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


    To deploy the kube-janitor Helm chart on an Azure Managed OpenShift Service, you'll need to follow a series of steps to set up your OpenShift cluster, configure Kubeconfig, and then use the Helm chart to deploy kube-janitor. Below is a Pulumi program in TypeScript that will set up the cluster and deploy the Helm chart.

    First, you'll need to create an instance of the Azure Managed OpenShift service using Pulumi's azure-native.containerservice.OpenShiftManagedCluster resource. Then, you'll deploy the kube-janitor Helm chart to this cluster using the Pulumi Kubernetes provider.

    Here's an outline of what we'll do in the Pulumi program:

    1. Set up the required Azure Managed OpenShift Service using Pulumi's azure-native provider.
    2. Deploy the kube-janitor Helm chart to the OpenShift cluster using Pulumi's kubernetes provider.

    Detailed Explanation

    1. Azure Managed OpenShift Cluster: The azure-native.containerservice.OpenShiftManagedCluster resource sets up an Azure Managed OpenShift Service, which is a Kubernetes platform on Azure that provides a managed OpenShift cluster.

    2. Kube Configuration: Configure the Kubernetes provider with the generated Kubeconfig from the OpenShift cluster to interact with your Kubernetes resources.

    3. Helm Chart Deployment: With the kubernetes.helm.v3.Chart resource, Pulumi can deploy Helm charts to a Kubernetes cluster. You provide details like the chart name, version, and any custom values you want to apply to the Helm chart, which in this case will be for kube-janitor.

    Let's now start with the Pulumi program:

    import * as pulumi from "@pulumi/pulumi"; import * as azure_native from "@pulumi/azure-native"; import * as k8s from "@pulumi/kubernetes"; // Step 1: Provision an Azure Managed OpenShift Cluster const managedCluster = new azure_native.containerservice.OpenShiftManagedCluster("myOpenshiftCluster", { // Provide required properties here // Replace placeholders with actual values resourceGroupName: "myResourceGroup", location: "East US", // Specify the Azure region openShiftVersion: "4.3", // Specify the OpenShift version // Specify other necessary parameters according to your requirements }); // Step 2: Use the output of the OpenShiftManagedCluster to configure the Kubernetes provider. // The `kubeconfig` should be available as an output from the cluster resource. const k8sProvider = new k8s.Provider("myk8s", { kubeconfig: managedCluster.config.apply(c => c.kubeconfig), }); // Step 3: Deploy the kube-janitor Helm chart using the Kubernetes Helm Chart resource const janitorChart = new k8s.helm.v3.Chart("kube-janitor", { chart: "kube-janitor", // Replace with the repository that hosts your `kube-janitor` chart if it's different fetchOpts: { repo: "https://your-helm-chart-repository.com/", }, // Specify the namespace where the kube-janitor should be deployed namespace: "cleanup", // Configure any values for the kube-janitor chart (if required) values: { // ... insert custom values here }, }, { provider: k8sProvider }); // Export the cluster name and endpoint export const clusterName = managedCluster.name; export const clusterEndpoint = managedCluster.properties.apply(p => p.fqdn);

    Key Points

    • Ensure that you replace the placeholders with actual values regarding your OpenShift cluster setup (resourceGroupName, location, etc.).
    • If kube-janitor is hosted on a different Helm chart repository, update the repo field within fetchOpts.
    • Customize values for the Helm chart deployment as necessary for your environment.
    • The use of apply is a way to pull out the necessary details from the provisioned resources when they become available.

    This program creates an Azure Managed OpenShift cluster and then deploys the kube-janitor Helm chart to the cluster. You will need to have your Azure credentials configured for Pulumi, which typically involves logging in via the Azure CLI and then running pulumi up to deploy the stack.
