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

    TypeScript

    To deploy the Prometheus Exporter Helm chart on an Azure Managed OpenShift Service using Pulumi in TypeScript, we'll leverage the following Pulumi resources:

    • azure-native.containerservice.OpenShiftManagedCluster: This resource is used to create and manage an Azure OpenShift Managed Cluster. OpenShift is a Kubernetes distribution from Red Hat, optimized for enterprise application development and deployment.

    • kubernetes.helm.v3.Chart: This represents a Helm chart in Kubernetes which is essentially a package containing pre-configured Kubernetes resources. Helm charts make it easy to deploy and manage applications on Kubernetes clusters.

    Here is how you can perform the deployment:

    1. First, you will need to create an Azure OpenShift Managed Cluster using azure-native.containerservice.OpenShiftManagedCluster. You'll need to provide location, resource group name, and other necessary cluster configuration details.

    2. Once the cluster is provisioned, you will set up a Kubernetes provider pointing to your newly created OpenShift cluster. This is required so Pulumi knows where to deploy the Helm chart.

    3. With the Kubernetes provider set up, you can now use kubernetes.helm.v3.Chart to deploy the Prometheus Exporter Helm chart into your OpenShift cluster. You'll specify the chart name (which is assumed to be prometheus-exporter), and optionally, you can pass configuration values if needed.

    Now let's write the Pulumi program in TypeScript:

    import * as pulumi from "@pulumi/pulumi"; import * as azureNative from "@pulumi/azure-native"; import * as k8s from "@pulumi/kubernetes"; // Create an Azure OpenShift Managed Cluster const cluster = new azureNative.containerservice.OpenShiftManagedCluster("my-openshift-cluster", { // Required configuration: resourceGroupName: "myResourceGroup", location: "East US", // Choose the appropriate Azure location openShiftVersion: "4.3", // Specify the OpenShift version // You will need to specify additional required configuration such as agent pool profiles, network profile, etc. }); // Use the kubeconfig from the generated OpenShift cluster to interact with the Kubernetes API const provider = new k8s.Provider("openshift-k8s", { kubeconfig: cluster.kubeconfig.apply(kubeconfig => kubeconfig.rawData), }); // Deploy the Prometheus Exporter Helm chart const prometheusExporterChart = new k8s.helm.v3.Chart("prometheus-exporter-chart", { chart: "prometheus-exporter", version: "1.0.0", // Specify the version of the chart. // fetchOpts: { repo: "https://prometheus-community.github.io/helm-charts" }, // Uncomment and use the correct Helm repo URL. // values: { /* Specify any configuration values here. */ }, }, { provider }); // Export the OpenShift cluster's kubeconfig export const kubeconfig = cluster.kubeconfig;

    This program does the following:

    • It declares an Azure OpenShift Managed Cluster with the specified configuration parameters.
    • It creates a Kubernetes provider that uses the kubeconfig from the created OpenShift cluster.
    • It deploys the Prometheus Exporter Helm chart to the OpenShift cluster using k8s.helm.v3.Chart.

    Keep in mind that you need to fill in any placeholders (like the resource group name or the Helm chart configuration) with the actual values that match your requirements and environment.

    Once you run this Pulumi program, it would provision the resources on Azure and deploy the specified Helm chart on the created OpenShift cluster. If you need to apply any specific configurations to the Prometheus Exporter, you can pass those in the values field when declaring the prometheusExporterChart resource.

    Make sure you have Pulumi installed and configured with the appropriate Azure credentials before running this program. You can run this program by executing pulumi up in the terminal from the directory where the code is saved.
