1. Deploy the prometheus-jsonpath-exporter helm chart on Azure Managed Openshift Service


    To deploy the prometheus-jsonpath-exporter Helm chart on an Azure Managed OpenShift Service (ARO) using Pulumi, you first need an ARO cluster where the Helm chart will be installed. Our Pulumi program will include two main parts:

    1. Provisioning the ARO cluster using the azure-native.containerservice.OpenShiftManagedCluster resource.

    2. Deploying a Helm chart to the cluster with the kubernetes.helm.v3.Chart resource.

    The following steps are involved in this process:

    • Define a Pulumi project and import necessary packages.
    • Configure Azure credentials and location.
    • Provision an ARO cluster.
    • Configure Kubernetes provider to interact with the ARO cluster.
    • Deploy the prometheus-jsonpath-exporter Helm chart.

    Below is a detailed Pulumi TypeScript program to accomplish your goal:

    import * as pulumi from "@pulumi/pulumi"; import * as azure_native from "@pulumi/azure-native"; import * as k8s from "@pulumi/kubernetes"; // Step 1: Create an Azure Resource Group const resourceGroupName = "aroResourceGroup"; const resourceGroup = new azure_native.resources.ResourceGroup(resourceGroupName, { location: "EastUS", // Choose an Azure location }); // Step 2: Provision the Azure Red Hat OpenShift cluster const clusterName = "aroCluster"; const openShiftManagedCluster = new azure_native.containerservice.OpenShiftManagedCluster(clusterName, { resourceGroupName: resourceGroup.name, location: resourceGroup.location, openShiftVersion: "4.6", // Specify the OpenShift version // Define the network profile for the cluster (e.g., VNet settings) networkProfile: { vnetCidr: "", }, // Define node pools (compute nodes) agentPoolProfiles: [{ name: "primary", count: 3, vmSize: "Standard_DS3_v2", // Specify the virtual machine size }], // Red Hat pull secret to deploy OpenShift masterPoolProfile: { count: 3, vmSize: "Standard_D4s_v3", // Specify the master node virtual machine size }, // Red Hat pull secret to deploy OpenShift (You should replace <pull-secret> with your actual pull secret) authProfile: { identityProviders: [{ name: "OpenShift", provider: { clientId: "AzureAD", kind: "AADIdentityProvider", clientId: "<clientId>", clientSecret: "<clientSecret>", tenantId: "<tenantId>", }, }], }, }, { dependsOn: [resourceGroup] }); // Step 3: Using Kubernetes provider to interact with the ARO cluster const k8sProvider = new k8s.Provider("k8sProvider", { kubeconfig: openShiftManagedCluster.kubeconfig.apply(JSON.stringify), }); // Step 4: Deploy the prometheus-jsonpath-exporter Helm chart const chartName = "prometheus-jsonpath-exporter"; const prometheusChart = new k8s.helm.v3.Chart(chartName, { chart: "prometheus-jsonpath-exporter", version: "0.2.0", // Use the chart version compatible with your use case fetchOpts: { repo: "https://honestica.github.io/lifen-charts/", // The repository where the chart is hosted }, }, { provider: k8sProvider }); // Export the cluster's kubeconfig export const kubeconfig = openShiftManagedCluster.kubeconfig;

    Here's what each part of the code does:

    1. Import Pulumi packages: We are importing the necessary pulumi, azure-native, and kubernetes packages that allow us to interact with Pulumi, Azure, and Kubernetes constructs respectively.

    2. Create Resource Group: We define the ResourceGroup where all our Azure resources will live. This is a logical grouping required by Azure to manage resources.

    3. Provision ARO Cluster: Using the OpenShiftManagedCluster resource, we provision an ARO cluster, specifying properties like the version of OpenShift, the network profile, and node sizes. You'll need to replace the placeholders with actual values, particularly the Red Hat pull-secret which can be obtained from Red Hat.

    4. Kubernetes Provider: We define a Kubernetes provider that uses the kubeconfig generated by the ARO cluster. This allows Pulumi to communicate with the Kubernetes cluster to deploy applications.

    5. Deploy the Helm Chart: We use the Chart resource from the @pulumi/kubernetes package to define the deployment of the prometheus-jsonpath-exporter Helm chart. The chart option specifies the name of the chart, and fetchOpts specifies the chart's repository.

    6. Export kubeconfig: Finally, we export the kubeconfig of the ARO cluster to allow access using kubectl or other Kubernetes tooling.

    Make sure to install the required Pulumi plugins for Azure and Kubernetes by running the following command:

    pulumi plugin install resource azure-native <version> pulumi plugin install resource kubernetes <version>

    Replace <version> with the specific version number of the package you wish to install.

    To run this program, you will need to install the Pulumi CLI, set up your Azure credentials, and create a new Pulumi TypeScript project. Then, you can copy and paste the above code into your index.ts file. You may use pulumi up to create and apply your deployment.

    Lastly, remember to replace placeholder values like <pull-secret>, <clientId>, <clientSecret>, and <tenantId> with real values from your Azure and Red Hat OpenShift service accounts.
