1. Deploy the amazon-ec2-metadata-mock helm chart on Azure Managed Openshift Service

    TypeScript

    Deploying the amazon-ec2-metadata-mock Helm chart on Azure Managed OpenShift Service involves several steps. You will first need to create an OpenShift Managed Cluster in Azure using Pulumi, and then you will deploy the Helm chart to this cluster. Note that amazon-ec2-metadata-mock is typically used with Amazon EKS to simulate EC2 instance metadata for testing purposes, so using it on Azure Managed OpenShift is unconventional and may not work as expected due to differences in cloud environments.

    We'll start with a TypeScript program that leverages Pulumi's azure-native package to provision an Azure Red Hat OpenShift cluster. After creating the cluster, we will deploy the Helm chart using Pulumi's kubernetes package.

    Before diving into the code, let's outline the steps:

    1. Create an Azure Resource Group: A logical container that holds related resources for an Azure solution.

    2. Create an OpenShift Managed Cluster: An Azure service that allows you to deploy and manage OpenShift clusters.

    3. Set Up Kubeconfig: Adjust your kubeconfig to connect to the OpenShift cluster using the credentials obtained during cluster creation.

    4. Deploy the Helm Chart: Utilizing Pulumi's Kubernetes provider to deploy the amazon-ec2-metadata-mock Helm chart to your OpenShift cluster.

    Here's what the Pulumi program written in TypeScript might look like:

    import * as pulumi from "@pulumi/pulumi"; import * as azure from "@pulumi/azure-native"; import * as k8s from "@pulumi/kubernetes"; // Step 1: Create an Azure Resource Group const resourceGroup = new azure.resources.ResourceGroup("myResourceGroup"); // Step 2: Create an Azure Red Hat OpenShift cluster. const openshiftCluster = new azure.redhatopenshift.OpenShiftCluster("myOpenShiftCluster", { resourceGroupName: resourceGroup.name, resourceName: "myOpenShiftCluster", location: resourceGroup.location, clusterProfile: { pullSecret: "<pull secret>", // you will need to provide your Red Hat pull secret domain: "example.com", version: "4.3.0", // specify the version of OpenShift }, masterProfile: { vmSize: "Standard_D8s_v3", // specify the master VM size subnetId: "<subnet-id>", // provide a subnet ID within your Azure VNet where the master nodes will live }, workerProfiles: [{ name: "worker", vmSize: "Standard_D4s_v3", // specify the worker VM size count: 3, diskSizeGB: 128, subnetId: "<subnet-id>", // provide a subnet ID within your Azure VNet where the worker nodes will live }], servicePrincipalProfile: { clientId: "<app-id>", clientSecret: "<app-secret>", }, networkProfile: { podCidr: "10.128.0.0/14", serviceCidr: "172.30.0.0/16", }, }); // Step 3: Set up the Kubeconfig (handled automatically by Pulumi when using the Kubernetes provider) // After cluster creation, you can use the openshiftCluster.kubeconfig to configure kubectl. // Since Pulumi automatically uses this configuration when creating Kubernetes resources, you don't need to do this manually. // Step 4: Deploy the Helm Chart. We're still using the Helm chart even though it's designed for Amazon EKS // as the metadata mock service is not cloud specific, though some features may not work as they are AWS-specific. const helmChart = new k8s.helm.v3.Chart("amazon-ec2-metadata-mock", { chart: "amazon-ec2-metadata-mock", version: "0.1.2", // specify the exact chart version to use fetchOpts: { repo: "https://kubernetes-sigs.github.io/aws-ec2-metadata-mock/helm/", // URL of the helm chart repo }, namespace: "default", }, { provider: new k8s.Provider("k8s-provider", { kubeconfig: openshiftCluster.kubeconfig }) }); // Export the cluster's kubeconfig. export const kubeconfig = openshiftCluster.kubeconfig;

    This program sets up everything you need:

    • First, it creates a new resource group to hold the OpenShift cluster.
    • Next, it provisions the OpenShift cluster with a given domain, version, VM size, and subnet IDs. You will need to supply a Red Hat pull secret and details for your service principal.
    • Pulumi's Kubernetes provider automatically uses the kubeconfig provided by the OpenShift cluster to interact with it. There's no need for manual intervention here.
    • Finally, it uses the Kubernetes provider to deploy the Helm chart to the OpenShift cluster.

    Make sure you replace placeholder strings like <pull secret>, <subnet-id>, <app-id>, and <app-secret> with actual values for your Azure environment and Red Hat OpenShift subscription.

    You would run this program by installing the necessary Pulumi packages, setting up your cloud credentials, and running pulumi up to provision the resources. This would apply the configuration to your connected Azure cloud account, and if successful, the Kubernetes resources would be visible in your OpenShift cluster's default namespace.

    Keep in mind that deploying AWS-centric solutions to Azure might not provide the full feature set and could require additional configuration or alternatives that are more Azure-friendly.
