1. Deploy the prometheus-container-resource-exporter helm chart on Opensshift


    To deploy the Prometheus Container Resource Exporter Helm chart on an OpenShift cluster using Pulumi, you will utilize the kubernetes.helm.v3.Chart resource from the Pulumi Kubernetes provider. This resource is a high-level Pulumi component that manages Helm chart deployments, abstracting away many of the details involved in setting up a Helm chart.

    The Prometheus Container Resource Exporter chart is a pre-packaged set of Kubernetes resources that collect container resource metrics and exports them to Prometheus, which is a widely-used monitoring and alerting tool.

    Here's how to deploy this Helm chart using Pulumi with TypeScript:

    1. Set up a new Pulumi project and stack if you haven't already.
    2. Install necessary packages by running npm install @pulumi/kubernetes.
    3. Use the Chart resource from the @pulumi/kubernetes/helm/v3 package.
    4. Point the chart to the OpenShift cluster by providing appropriate Kubeconfig credentials.

    Below is a TypeScript program that demonstrates how to accomplish this:

    import * as kubernetes from "@pulumi/kubernetes"; // Assuming your kubeconfig is set up, Pulumi will use that by default. // Otherwise, you'll need to configure the provider with the correct kubeconfig. // Create a Kubernetes provider instance for OpenShift. const openshiftProvider = new kubernetes.Provider("openshiftProvider", { // Specify the kubeconfig if not present in the default location // kubeconfig: "path-to-your-openshift-kubeconfig", }); // Deploy the prometheus-container-resource-exporter Helm chart. const prometheusExporterChart = new kubernetes.helm.v3.Chart("prometheus-exporter", { chart: "prometheus-container-resource-exporter", version: "chart-version", // Specify the chart version, if necessary fetchOpts:{ repo: "https://your-helm-chart-repository", // Replace with the Helm chart repository containing the chart }, // You can customize chart values here, if necessary. For example: // values: { // service: { // type: "ClusterIP", // }, // }, }, { provider: openshiftProvider }); // Export the service endpoint. export const serviceEndpoint = prometheusExporterChart.getResourceProperty("v1/Service", "prometheus-exporter", "status") .apply(status => status.loadBalancer.ingress[0].ip);

    In this program, you:

    • Import the @pulumi/kubernetes library, which contains helpers for deploying resources on Kubernetes clusters.
    • Create an instance of kubernetes.Provider specifically for OpenShift. You can configure the kubeconfig if it's not located in the default path.
    • Use the kubernetes.helm.v3.Chart resource to deploy the Prometheus Container Resource Exporter Helm chart from the specified chart repository. Note that you'll need to replace chart-version with the actual version of the Helm chart you want to deploy and https://your-helm-chart-repository with the URL of the repository containing the chart.
    • Optionally customize the Helm chart's values by providing them to the values field inside the chart specification.
    • Finally, export a service endpoint that you might consume from outside your cluster.

    The fetchOpts field is used to specify the repository from where the chart should be fetched. Please ensure you replace chart-version and https://your-helm-chart-repository with the correct values for your use case.

    Finally, a Stack export is defined that will output the IP address of the LoadBalancer created as part of the Helm chart's service. If your chart uses a different service type (like NodePort or ClusterIP), or if you have multiple services and want to export a different endpoint, you will need to adjust the service name and exported properties accordingly.
