1. Deploy the tyk-dev-portal helm chart on Azure Managed Openshift Service


    Deploying the Tyk Developer Portal using a Helm chart on an Azure Managed OpenShift Service involves several steps. First, you'll need to create an OpenShift Managed Cluster in Azure. Once you have your OpenShift cluster running, you'll then use Helm to deploy the Tyk Developer Portal to that cluster.

    Below is a Pulumi TypeScript program that sets up an OpenShift Managed Cluster and deploys the Tyk Developer Portal Helm chart to it. Let's walk through the code step by step:

    Step 1: Import necessary modules

    We'll start by importing the pulumi, azure-native, and kubernetes modules. These modules contain the classes and functions we'll need to create the cluster and deploy the chart.

    Step 2: Create an OpenShift Managed Cluster

    We'll use the azure-native.containerservice.OpenShiftManagedCluster class to create a new managed OpenShift cluster. The parameters will include the location, resource group name, and other cluster-specific settings like the OpenShift version and the authentication profile.

    Step 3: Deploy the Helm Chart to the Cluster

    With the Kubernetes module, specifically the kubernetes.helm.v3.Chart class, we can deploy the Tyk Developer Portal Helm chart. We'll pass in parameters like the chart name, repository (if it's not a stable chart and needs a specific repo URL), and any custom values you wish to set.

    Full Pulumi Program:

    import * as pulumi from "@pulumi/pulumi"; import * as aks from "azure-native/containerservice"; import * as k8s from "@pulumi/kubernetes"; // Step 1: Create an Azure Managed OpenShift Cluster const clusterName = "openshift-cluster"; // Define the name of the cluster const location = "eastus"; // Define the location for the cluster const resourceGroupName = "myResourceGroup"; // Define the resource group name where the cluster will be created // Define the OpenShift Managed Cluster const cluster = new aks.OpenShiftManagedCluster(clusterName, { // Define location and resource group for the cluster location: location, resourceGroupName: resourceGroupName, // Define OpenShift version and authentication profile as required openShiftVersion: "3.11", authProfile: { identityProviders: [{ name: "Azure AD", provider: { kind: "AzureADIdentityProvider", clientId: "your-aad-client-id", // Replace with your actual client ID secret: "your-aad-secret", // Replace with your actual secret tenantId: "your-aad-tenant-id", // Replace with your actual tenant ID } }] }, // Define networking, master pool profile, and agent pool profiles as required }); // Step 2: Deploy the Tyk Developer Portal Helm Chart on the Openshift cluster const chartName = "tyk-dev-portal"; const chartVersion = "x.y.z"; // Replace with the actual chart version const helmChart = new k8s.helm.v3.Chart(chartName, { chart: chartName, version: chartVersion, fetchOpts: { repo: "https://helm.repo.address", // Replace with the actual Helm chart repo address, if needed } // Include additional Helm chart values or configuration options as required // values: { ... } }, { provider: cluster }); // Export the cluster's kubeconfig export const kubeConfig = cluster.kubeConfigRaw;

    Explanation of the Program

    • The aks.OpenShiftManagedCluster class is used to create an Azure Managed OpenShift Service. The cluster creation parameters, including the OpenShift version and the Azure AD credentials, are specified within this class.
    • The k8s.helm.v3.Chart class is used to deploy Helm charts to a Kubernetes cluster. We reference the Tyk Developer Portal Helm chart by its name and optionally specify a version and repository.
    • The cluster object is used as a provider for the Helm chart deployment to ensure that the Helm chart is deployed to the newly created OpenShift cluster.
    • The kubeConfig is exported to facilitate interaction with the cluster using kubectl once it's set up.

    What's Next?

    Once the Pulumi program runs, it will:

    • Set up an Azure Managed OpenShift Service.
    • Deploy the Tyk Developer Portal Helm chart to the created OpenShift Service.

    To run this Pulumi program, replace placeholders like your-aad-client-id, your-aad-secret, your-aad-tenant-id, x.y.z, and https://helm.repo.address with actual values relevant to your use case, and then use the following commands:

    1. Install the Pulumi CLI and log in.
    2. Create a new directory for your project and initialize a new Pulumi project using pulumi new azure-typescript.
    3. Replace the content of index.ts with the program above.
    4. Run pulumi up to preview and deploy the changes.

    Remember, you'll need to have Azure credentials configured on the machine running Pulumi. The Pulumi CLI will use these credentials to authenticate with Azure and create the resources.
