1. Deploy the oidc-proxy helm chart on Azure Kubernetes Service (AKS)


    To deploy the oidc-proxy Helm chart on Azure Kubernetes Service (AKS) using Pulumi, you need to:

    1. Set up an AKS cluster: Before you can deploy the Helm chart, you need a working AKS cluster.
    2. Deploy the Helm chart: Once you have the Kubernetes cluster, you can proceed to define and deploy your Helm chart.

    Below is a program that demonstrates how to accomplish this with Pulumi. The program uses the @pulumi/azure-native and @pulumi/kubernetes packages to create these resources on Azure.

    First, we'll create an AKS cluster. For this example, we're assuming you have already configured your Azure credentials for Pulumi to use.

    We will define our AKS cluster with a predefined node count and size, as well as some other essential properties like the resource group. Please note that for managed clusters in Azure, Pulumi will automatically handle the creation of necessary services like ServicePrincipal and RoleAssignment.

    Then, we'll configure the Helm chart for oidc-proxy with any set of values you require. For brevity, I'll use an imaginary Helm repository and chart, which you should replace with the actual location and chart name of oidc-proxy.

    Here's the complete program:

    import * as pulumi from "@pulumi/pulumi"; import * as azure_native from "@pulumi/azure-native"; import * as k8s from "@pulumi/kubernetes"; // Create an Azure Resource Group const resourceGroup = new azure_native.resources.ResourceGroup("my-aks-resource-group"); // Create an AKS cluster const aksCluster = new azure_native.containerservice.ManagedCluster("my-aks-cluster", { // Define properties for the AKS cluster resourceGroupName: resourceGroup.name, agentPoolProfiles: [{ count: 2, // Number of nodes vmSize: azure_native.containerservice.ContainerServiceVMSizeTypes.Standard_DS2_v2, // Size of nodes mode: "System", // Mode of an agent pool (System or User) name: "agentpool" // Name of the agent pool }], dnsPrefix: "aks-cluster", // Prefix for the DNS name of the AKS cluster kubernetesVersion: "1.21.1", // Version of Kubernetes to use }, { parent: resourceGroup }); // Export the Kubeconfig for the AKS cluster export const kubeconfig = aksCluster.kubeConfig.apply(config => config.raw); // Create a Kubernetes provider instance that uses our AKS cluster from above const k8sProvider = new k8s.Provider("k8s-provider", { kubeconfig: kubeconfig, }); // Deploy the oidc-proxy Helm chart const oidcProxyChart = new k8s.helm.v3.Chart("oidc-proxy-chart", { chart: "oidc-proxy", version: "1.2.3", // Replace with the correct chart version fetchOpts: { // Replace with the actual repository that hosts the oidc-proxy Helm chart repo: "http://myhelmrepo.com/charts", }, namespace: "default", // Kubernetes namespace to deploy into // You can define additional customization for the Helm chart by specifying values values: { // Custom values go here. }, }, { provider: k8sProvider }); // Output the public IP of the oidc-proxy service, assuming it's a LoadBalancer service export const oidcProxyPublicIp = oidcProxyChart.getResourceProperty("v1/Service", "oidc-proxy", "status") .apply(status => status.loadBalancer.ingress[0].ip);

    Resource Descriptions:

    • ResourceGroup: The Azure resource group is a container that holds related resources for an Azure solution.
    • ManagedCluster: This represents an AKS cluster in Azure. We define properties like node count, size, DNS prefix, and the Kubernetes version to use.
    • Provider: A Pulumi Kubernetes provider is used to connect to the AKS cluster using its kubeconfig once it has been created. This provider will manage the Kubernetes resources.
    • Chart: A Helm chart is a collection of pre-configured Kubernetes resources. In this case oidc-proxy-chart is referenced, which should be replaced with the actual Helm chart name and repository.

    You can run this Pulumi program in your Pulumi project directory. Pulumi will first create the AKS cluster and, once it's ready, will deploy the oidc-proxy Helm chart to it. Lastly, the code exports the public IP address of the oidc-proxy, assuming it creates a service of type LoadBalancer.

    Make sure to replace the oidc-proxy Helm chart placeholder with the actual chart information before running this code. If you need to specify additional settings for the AKS cluster or the Helm chart, you can do so in the respective resource definitions.
