1. Deploy the prometheus-haproxy-exporter helm chart on Rancher


    To deploy the prometheus-haproxy-exporter Helm chart to a Rancher-managed Kubernetes cluster using Pulumi, we will follow these steps:

    1. Import the necessary Pulumi packages to manage Rancher resources.
    2. Create a new Pulumi stack, which represents an isolated deployment target managed by Pulumi.
    3. Use the rancher2 provider to interact with your Rancher instance.
    4. Deploy the prometheus-haproxy-exporter Helm chart using the Pulumi Kubernetes provider.

    Below is a detailed Pulumi program written in TypeScript that demonstrates how to accomplish these steps:

    import * as pulumi from "@pulumi/pulumi"; import * as k8s from "@pulumi/kubernetes"; import * as rancher2 from "@pulumi/rancher2"; // Step 1: Configure Rancher provider // Replace the following variables with your Rancher access credentials and Rancher API URL. const rancherApiUrl = "https://<rancher-server-url>/v3"; const rancherAccessKey = "<rancher-access-key>"; const rancherSecretKey = "<rancher-secret-key>"; const rancherClusterId = "<rancher-cluster-id>"; // ID of the cluster where you want to deploy the chart // Create a new rancher2 provider instance to interact with Rancher const rancherProvider = new rancher2.Provider("rancher", { apiUrl: rancherApiUrl, accessKey: rancherAccessKey, secretKey: rancherSecretKey, }); // Use the produced kubeconfig to configure the Kubernetes provider. const config = new pulumi.Config(); const kubeConfig = config.requireSecret("kubeconfig"); // Ensure the kubeconfig is set in the Pulumi config // Step 2: Configure Kubernetes provider const k8sProvider = new k8s.Provider("k8sProvider", { kubeconfig: kubeConfig.get(), }); // Step 3: Install the prometheus-haproxy-exporter Helm chart // Replace 'namespace' with the name of the pre-existing namespace where you want to deploy // or remove the 'namespace' property to install it in the default namespace. const chart = new k8s.helm.v3.Chart("prometheus-haproxy-exporter", { chart: "prometheus-haproxy-exporter", version: "1.4.0", // Specify the chart version you want to deploy fetchOpts: { repo: "https://prometheus-community.github.io/helm-charts", // The Helm repo URL where the chart is located }, namespace: "monitoring", }, { provider: k8sProvider }); // Export the Helm chart status export const helmChartStatus = chart.status;

    In this program, replace all placeholders like <rancher-server-url>, <rancher-access-key>, <rancher-secret-key>, and <rancher-cluster-id> with your actual Rancher server URL, access key, secret key, and the ID of the cluster you want to manage with Pulumi. You'd also need to ensure you have a kubeconfig file for your Kubernetes cluster, which should be securely stored in the Pulumi config as kubeconfig.

    The rancher2.Provider is used to configure the Rancher provider with necessary credentials, and then we instantiate a k8s.Provider, which will interface with Kubernetes. The kubernetes.helm.v3.Chart resource represents a Helm chart, which is used to deploy the prometheus-haproxy-exporter chart from the Prometheus community Helm repository.

    After running pulumi up, Pulumi will interact with Rancher to create the needed Kubernetes and Helm resources. The status of the Helm chart deployment is exported, so you can observe the outcome of your deployment once Pulumi has executed.

    Remember to run pulumi up to preview and then perform the deployment of the Helm chart in your cluster. If you are new to Pulumi, you would first need to install Pulumi and set up the Pulumi CLI accordingly. Visit the Pulumi Installation Guide for detailed setup instructions.
