1. Deploy the tyk-gateway helm chart on Azure Kubernetes Service (AKS)


    To deploy the Tyk Gateway helm chart on Azure Kubernetes Service (AKS), you will need to accomplish the following:

    1. Set up an AKS cluster on Azure.
    2. Install Pulumi's kubernetes and azure-native SDKs.
    3. Initialize Helm and install the Tyk Gateway Helm chart onto the AKS cluster.

    Below is a step-by-step guide to create a program that will deploy the Tyk Gateway on AKS using Pulumi with TypeScript.


    Before you begin, make sure you have the following prerequisites installed:

    Step 1: Create a new Pulumi project

    Start by creating a new Pulumi project. Run the following command and follow the prompts:

    pulumi new azure-typescript

    Step 2: Define AKS Cluster

    In your Pulumi program, you will define an AKS cluster using the azure-native package.

    Step 3: Define Helm Chart

    You will then declare the Tyk Gateway Helm chart using Pulumi's Kubernetes package.

    Now, let's write the code for these steps.

    import * as pulumi from "@pulumi/pulumi"; import * as azure from "@pulumi/azure-native"; import * as k8s from "@pulumi/kubernetes"; // Step 1: Create an AKS cluster // ResourceGroup is needed to group all the resources in Azure. const resourceGroup = new azure.resources.ResourceGroup("resourceGroup"); // Actual definition of the AKS cluster. const aksCluster = new azure.containerservice.ManagedCluster("aksCluster", { resourceGroupName: resourceGroup.name, agentPoolProfiles: [{ count: 1, vmSize: "Standard_DS2_v2", name: "agentpool", mode: "System", }], dnsPrefix: pulumi.interpolate`${pulumi.getStack()}-kube`, identity: { type: "SystemAssigned", }, }); // Step 2: Obtain the kubeconfig from the AKS cluster const creds = pulumi.all([resourceGroup.name, aksCluster.name]).apply(([rgName, clusterName]) => azure.containerservice.listManagedClusterUserCredentials({ resourceGroupName: rgName, resourceName: clusterName, }), ); const kubeconfig = creds.apply(creds => Buffer.from(creds.kubeconfigs[0].value, "base64").toString()); // Step 3: Initialize Kubernetes provider using obtained kubeconfig const k8sProvider = new k8s.Provider("k8sProvider", { kubeconfig: kubeconfig, }); // Step 4: Deploy the Tyk Gateway helm chart // Define the helm chart and the values const tykGatewayChart = new k8s.helm.v3.Chart("tyk-gateway", { chart: "tyk-headless", version: "1.9.1", fetchOpts:{ repo: "https://helm.tyk.io/public/helm/charts/", }, values: { // Define the necessary values here gateway: { // Example value, adjust as needed replicaCount: 1, }, }, }, { provider: k8sProvider }); // Export the kubeconfig to access the cluster with kubectl export const kubeConfig = kubeconfig;

    This Pulumi program performs several key actions:

    • It creates a new resource group in Azure to group the resources.
    • It sets up an AKS cluster with a single node in a pool.
    • It retrieves the kubeconfig file necessary to interact with the cluster.
    • It establishes a Pulumi Kubernetes provider with that kubeconfig.
    • It defines and installs the Tyk Gateway using its Helm chart.

    Next steps after running the program:

    To apply the Pulumi program, run pulumi up in your console. The Pulumi CLI will then preview the changes and ask for your confirmation to proceed with the deployment.

    Please note that you should consult the official Tyk Helm chart documentation for the specific values you might need to include in the values section of the Helm chart configuration. The example provided here is a basic setup, and for a production deployment, you might need to provide additional settings.
