.

    6. Finally, we export the resources created by the Helm chart, allowing you to inspect the deployed resources using Pulumi's stack outputs.

    Before running this program, ensure you have the following:

    • Pulumi CLI installed and configured with access to your GCP account.
    • GCP project and credentials set up and configured in Pulumi.
    • Helm command-line tool installed if you need to customize the Helm chart values (not covered in this code).

    To deploy this Pulumi program, you would save the code to a file (e.g., index.ts), open your terminal in the directory containing the file, and run pulumi up. Pulumi would then perform the deployment, showing you a preview before it carries out any changes. After reviewing the preview, you can proceed with the deployment.

    This program requires you to specify the desired version of the Tyk Dashboard Helm chart. You can find the version numbers and additional configuration options on the Tyk Helm Chart documentation.

    Please review and adjust the Tyk Dashboard Helm chart values and version according to your requirements.
