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


    To deploy a Helm chart, such as the prometheus-container-resource-exporter, on a Rancher-managed Kubernetes cluster using Pulumi, you'll first need to have access to a Rancher Kubernetes cluster and have the rancher2 provider configured in your Pulumi program.

    You would typically use the rancher2 provider to manage resources within a Rancher instance, such as clusters, workloads, and apps, including Helm chart deployments. However, in the provided Pulumi Registry Results, there isn't a direct resource for deploying a Helm chart via the rancher2 provider. If this functionality is available in the rancher2 provider but not listed, you would follow the provider's documentation to deploy a Helm chart.

    Here I'll demonstrate how you can define a Pulumi program that assumes you already have a Rancher-managed Kubernetes cluster. The program will use Pulumi's Kubernetes provider to deploy a Helm chart into this cluster.

    Here's what you need to do:

    1. Set up Kubernetes Provider: Configure the Pulumi Kubernetes provider to connect to your Rancher Kubernetes cluster. This could involve setting the kubeconfig context to point to your Rancher cluster.

    2. Deploy Helm Chart: Use the helm.v3.Chart class from Pulumi's Kubernetes provider to deploy the prometheus-container-resource-exporter Helm chart into your cluster.

    Below is a TypeScript program that demonstrates the deployment steps:

    import * as pulumi from "@pulumi/pulumi"; import * as k8s from "@pulumi/kubernetes"; // Step 1: Configure the Kubernetes provider to connect to your Rancher Kubernetes cluster. const kubeconfig = "<YOUR_RANCHER_CLUSTER_KUBECONFIG>"; // Instantiate the Kubernetes provider with the kubeconfig. const k8sProvider = new k8s.Provider("k8s-provider", { kubeconfig: kubeconfig, }); // Step 2: Deploy the 'prometheus-container-resource-exporter' Helm chart. const prometheusChart = new k8s.helm.v3.Chart("prometheus-exporter", { chart: "prometheus-container-resource-exporter", // You'd replace 'CHART_REPO_URL' with the actual chart repository URL // and optionally specify the 'version', 'namespace', or 'values' properties. fetchOpts: { repo: "CHART_REPO_URL", }, }, { provider: k8sProvider }); // Export the name of the chart deployment export const chartName = prometheusChart.metadata.apply(meta => meta.name);

    In this program:

    • The kubeconfig needs to be replaced with the actual configuration content or path to your Rancher Kubernetes cluster's kubeconfig file.
    • The fetchOpts.repo should be replaced with the URL of the chart repository where prometheus-container-resource-exporter is hosted.

    You should ensure you have the correct chart name and other configurations required for the prometheus-container-resource-exporter chart, including setting the namespace if needed.

    This program assumes you have already set up Pulumi and logged into an account where you can run Pulumi programs. Run the program with the Pulumi CLI by executing pulumi up after saving the code in a file with a .ts extension. The program will prompt you for confirmation before proceeding to deploy the Helm chart to your Rancher Kubernetes cluster.

    Remember, managing Kubernetes resources with Pulumi requires a good understanding of Kubernetes concepts and the specifics of the resources you're deploying. Always refer to the official Helm chart documentation for any configuration and details needed to deploy the chart appropriately.
