1. Deploy the openunison-k8s-login-activedirectory helm chart on Azure Kubernetes Service (AKS)


    To deploy the openunison-k8s-login-activedirectory Helm chart on Azure Kubernetes Service (AKS), you'll want to follow several steps. First, you will need to create an AKS cluster; then, you'll configure the Helm chart, preparing it for deployment.

    Below, I'll outline the necessary Pulumi program written in TypeScript to accomplish these tasks.

    Step 1: Setting up AKS Cluster

    Before deploying any Helm charts, an AKS cluster must be set up. You do this using azure-native.containerservice.ManagedCluster. This resource allows you to configure a managed Kubernetes cluster, specify the agent pool profiles, the network configuration, and the Kubernetes version.

    Step 2: Deploying the Helm Chart

    After your AKS cluster is up and running, you will deploy the Helm chart. For this, you can use kubernetes.helm.v3.Chart from Pulumi's Kubernetes provider. You'll need to provide the repository URL or the chart location, the name of the chart, the deployment values that will override any default configuration values, and the version of the chart if it's necessary.

    Here's a complete program that will create an AKS cluster and then deploy the openunison-k8s-login-activedirectory Helm chart to it.

    import * as pulumi from "@pulumi/pulumi"; import * as azure from "@pulumi/azure"; import * as azuread from "@pulumi/azuread"; import * as k8s from "@pulumi/kubernetes"; import * as azureNative from "@pulumi/azure-native"; const name = "openunison-aks"; // Create an Azure Resource Group const resourceGroup = new azure.core.ResourceGroup(name); // Create an AKS cluster const managedCluster = new azureNative.containerservice.ManagedCluster(name, { resourceGroupName: resourceGroup.name, agentPoolProfiles: [{ count: 2, maxPods: 110, mode: "System", name: "agentpool", osDiskSizeGB: 30, osType: "Linux", vmSize: "Standard_DS2_v2", }], dnsPrefix: name, // You need to setup this part with your own specific Azure AD details identity: { type: "SystemAssigned", }, kubernetesVersion: "1.20.9", location: resourceGroup.location, }); // Export the KubeConfig export const kubeConfig = pulumi.all([managedCluster.name, resourceGroup.name]).apply(([clusterName, rgName]) => { return azureNative.containerservice.listManagedClusterUserCredentials({ resourceGroupName: rgName, resourceName: clusterName, }); }).apply(creds => Buffer.from(creds.kubeconfigs[0].value, 'base64').toString()); // Create a Kubernetes provider instance that uses our cluster from above. const k8sProvider = new k8s.Provider("k8sProvider", { kubeconfig: kubeConfig, }); // Deploy the Helm chart for `openunison-k8s-login-activedirectory` const openunisonChart = new k8s.helm.v3.Chart("openunison-aks-ad", { repo: "tremolo", // This assumes there exists a helm repo named `tremolo` chart: "openunison-k8s-login-activedirectory", version: "x.y.z", // Replace with the correct chart version // Specify the values for your deployment as per the chart's documentation values: { // For example you'll specify your active directory details here as per your AD setup activeDirectory: { base: "dc=example,dc=com", // ... other related configuration }, // ... other related values }, }, { provider: k8sProvider }); // Export the public URL to access the OpenUnison portal export const openunisonUrl = openunisonChart.getResourceProperty("v1/Service", "<RELEASE-NAME>", "status").apply(status => status.loadBalancer.ingress[0].hostname);

    What's happening in this program:

    1. We create an Azure resource group that will contain our AKS cluster.
    2. We instantiate a managed Kubernetes cluster with the desired node size, count, and Kubernetes version (make sure to replace it with the version available and desired at the time you run the program).
    3. The kubeConfig output will provide us the necessary configuration to interact with our AKS cluster from tools such as kubectl.
    4. We define a Pulumi Kubernetes provider that is used to authenticate to the AKS cluster using the kubeConfig we exported earlier.
    5. The Helm chart for openunison-k8s-login-activedirectory is deployed using the Kubernetes provider. Adjust the repo, chart name, version, and the values to match the configuration according to your Helm Chart's documentation and your Active Directory setup.

    Next Steps:

    • You would typically put your Active Directory sensitive values into the Pulumi configuration or use Azure Key Vault for secrets management.
    • Note that you must input your Azure AD details in the placeholders specified.
    • Remember to update the version placeholder with the correct version of the Helm chart you wish to deploy.

    After defining this program in a .ts file, you'd run it using the Pulumi CLI, which will handle provisioning the resources as per the configuration specified. Use the output openunisonUrl to access the deployed application.

    Remember, this is a basic example and, in a real-world scenario, additional considerations such as role-based access control, network configuration, and monitoring should be taken into account.
