1. Deploy the kube-oidc-proxy helm chart on Azure Managed Openshift Service


    To deploy the kube-oidc-proxy Helm chart on an Azure Managed OpenShift Service, you'll need to complete several steps:

    1. Set up an Azure Managed OpenShift Service.
    2. Install Helm and configure it to work with your Kubernetes cluster.
    3. Deploy the kube-oidc-proxy helm chart to your Azure Managed OpenShift Service.

    Below, I will guide you through the Pulumi program written in TypeScript that accomplishes these steps.

    Setting up Azure Managed OpenShift Service

    We will start by setting up an Azure Managed OpenShift Cluster using the azure-native.containerservice.OpenShiftManagedCluster resource.

    This resource will create an OpenShift cluster with the specified configurations in your Azure account. You need to provide essential properties such as the location and the OpenShift version to use. You will also need to define the network profile and the profiles for master and agent nodes in the cluster, among other configurations.

    Installing Helm and Configuring Kubernetes

    After setting up the OpenShift cluster, we need to configure Pulumi to work with Kubernetes. Pulumi has built-in support for Helm charts with the kubernetes.helm.v3.Chart resource, allowing you to deploy Helm charts directly.

    Deploying kube-oidc-proxy Helm Chart

    Finally, you will use the kubernetes.helm.v3.Chart resource to deploy the kube-oidc-proxy Helm chart. This Helm chart will be configured to work with the Azure Managed OpenShift Service you set up in the first step.

    Here is the complete Pulumi program that performs the steps outlined above:

    import * as pulumi from "@pulumi/pulumi"; import * as containerservice from "@pulumi/azure-native/containerservice"; import * as k8s from "@pulumi/kubernetes"; // Step 1: Set up the Azure Managed OpenShift Service. const openShiftCluster = new containerservice.OpenShiftManagedCluster("myOpenShiftCluster", { // Update these values with your desired configuration. resourceGroupName: "myResourceGroup", resourceName: "myOpenShiftCluster", location: "East US", openShiftVersion: "3.11", // Specify the OpenShift version you want to use. // Define the network profile according to your requirements. networkProfile: { vnetCidr: "", }, // Agent pool profiles can be defined here to specify the size and number of VMs for your nodes. agentPoolProfiles: [{ name: "agentpool", count: 3, // Number of VMs to be used as worker nodes. vmSize: "Standard_D4s_v3", // Size of the VMs. role: "compute", osType: "Linux", }], // Master pool profile needs to be defined here as well. masterPoolProfile: { count: 3, // Number of VMs to be used as master nodes. vmSize: "Standard_D4s_v3", }, }); // Step 2: Set up a provider to interact with the newly-created OpenShift Cluster. const provider = new k8s.Provider("openshiftProvider", { kubeconfig: openShiftCluster.kubeconfig, }); // Step 3: Deploy the kube-oidc-proxy Helm Chart using the new Kubernetes Provider. const kubeOidcProxyChart = new k8s.helm.v3.Chart("kube-oidc-proxy", { chart: "kube-oidc-proxy", // Specify the repository that hosts the kube-oidc-proxy Helm chart. // If it's not available in the default helm repo. fetchOpts: { repo: "https://charts.jetstack.io", }, // You can include additional configuration here: values: { // Specify any specific values needed for the kube-oidc-proxy Helm chart. }, }, { provider }); // Export the kubeconfig to access the cluster. export const kubeConfig = openShiftCluster.kubeconfig;

    In the program above, first, we import the necessary Pulumi packages. Then, we define the Azure OpenShift Cluster, specifying configuration such as the version, network profile, agent pool profiles, and master pool profile. We also create a Kubernetes provider to interact with the OpenShift cluster.

    Lastly, we use the kubernetes.helm.v3.Chart resource to deploy the kube-oidc-proxy Helm chart from the specified Helm chart repository, utilizing the Kubernetes provider configured to manage the OpenShift cluster.

    Do note that to run this program, you need to have Pulumi installed and configured for use with Azure. You should also have the necessary Azure permissions to create resources in your Azure account.

    Remember to replace dummy values like myResourceGroup, myOpenShiftCluster, and any other configurations with the actual values that match your Azure environment and requirements.

    After deploying this program with Pulumi, your Azure Managed OpenShift Service will be configured with kube-oidc-proxy set up and running. Use the exported kubeconfig to interact with your cluster using the kubectl command-line tool.
