1. Deploy the prometheus-process-exporter helm chart on Kubernetes


    To deploy the Prometheus Process Exporter using a Helm Chart on Kubernetes with Pulumi, we will use the kubernetes.helm.v3.Chart resource from Pulumi's Kubernetes provider. This resource allows you to deploy Helm charts from within your Pulumi program.

    The kubernetes.helm.v3.Chart resource takes several input properties that specify details about the Helm chart to be deployed. These include:

    • chart: The name of the Helm chart to deploy.
    • version: The version of the Helm chart to install.
    • fetchOpts: Optional settings related to fetching the Helm chart such as the Helm repository URL.
    • values: An object containing the values to override within the Helm chart.

    First, ensure you have set up your Pulumi environment and Kubernetes configuration. Install the Pulumi CLI and log in to your account. Ensure your kubeconfig file is correctly configured to connect to your Kubernetes cluster. Pulumi will use this kubeconfig file to communicate with your cluster.

    Now, let’s walk through the Pulumi code to deploy the Prometheus Process Exporter Helm chart.

    import * as kubernetes from "@pulumi/kubernetes"; // Define the Prometheus Process Exporter Helm chart details. const prometheusExporter = new kubernetes.helm.v3.Chart("prometheus-process-exporter", { chart: "prometheus-process-exporter", version: "X.Y.Z", // Replace X.Y.Z with the actual chart version you wish to deploy fetchOpts: { repo: "https://helm.example.com/", // Replace with the actual Helm repository URL }, values: { // Here, you can provide any values to customize your Prometheus Process Exporter deployment. // For example, you can configure the list of processes to monitor, set resource limits, or define service annotations. // Check the chart's `values.yaml` file for the full list of option. Below is just a placeholder for demonstration purposes. monitoredProcesses: [ "process1", "process2", // Add more processes as needed ], // ... Add more custom values if needed }, // You can also specify the namespace to deploy into, if omitted, it will use the default namespace. namespace: "monitoring", // Replace with your target namespace or omit for the default namespace }); // Optionally, export the name of the namespace Prometheus Process Exporter was deployed to export const namespace = prometheusExporter.namespace; // Export any other information that may be useful for your setup

    In this code:

    • We import the Pulumi Kubernetes package which allows us to interact with Kubernetes resources.
    • We create an instance of the Chart class which represents the Helm chart we want to deploy.
    • We specify the chart name (prometheus-process-exporter) and its version, which you need to replace with the correct chart version you wish to deploy.
    • We provide the Helm repository URL where the chart can be found.
    • We add a values property to customize the chart configuration, such as specifying the processes that the Prometheus Process Exporter should monitor.

    Replace X.Y.Z with the version of the Helm chart you want to deploy,
